Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-P165314

Condition
Central electronic module (CEM) sends a frequency-modulated signal to speed-dependent power steering module (HPAS) which is in proportion to the speed signal that the Central electronic module (CEM) receives from the Brake control module (BCM) via the CAN-net. Central electronic module (CEM) also monitors the signal cable to the control module for speed-dependent power steering (HPAS).

Note! The diagnostic trouble code may also be generated if the fuse for the control module for speed-dependent power steering is defective.

The diagnostic trouble code (DTC) is stored if the control module detects that:
- The signal cable has an open circuit or if the voltage on the signal cable is constantly low.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- None.

Possible source
- The signal cable is short-circuited to ground.
- Open circuit on signal cable.
- Fuse in the circuit is not working.

Fault symptom[s]
- Power steering control does not function
