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 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:)
Damaged wiring harness or connector Defective battery Charging system failed Malfunction of the steering wheel sensor
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

1. Disconnect the connector C-312.
2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between terminal 2 and ground. It should measure
approximately 12 volts (battery positive voltage).
