The G and yaw rate sensor outputs the signal to ASC-ECU via the special CAN bus lines.
|
|
This DTC is set when the ASC-ECU cannot receive the signal from the G and yaw rate sensor
although there is no abnormality in ASC-ECU supply voltage.
|
|
- Wiring harness or connector failure for the special CAN bus lines between
ASC-ECU and the G and yaw rate sensor
- G and yaw rate sensor malfunction
- ASC-ECU malfunction
- External noise interference
- Connector disconnected or improperly connected
- Stretched or broken wires
|

Required Special Tools:
- MB991958: Scan Tool (M.U.T.-III Sub Assembly)
- MB991824: Vehicle Communication Interface (V.C.I.)
- MB991827: M.U.T.-III USB Cable
- MB991910: M.U.T.-III Main Harness A
|
|
Use M.U.T.-III to diagnose the CAN bus lines.
|
|

Replace the G and yaw rate sensor.(Refer to .)
Then go to Step 6.
|
|
|
|
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent
Malfunction .)
|
|
|
|
