P1606

CAN Timeout, ASR/MSR

Diagnosis conditions
- Battery positive voltage between 10 V and 16 V
- Switch on the ignition
- Internal function test for DME control module

Possible fault cause
- No signals in PSM control module

Affected pin
DME control module connector A, pin 60, 'CAN - HIGH'
DME control module connector A, pin 58, 'CAN - LOW'

Diagnosis/troubleshooting

NOTE: If the received signal does not appear via the CAN data bus for multiple control modules, the CAN data bus must be checked for an open circuit and/or a short circuit. In this regard, see 'Checking instructions/CAN data bus'.

NOTE: The CAN message, 'CAN Timeout, ASR/MSR', is sent by the PSM control module when important 'ASR/MSR system' signals are missing.

NOTE: If connector A is disconnected from the DME control module and the ignition is or was switched on, the 'DME Control Module Timeout' fault is recorded in many control modules.

NOTE: If control module connector A was disconnected from the DME in the course of troubleshooting or if the voltage supply was interrupted elsewhere (battery, fuse), the throttle adjusting unit must be adapted.
