Q: Are TCL/ASC-ECU connector A-32, intermediate connector C-32 and
ABS sensor < rear: RH > connector D-10 damaged?
YES: Repair or replace the damaged component(s). Then go to Step 16.
NO: Open or short circuit may be present in the rear right ABS sensor
circuit. Repair the wiring harness between TCL/ASC-ECU connector A-
32 (terminals 8 and 9) and rear right ABS sensor D-10 (terminals 1 and 2).
Then go to Step 16
.
STEP 14. Check TCL/ASC-ECU connector A-32, intermediate connector
C-32 and ABS sensor < rear: LH > connector D-15 for loose, corroded or
damaged terminals, or terminals pushed back in the connector.

The TCL/ASC-ECU gathers information regarding lateral and longitudinal
accelerations and yaw rate, through the CAN bus line from the G and yaw rate
sensor. TCL/ASC DTC SET CONDITIONS The TCL/ASC-ECU activates the G and yaw rate sensor via a CAN bus line in
order to diagnose the sensor whenever the ignition switch is turned on. If the G and
yaw rate sensor does not respond to this request, this DTC will be set. TROUBLESHOOTING HINTS (The most likely causes for these DTC are to set are:)
Current trouble
The CAN bus line is defective. Damaged connector(s) The G and yaw rate sensor is defective. The TCL/ASC-ECU is defective.
Past trouble Carry out diagnosis with particular emphasis on connector(s) or wiring harness
between the TCL/ASC-ECU and the G and yaw rate sensor. For diagnosis
procedures, refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.
CAUTION: To prevent damage to scan tool MB991958,
