-
MB992110: Power Plant ECU Check Harness
STEP 1. Check the wiring harness between joint connector (CAN2) C-05 and steering wheel sensor connector C-211 for a short to ground.
Measure the resistance at joint connector (CAN2) C-05.
CAUTION:
-
Disconnect the negative battery terminal.
-
A digital multimeter should be used.
-
The test wiring harness should be used.
1. Disconnect joint connector (CAN2), and measure the resistance at the wiring harness side of joint connector (CAN2).
2. Measure the resistance between joint connector (CAN2) terminal 7 and body ground.
OK: 1 kohm or more
3. Measure the resistance between joint connector (CAN2) terminal 20 and body ground.
OK: 1 kohm or more
Q: Do all the resistances measure 1 kohm or more?
YES [Except RALLIART] : Go to Step 3.
