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 other switches or a door triggers related ECU and sensor communication on the CAN. This

communication will cause the resistance value to change.

* Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring

due to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may

help determine the cause of the malfunction.

PROCEDURE

1. RECONFIRM DTC OUTPUT

(a) Reconfirm DTCs.

HINT

If CAN MS bus DTC U1002 is output from the main body ECU (Techstream display/Main Body), troubleshoot for U1002 and

check for malfunctions in the CAN MS bus circuit.

Result:

B -- GO TO CIRCUITS INDICATED BY OUTPUT DTCS See: U1002

A -- Continue to next step.

2. CHECK CAN BUS WIRE FOR DISCONNECTION (OUTER MIRROR CONTROL ECU LH BRANCH WIRE)

(a) Turn the engine switch off.

(b) Disconnect the outer mirror control ECU LH connector.
