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).

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 steering wheel sensor. Repair the wiring harness between steering
wheel sensor connector C-312 terminal 2 and ignition switch connector C-
308 terminal 4. Go to Step 8.
NO: Repair or replace the damaged component(s). Then go to Step 8.
STEP 3. Measure the resistance at steering wheel sensor connector C-312.
1. Disconnect the steering sensor connector C-312, and measure at the
harness side connector.
