Diagnosis Procedure

CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the following terminals and connectors for damage, bend and loose connection (unit side and connector side).
  - Chassis control module
  - Harness connectors E47
  - Harness connectors M39
  - CAN gateway (Models with around view monitor system)
Is the inspection result normal?

YES - 1

Models with around view monitor system:GO TO STEP 2 .

YES - 2

Models without around view monitor system:GO TO STEP 3 .

NO

Repair the terminal and connector.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Disconnect the connector of CAN gateway.

Check the continuity between the CAN gateway harness connector terminals.

CAN gateway harness connector			Continuity
Connector No.	Terminal No.
M24	4	6	Existed
	10	12	Existed

Is the inspection result normal?

YES

GO TO STEP 3 .

NO

Check the harness and repair the root cause (CAN communication circuit 2).

CHECK HARNESS FOR OPEN CIRCUIT

Connect the connector of CAN gateway (Models with around view monitor system).
Disconnect the connector of chassis control module.

Check the resistance between the chassis control module harness connector terminals.

Chassis control module harness connector			Resistance (Ω)
Connector No.	Terminal No.
E22	4	3	Approx. 54 - 66

Is the measurement value within the specification?

YES

GO TO STEP 4 .

NO

Repair the chassis control module branch line.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the chassis control module. Refer to DIAGNOSIS PROCEDURE .

Is the inspection result normal?

YES (Present error)

Replace the chassis control module. Refer to REMOVAL AND INSTALLATION .

YES (Past error)

Error was detected in the chassis control module branch line.

NO

Repair the power supply and the ground circuit.
