YES: An open circuit may be present in the ground circuit. Repair the
wiring harness between steering wheel sensor connector C-312 terminals 5
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 steering wheel sensor 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 steering wheel sensor. Then go to Step 8.
STEP 8. Retest the system.
Q: Can the steering wheel sensor communicate with the scan tool (MUT-
III Sub Assembly)?
YES: The
procedure is com
plete.

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.

Malfunction of the G and yaw rate 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

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
).
