ContiPressureCheck™

FAQ

General

Automatic wheel exchange detection (SWE – SingleWheelExchange): Why doesn’t the ContiPressureCheck automatically detect that a wheel with a new tyre sensor has been exchanged?

The ContiPressureCheck normally detects the replacement of a single wheel with a new tyre sensor automatically after driving for 5–10 minutes.

If this does not work, it may be for one of the following reasons:

  • More than one tyre with a new sensor has been replaced.
  • ATL (automatic trailer learning) has been activated.
  • A lift axle is raised. The new tyre sensor will only be detected when driving with lowered lift axles. This is independent of the position of the wheel that was replaced.
What pressure range is shown on the display?

The display range is between 0 and 11.9 bar (173 psi).
Note: Pressures above 11.9 bar (173 psi) are displayed as 11.9 bar (173 psi).

Tyre Sensor and Fixation

Can other cleaners be used to clean the tyre and rubber container?
  • As a result of internal tests performed by Continental Reifen Deutschland GmbH, the use of Liquidbuffer from Tiptop is recommended (see Installation instructions) for cleaning the adhesive surfaces.

  • If any other products are used for cleaning, Continental Reifen Deutschland GmbH cannot guarantee that adhesion is sufficient for the application.

  • Brake cleaner or similar substances may never be used for cleaning the adhesive surfaces since this will impair the adhesive process. Possible consequences: The tyre sensor and the rubber container can become unstuck and damage the tyre  in the long term.

  • Furthermore, the use of brake cleaner can damage the tyre.

Can adhesives other than CB2250 be used to fix the rubber container?
  • Continental Reifen Deutschland GmbH recommends using Cyberbond's CB2250 to affix the rubber container on the basis of tests that they carried out specifically for this purpose.

  • If other products are used to fix the container, Continental Reifen Deutschland GmbH cannot guarantee sufficient adhesion for this purpose.

My tyre size is not listed as an authorized tyre size in the User Manual. Can the ContiPressureCheck system be used for this size?

An up-to-date list can be found here (Permissible Tyre Sizes). Alternatively, please contact your ContiPressureCheck vendor.

If using industrial tyres, please contact your ContiPressureCheck vendor.

Can the ContiPressureCheck be used for industrial tyres as well?

If using industrial tyres, please contact your ContiPressureCheck vendor.

Can the tyre sensors be used with solid rubber tyres?

No.

Can the tyre sensors be used with tube-type tyres?

No.

What brands of tyre can the tyre sensors be fitted to?

The tyre sensors can be installed in all branded tyres with a rubber inner liner.

Will the attached tyre sensors result in an imbalance in the tyre?

No. A tyre sensor with its rubber container weighs approx. 38 g.

What causes the "Sensor is LOOSE" error message?
  • The tyre sensor has popped out of the rubber container.

  • The rubber container and tyre sensor have come loose from the tyre.

  • The tyre sensor has been inserted into the rubber container incorrectly (top-first).

Why can’t I reuse a tyre sensor that displays the warning "Sensor is LOOSE"?

The tyre sensor is not designed for uncontrolled free movement within the tyre, or for installation in the wrong position. In either case, initial damage to the tyre sensor could occur during operation, which could lead to the premature failure of the tyre sensor if it continues to be used.

Warnings

The warning message LOW PRESSURE appears when starting to drive, but after a while it disappears. Is the ContiPressureCheck not working correctly?

The ContiPressureCheck is working correctly. The pressure is low, which is the reason for the warning message. While driving, the tyre warms up and the tyre pressure increases. The increase may be enough to reset the warning automatically.

Corrective action: Set the tyre to the recommended pressure when the tyre is “cold”, i.e. the state in which the tyre is in after having stood outdoors for several hours, not exposed to intense sunlight.

Why are several tyre sensors suddenly not being received for an extended period (warning message: NO SIGNAL)?

Reception from the relevant tyre sensors is in the borderline range. Temporary interference could block reception from the relevant tyre sensors. Interference could be caused by:

  • A layer of mud, snow, or ice on the central control unit (CCU) or additional receiver,
  • Inverters for operating coffee machines, kettles, etc.,

  • Other electromagnetic interference.

Possible corrective action: The position/orientation of the central control unit (CCU) or additional receiver should be adjusted to bring the RSSI values for the relevant tyre sensors above the recommended thresholds (see chapter 6.7 in the User Manual for the handheld tool).

Is there a warning message if the pressure is too high?

No.

Installation and Modification

How to speed up the tyre sensor fetching process?
  • The tyre sensor's position must be aligned with the DOT.
  • When fitting the tyre, ensure that the DOT and the valve are in line with each other.
  • For dual tyres, the wheels should be fitted such that the valves on the inner and outer sections are offset by 180°.

This will make the tyre sensors very easy to locate using the valves on the vehicle.

The tyre sensor on the inner dual tyre section is not found during the fetching process. What can I do?
  • In rare cases, the tyre sensor may not be detected if it is simultaneously in the inner dual tyre section and in the tyre ground contact area. Please move the vehicle forward or backward by half of one tyre circumference, then repeat the fetching process.
  • If this inner section can be accessed directly, continue the fetching process by guiding the handheld tool directly along this dual tyre. 

The configuration process was interrupted after fetching some or all tyre sensors. When the configuration process is resumed with "Resume installation," it has to start from the first tyre; why?

Resuming the installation after an interruption is no longer necessary with the latest hand-held tool software. Please update the software on your hand-held tool. The software and the relevant instructions for updating can be found under: www.contipressurecheck.com/hht.

A warning appears on the trailer while driving. After the vehicle has been switched off, the warning lamp (Pressure Check Indicator) continues to flash. Is there a malfunction in the ContiPressureCheck?

The ContiPressureCheck is supplied through KL30/KL31 (continuous supply) for this trailer. Once the vehicle has been turned off, the flashing will stop after approx. 30 minutes.

Please note: During normal operation, the ContiPressureCheck on the trailer requires approximately 60 mA (24 V) or 55 mA (12 V) of current.

Can the ContiPressureCheck on the trailer be connected to the continuous supply (KL30/KL31) as well?

Yes.
Please note: During normal operation, the ContiPressureCheck on the trailer requires approximately 60 mA (24 V) or 55 mA (12 V) of current.

After the installation or after modification of the parameters, the configuration/modification has not been applied. Why is that?

For the ContiPressureCheck to use the new parameters, it must be restarted.

  • To do this, turn off the ignition for at least 30 seconds.
  • For trailers with a ContiPressureCheck supplied through a KL30/KL31, the ContiPressureCheck must be switched off using the main switch for at least 30 seconds.
Why is the orientation in which the CCU or additional receiver is installed important?

The recommended direction of installation ensures that the components, and in particular their cables, are better protected from road chip damage.

  • Optimum orientation of the central control unit (CCU): cable outlet facing “backward” (in the opposite direction to the direction of travel).
  • Optimum orientation of the additional receiver: impact protection pointing “backward” (in the opposite direction to the direction of travel), cable outlet upward.

Positioning and orienting the CCU or additional receiver as recommended also ensures optimum reception from the tyre sensors.

How do I find out the recommended cold pressure (RCP) for the tyres?

See the technical tyre data book from the corresponding tyre manufacturer.

Here you will find the Continental technical data book.

Why must impact protection be used for the additional receiver?

If impact protection is not used:

  • The ContiPressureCheck system may not be used for transporting hazardous materials (ADR),
  • The additional receiver could become damaged,
  • The reception range of the additional receiver is reduced.

During a CCU software update, the display is repeatedly restarted. Is this normal?

Yes, it may restart up to twice.

During a CCU software update, SYSTEM ERROR appears on the display. Is this normal?

Yes. Once the update process has been completed successfully, the SYSTEM ERROR message will disappear automatically.

Vehicle Types and Vehicle Combinations

What vehicle types and vehicle combinations can the ContiPressureCheck be installed in?

A ContiPressureCheck system can monitor a maximum of 8 axles and 32 tyres.

Your ContiPressureCheck vendor can specify types and combinations suitable for the ContiPressureCheck.

How do I check whether a trailer is suitable for monitoring through the towing vehicle (ATL or MARRIED)?

Your ContiPressureCheck vendor can provide you with information on suitability.

Alternatively: Configure the towing vehicle and trailer as MARRIED and then carry out a test drive.

How many trailer tyres can be monitored by ATL?
  • The ContiPressureCheck can monitor a maximum of 32 tyres (including towing vehicle and trailer).

  • Example 1: If the towing vehicle has 6 tyres, ATL can be used to monitor a maximum of 26 additional tyres.

  • Example 2: The towing vehicle has 10 tyres and the trailer has 24 tyres. In this case, only the first 22 acquired tyres will be monitored; the remaining two tyres will not be taken into account by the ContiPressureCheck.

Which trailer types are suitable for monitoring by Automatic Trailer Learning (ATL) with Position Recognition?

Trailers with up to three axles, which either have single tyres or dual tyres on all axles. Additionally, a three-axle trailer with single tyres at the first axle and dual tyres at the second and third axle are suitable. 

Approval

Does the ContiPressureCheck system on the vehicle need to be approved in Germany?

No. The ContiPressureCheck system has an ABE (General Operating Permit) (KBA 91387). After installation, acceptance by TÜV is no longer necessary.

What is the ContiPressureCheck system's safety rating?

The ContiPressureCheck system is not a safety-related system. It is classified and designated as a comfort system. 

Is the ContiPressureCheck system suitable for ADR vehicles (hazardous goods)?

When used for its intended purpose and when the instructions provided by the manufacturer, Continental, are followed, the ContiPressureCheck fulfills the ADR's requirements for vehicle types AT, FL, OX, EX/II, and EX/III.

For the usage of the hand-held tool at ADR vehicles, please refer to the  User Manual for the handheld tool.

Handheld Tool

Why do the date and time need to be set every time the handheld tool is switched on?

The extra battery for the handheld tool's internal clock is completely drained. Possible causes:

  • The handheld tool has been charged incorrectly. To charge the handheld tool correctly, connect the charger and then switch on the tool. After a few seconds, the screen dims and the charging symbol is displayed.
  • The additional battery will be fully charged after 48 h. This can be done at a convenient time (e.g. during the weekend).

Note: The date and time is only needed for the log files. Use of date and time can be switched off using the menu item "Setup/Tool Properties/Use date". The date and time must then be entered manually in the log file printouts.

Why can't the handheld tool be used while it is charging?

For transmission licensing reasons (homologation).

Why can't the handheld tool be switched on even when it has been connected to the charger?

The handheld tool's battery is completely drained. Switch the handheld tool on again after charging for five minutes so that the additional battery for the internal clock can also charge correctly.
