Sensor data error - no pulses
â–¶ How to fix
1) Check cable harness. 2) Check for evidence of tampering. 3) Pair another motion sensor with the tachograph and check if it is working. 4) If the other motion sensor is working, replace the faulty motion sensor and perform a calibration of the tachograph system.
What you'll see
tbd
System reaction
* Event/Fault data 0x09 is stored in the tachograph. * Warning displayed in the tachograph display. * System event in TCO1 CAN message is set to active. * Tachograph warning displayed in the instrument cluster.
Diagnostic depth
Detection
Motion sensor data incorrect. Tachograph receives speed data value from motion sensor without receiving any real time pulses.
Possible cause
* Fault in cable harness. * Sensor fault.
