Determination Procedure

CAUTION:

When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.
When inspecting the connector, touch it with a paper clip or similar thin pin without directly inserting a tester probe into the terminal.

DETERMINING SHORT TO GROUND LOCATION (CAN-BUS No. 6) (US) DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	INSPECT FOR SHORT TO GROUND BETWEEN BODY CONTROL MODULE (BCM) AND CONNECTOR C-08 Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US) .) Disconnect the connector C-10. Inspect for continuity at the following terminals: Between body control module (BCM) terminal 2A and body ground Between body control module (BCM) terminal 2C and body ground Is there continuity?	Yes	Go to the next step.
1		No	Go to Step 3.
2	INSPECT CAN LINE IN BODY CONTROL MODULE (BCM) FOR SHORT TO GROUND Disconnect the connector 2 which has body control module (BCM) terminals 2A and 2C. Inspect for continuity at the following terminals: Between body control module (BCM) terminal 2A (wiring harness side) and body ground Between body control module (BCM) terminal 2C (wiring harness side) and body ground Is there continuity?	Yes	Repair or replace the wiring harness between the connector C-10 and body control module (BCM) because the wiring harness is shorted to ground.
2		No	Replace the body control module (BCM) because there is a short to ground in the body control module (BCM). (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION .)
3	INSPECT FOR SHORT TO GROUND BETWEEN REAR SIDE RADAR SENSOR (LH) AND CONNECTOR C-10 Inspect for continuity at the following terminals: Between rear side radar sensor (LH) terminal C and body ground Between rear side radar sensor (LH) terminal D and body ground Is there continuity?	Yes	Go to the next step.
3		No	Go to Step 5.
4	INSPECT CAN LINE IN REAR SIDE RADAR SENSOR (LH) FOR SHORT TO GROUND Disconnect the rear side radar sensor (LH) connector. Inspect for continuity at the following terminals: Between rear side radar sensor (LH) terminal C (wiring harness side) and body ground Between rear side radar sensor (LH) terminal D (wiring harness side) and body ground Is there continuity?	Yes	Repair or replace the wiring harness between the rear side radar sensor (LH) and connector C-10 because the wiring harness is shorted to ground.
4		No	Replace the rear side radar sensor (LH) because there is a short to ground in the rear side radar sensor (LH). (See REAR SIDE RADAR SENSOR REMOVAL/INSTALLATION .)
5	INSPECT FOR SHORT TO GROUND BETWEEN FRONT RADAR SENSOR AND CONNECTOR C-10 Inspect for continuity at the following terminals: Between front radar sensor terminal E and body ground Between front radar sensor terminal C and body ground Is there continuity?	Yes	Go to the next step.
5		No	Go to Step 7.
6	INSPECT CAN LINE IN FRONT RADAR SENSOR FOR SHORT TO GROUND Disconnect the front radar sensor connector. Inspect for continuity at the following terminals: Between front radar sensor terminal E (wiring harness side) and body ground Between front radar sensor terminal C (wiring harness side) and body ground Is there continuity?	Yes	Repair or replace the wiring harness between the front radar sensor and connector C-10 because the wiring harness is shorted to ground.
6		No	Replace the front radar sensor because there is a short to ground in the front radar sensor. (See FRONT RADAR SENSOR REMOVAL/INSTALLATION .)
7	INSPECT FOR SHORT TO GROUND BETWEEN CONNECTOR C-10 AND CONNECTOR C-06 Disconnect the connector C-06. Connect the connector C-10. Inspect for continuity at the following terminals: Between body control module (BCM) terminal 2A and body ground Between body control module (BCM) terminal 2C and body ground Is there continuity?	Yes	Repair or replace the wiring harness between the connector C-10 and connector C-06 because the wiring harness is shorted to ground.
7		No	Go to the next step.
8	INSPECT CAN LINE IN BODY CONTROL MODULE (BCM) FOR SHORT TO GROUND Disconnect the body control module (BCM). Inspect for continuity at the following terminals: Between body control module (BCM) terminal 4N (wiring harness side) and body ground Between body control module (BCM) terminal 4M (wiring harness side) and body ground Is there continuity?	Yes	Repair or replace the wiring harness between the body control module (BCM) and connector C-06 because the wiring harness is shorted to ground.
8		No	Replace the body control module (BCM) because there is a short to ground in the body control module (BCM). (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION .)
