Diagnosis Procedure - Early Production

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 (connector side and harness side).
   • Harness connector E152
   • Harness connector M31

Is the inspection result normal?

YES

GO TO 2.

NO

Repair the terminal and connector.

1. Disconnect the following harness connectors.
   • ABS actuator and electric unit (control unit)
   • Harness connectors E152 and M31
2. Check the continuity between the ABS actuator and electric unit (control unit) harness connector and the harness connector.
   • For Mexico

     ABS actuator and electric unit (control unit) harness connector		Harness connector		Continuity
     Connector No.	Terminal No.	Connector No.	Terminal No.
     E125	25	E152	36G	Existed
     	15		35G	Existed

   • Except for Mexico

     ABS actuator and electric unit (control unit) harness connector		Harness connector		Continuity
     Connector No.	Terminal No.	Connector No.	Terminal No.
     E168	19	E152	36G	Existed
     	30		35G	Existed

Is the inspection result normal?

YES

GO TO 3.

NO

Repair the main line between the ABS actuator and electric unit (control unit) and the harness connector E152.

1. Disconnect the connector of 3CH CAN gateway.
2. Check the continuity between the harness connector and the 3CH CAN gateway harness connector.

   Harness connector		3CH CAN gateway harness connector		Continuity
   Connector No.	Terminal No.	Connector No.	Terminal No.
   M31	36G	M6	1	Existed
   	35G		2	Existed

Is the inspection result normal?

YES

Check CAN system type decision again.

YES

Error was detected in the main line between the ABS actuator and electric unit (control unit) and the 3CH CAN gateway.

NO

Repair the main line between the harness connector M31 and the 3CH CAN gateway.
