In case of lower resistance or higher voltage difference, repair wiring harness.If result is ok reconnect everything delete error code, check if error code appears again (activat PCV via diagnosis) . If error is not detected again. The error is intermittent try to reproduce the error by moving cables and connectors. If error can not be reproduced no further action is possible.

With engine running turn the steering wheel to its end positions, read the steering angle values via diagnosis and check if the read values are within the allowed range defined in the dataset. If fault is still active, replace the steering angle sensor.

Difference between measured full pressure and supply pressure > 2.2 bar

Signal invalid

EBS System in pneumatic backup.

– Driver informed by RED warning sign and brake malfunction indication.

– Changed Pedal feeling (need to brake harder).

– System pressure limited to 10 bar.

– Damaged or plugged piping from pressure supply to EPM

– Damaged or open piping from EPM to PCV

– Received supply pressure values from APM incorrect

– EPM damage

Diagnostic Service 14. No additional action is needed

Check pneumatic piping between EPM and supply pressure, and between EPM and brake chamber. Check silencer. Check piping and components for possible leakages.

If not problem was seen: Ensure that reservoirs are fully charged (until cut-off pressure). Control maximum pressure at the corresponding EPM via diagnostics. Read pressure value via diagnostics. Measure pressure in brake chamber externally with 2% precision. Compare the two pressure values with each other and  with the defined nominal maximal braking pressure.

If measured pressures are smaller than (nominal maximal braking pressure – 1bar), then EPM should be replaced.

If difference between read and externally measured pressure is greater than 0.5 bar + 5%, then EPM should also be replaced.

EBS System in pneumatic backup.

– Driver informed by RED warning sign and brake malfunction indication.

– Changed Pedal feeling (need to brake harder).

– System pressure limited to 10 bar.

– Damaged piping or part between EPM and wheel brake

– Damaged piping or part between EPM and supply pressure

– Received supply pressure values from APM incorrect

– EPM damaged

Diagnostic Service 14. No additional action is needed

Check pneumatic piping between EPM and supply pressure, between EPM and brake chamber. Check piping and components for possible leakages.

If not problem was seen: Ensure that reservoirs are fully charged (until cut-off pressure).

Measure pressure in supply reservoir and compare with read out pressure from APM via diagsnotics.

Switch to Aftermarket mode with diagnostics. Control pressure at EPM via diagnostics increased from 0 to 8 bar with 1 bar steps. Read pressure values via diagnostics. Measure pressure in brake chamber externally with 2% precision.

If difference between read and externally measured pressure is greater than 0.5 bar + 5%, then EPM should be replaced.

If difference between pressure demanded by diagnostics and value read by diagnostics is greater than 0.5 bar + 5%, then EPM should be replaced.

Check pneumatic piping to the trailer including coupling head (high leakage); Check pneumatic piping to the APM (if piping is not according to the specification /i.e. wrong dimention, bend on the piping/, supply pressure information can be wrong);

Compare supply pressure of the TCM measured by external pressure gauge (with a maximum tolerance of 2

%) with the supply pressure information transmitted by the APM; If the pressure difference is higher than 1 [bar] + 5 %, then check the APM;

Check the wiring (pressure sensor ground and signal) between the TCM and the central ECU; Repair if faulty;

Set ECU into Aftermarket Diagnostic Mode; Press the brake pedal fully; Check pressure of the TCM (yellow coupling) with an external pressure gauge with a maximum tolerance of 2 %; Compare the pressure with the pressure of the TCM read via diagnosis; If difference is higher than 0,5 [bar] + 5 % then replace the TCM;

Otherwise delete fault codes and check for the fault code

Circuit / Component Protection Time-Out

– ABS function not fully operational, possibility for wheel locking when braking. Driver informed by YELLOW warning and ABS malfunction indication.

– ESP switched off. Driver informed by YELLOW warning and ESP malfunction indication

– Fault of at least one wheel speed sensor or its mounting

– Damages of at least one tone wheel,

– Noisy wheel speed signal,

– Differences in tyre sizes,

– Puncture of a tyre,

– Continuous brake force on a wheel (without brake pressure).

Diagnostic Service 14. No additional action is needed

Check wheel speeds in snapshot to see,  which wheel can cause the fault.

Check tyre for size and correct air pressure, check pneumatic and mechanical parts of wheel brakes. Check wheel speed signal components: check cable, sensor and tone wheel. Check if pneumatic and electronic installation to wheels correspond to each other (if pneumatic pipes are mixed up). Check if  configuration stored in the ECU corresponds to vehicle brake system layout: number and location of sensed wheels, axle type such as driven, liftable. Check if configuration stored in the central ECU corresponds to wheel rolling circumference and tone-wheel teeth number. If those do not conform, then correct the configuration values or change the part of the vehicle.

Ensure that reservoirs are fully charged (until cut-off pressure). Switch to Aftermarket mode with diagnostics. Control pressure at EPM via diagnostics increased from 0 to 8 bar with 1 bar steps. Read pressure values via diagnostics. Measure pressure in brake chamber externally with 2% precision.

If difference between read and externally measured pressure is greater than 0.5 bar + 5%, then EPM should be replaced.

C100B15

Feedback does not correspond to the actual valve low state.

Circuit Short To Battery or Open

Rear axle steering will be in passive failuremode i.e. the axle will be self steered and hydraulically damped

– Damaged wire(s) or connector(s)

– Valve damaged

– ECU damaged

Diagnostic Service 14. No additional action is needed

– Check the wires and connectors between central ECU and cutoff valve for short-circuits and for open circuit. The insulation resistance must be higher than 200 kOhm and the wire resistance should be less than 3 Ohm.

– If the resistance of the cutoff valve is higher than 28 O replace the cutoff valve.

– If error is still active replace the central ECU.

Rear Active Steering Cutoff Valve

C100B71

Axle moves > 2 degrees when cutoff valve is opened and a target value is requested.

Actuator Stuck

Rear axle steering will be in passive failuremode i.e. the axle will be self steered and hydraulically damped

Valve damaged (Valve is stuck in closed position)

Diagnostic Service 14. No additional action is needed

Replace hydraulic valve

Rear Active Steering Cutoff Valve

C109B68

External CAN signals not available

Event Information

Rear axle steering will be in active failuremode i.e. the axle will be actively steered towards target angle zero ( straight ahead )

– Damaged wire(s) or connector(s)

– Sending ECU or component

Diagnostic Service 14. No additional action is needed

Check other ECUs for related fault codes
