id1002x2003800

Caution

•  Perform the following malfunction diagnosis only when it is diagnosed with a short to ground by CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

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.

Step	Inspection		Action
1	INSPECT FOR SHORT TO GROUND BETWEEN BODY CONTROL MODULE (BCM) AND CONNECTOR C-10 •  Switch the ignition off. •  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)]) •  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.
		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.
		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 [(E)].)
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.
		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.
		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.
		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.
		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.
		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.
		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 [(E)].)
