WIRING DIAGRAM

INSPECTION PROCEDURE

NOTICE:
* Turn the engine switch off before measuring the resistance of CAN bus main wires and CAN bus branch wires.
* After the engine switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.
* Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the engine switch, any other switches, or the doors. If any doors need to be opened in order to check connectors, open the doors and leave them open.

HINT
Operating the engine switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change.

PROCEDURE

1. CHECK OPEN IN CAN NO. 1 BUS WIRE (ACTIVE CONTROL ENGINE MOUNT ECU BRANCH WIRE)

(a) Turn the engine switch off.

(b) Disconnect connector A9 from the active control engine mount ECU.

NG -- REPAIR OR REPLACE CAN NO. 1 BUS BRANCH WIRE OR CONNECTOR (ACTIVE CONTROL ENGINE MOUNT ECU)
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (IG2, GND)

(a) Measure the resistance according to the value(s) in the table below.

Standard resistance:

(b) Measure the voltage according to the value(s) in the table below.

Standard voltage:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE ACTIVE CONTROL ENGINE MOUNT ECU Removal
