•
Ignition switch connector C-307
•
Steering wheel sensor connector C-306
Check the connectors, for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Is the check result normal?
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-306
terminal 2 and ignition switch connector
C-307 terminal 2. Go to Step 8.
NO :
Repair or replace the damaged
component(s). Refer to GROUP 00, How to
Use Troubleshooting/Inspection Service
Points
− How to Cope with Intermittent
Malfunction
. Then go to Step 8.

STEP 3. Resistance measurement at steering
wheel sensor connector C-306.
(1) Disconnect the steering sensor connector C-306,
and measure at the harness side connector.
(2) Measure the resistance between terminal 5 and
body earth.
OK: 2 ohm or less
Q: Is the check result normal?
YES :
Go to Step 5.
NO :
Go to Step 4.
STEP 4. Check steering wheel sensor connector
C-306 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Is the check result normal?
YES :
