Q: Are TCL/ASC-ECU connector A-32 and ABS sensor < front: LH >
connector A-14 damaged?
YES: Repair or replace the damaged component(s). Then go to Step 16.
NO: Open or short circuit may be present in the front right ABS sensor
circuit. Repair the wiring harness between TCL/ASC-ECU connector A-
32 (terminals 22 and 31) and front left ABS sensor A-14 (terminals 2 and
1). Then go to Step 16.
STEP 13. Check TCL/ASC-ECU connector A-32, intermediate connector
C-32 and ABS sensor < rear: RH > connector D-10 for loose, corroded or
damaged terminals, or terminals pushed back in the connector.

Q: Are TCL/ASC-ECU connector A-32, intermediate connector C-32 and
ABS sensor < rear: LH > connector D-15 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 left ABS sensor
circuit. Repair the wiring harness between TCL/ASC-ECU connector A-
32 (terminals 6 and 7) and rear left ABS sensor D-10 (terminals 1 and 2).
Then go to Step 16
.
STEP 15. Recheck for diagnostic trouble code.
Check again if the DTC is set.
1. Turn the ignition switch to the "ON" position.

2. Turn the ignition switch to "ON" position.
3. Diagnose the CAN bus line.
Q: Is the check result satisfactory?
YES: Go to Step 2
NO: Repair the CAN bus lines (Refer to DIAGNOSTIC TROUBLE
CODE DIAGNOSIS
or DIAGNOSIS < VEHICLES WITHOUT
ADVANCED AIR BAG
). On completion, go to Step 6.
STEP 2. Using scan tool MB991958, read the steering wheel sensor
diagnostic trouble code.
Check if a steering wheel sensor DTC is set.
Q: Is the DTC set?
YES: Diagnose the steering wheel sensor by referring to DIAGNOSTIC
TROUBLE CODE CHART
.
NO: Go to Step 3.
STEP 3. Using scan tool MB991958 read any of the diagnostic trouble
code.
Check if a DTC, which relates to CAN communication-linked systems below,
is set.
Power train control module
DTC U1100: ABS-ECU time-out
Combination meter DTC 011: ABS-ECU time-out
Q: Is the DTC set?
YES: Go to Step 4. NO:
Go to Step
5.

STEP 2. Using scan tool MB991958 read the diagnostic trouble code.
Check if a DTC, which relates to CAN communication-linked systems below,
is set.
Power train control module
DTC U1102: ABS-ECU time-out
Combination meter DTC 018: ABS-ECU time-out
Q: Is the DTC set?
YES: Go to Step 3.
NO: Go to Step 4.
STEP 3. Recheck for diagnostic trouble code.
Recheck if the DTC is set.
1. Erase the DTC.
2. Turn the ignition switch to "ON" position.
3. Check if the DTC is set.
Q: Is the check result satisfactory?
YES: A poor connection, open circuit or other intermittent malfunction is
present in the CAN bus lines between the G and yaw rate sensor and the
TCL/ASC-ECU (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
).
NO: Replace hydraulic unit (integrated with TCL/ASC-ECU) and then go
to Step 4.
STEP 4. Recheck for diagnostic trouble code.

CIRCUIT OPERATION
The steering wheel sensor is energized by the ignition switch (IG2) through
multi-purpose fuse 13 and the steering wheel sensor terminal 2. If the power supply to the steering wheel sensor has failed, scan tool (MUT-III
Sub Assembly) will not be able to communicate with it.
TROUBLESHOOTING HINTS (The most likely causes for this case:)

STEP 1. Measure the voltage at G and yaw rate sensor connector C-36.
1. Disconnect the G and yaw rate sensor connector C-36, and measure at the
harness side connector.
2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between terminal 1 and body ground.
Voltage should measure battery positive voltage (approximately 12
volts
).
