Check the connectors, for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are the connectors and terminals in good condition?
YES: An open or short circuit may be present in the power supply line to
the TCL/ASC-ECU. Repair the wiring harness between TCL/ASC-ECU
connector A-32 terminal 32 and ignition switch connector C-308 terminal
4. Go to Ste
p 8.

NO: Repair or replace the damaged component(s). Then go to Step 8.
STEP 3. Measure the resistance at TCL/ASC-ECU connector A-32.
1. Disconnect the connector A-32, and connect special tool ABS Check
Harness (MB991952) to the wiring harness-side connector.
2. Measure the resistance between terminal 12, 34 and ground. It should be 2
ohms or less. NOTE: Do not connect special tool ABS Check Harness
(MB991952) to the TCL/ASC-ECU.

Q: Are the connectors and terminals in good condition?
YES: An open circuit may be present in the ground circuit. Repair the
wiring harness between TCL/ASC-ECU connector A-32 terminals 12, 34
and the body ground. Then go to Step 8.
NO: Repair or replace the damaged component(s). Then go to Step 8.
STEP 5. Check the battery.
Check the battery (Refer to BATTERY TEST
).
Q: Is the battery in good condition?
YES: Go to Step 6.
NO: Charge or replace the battery. Then go to Step 8.
STEP 6. Check the charging system.
Check the charging system (Refer to GENERATORS & REGULATORS
).
Q: Is the charging system in good condition?
YES: Go to Step 7.
NO: Repair or replace the charging system component(s). Then go to Step
8.
STEP 7. Retest the system.
Q: Can the TCL/ASC-ECU communicate with the scan tool (MUT-III Sub
Assembly)?
YES: It can be assumed that this malfunction is intermittent. Refer to
HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
NO: Replace the TCL/ASC-ECU. Then go to Step 8.
STEP 8. Retest the system.
Q: Can the TCL/ASC-ECU communicate with the scan tool (MUT-III Sub
Assembly)?

CIRCUIT OPERATION
The G and yaw rate sensor is energized by the ignition switch (IG2) through
multi-purpose fuse 13 and the G and yaw rate sensor terminal 1. If the power supply to the G and yaw rate sensor has failed, TCL/ASC-ECU
related DTC U1105 is set.
