TROUBLESHOOTING HINTS
-
Malfunction of the connector [joint connector (CAN2) or steering wheel sensor connector improperly connected]
-

DIAGNOSIS
Required Special Tools:
-
MB991223: Harness Set
-
MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN2) C-104 and steering wheel sensor connector C-209 for loose, corroded or damaged terminals, or
terminals pushed back in the connector.
CAUTION: The strand end of the twisted wire should be within 10 cm (4 inches) from the connector.
Q: Are joint connector (CAN2) C-104 and steering wheel sensor connector C-209 in good condition?
YES : Go to Step 2.
NO : Repair the damaged parts.
STEP 2. Check the wiring harness between joint connector (CAN2) C-104 and steering wheel sensor connector C-209 for open circuit.
CAUTION: Strictly observe the specified wiring harness repair procedure.
1. Disconnect joint connector (CAN2) C-104 and steering wheel sensor connector C-209, and check the wiring harness.
