2. Turn the ignition switch to the "ON" position.
3. Diagnose the CAN bus line.
Q: Is the check result satisfactory?
YES: Check and repair the power supply circuit system (Refer to DTC
C1860: POWER SUPPLY HIGH VOLTAGE, DTC C1861: POWER SUPPLY LOW VOLTAGE
).
NO: Repair the CAN bus lines (Refer to DIAGNOSTIC TROUBLE
CODE DIAGNOSIS
or DIAGNOSIS < VEHICLES WITHOUT
ADVANCED AIR BAG
).
INSPECTION PROCEDURE 2: Communication between Scan Tool and the steering wheel sensor is not possible.

TECHNICAL DESCRIPTION (COMMENT) If the scan tool (MUT-III Sub Assembly) can not communicate with the steering
wheel sensor, the CAN bus lines may be defective. If the ASC system does not
work, the steering wheel sensor or its power supply circuit may be defective. TROUBLESHOOTING HINTS (The most likely causes for this case:)
Damaged wiring harness or connector Malfunction of the steering wheel sensor
DIAGNOSIS Required Special Tools:

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:
