368005 - J44 RIGHT DOOR MIRROR DEFROSTING NOT WORKING

the demisting function for the external rear view mirrors is controlled by the Driver's Door Node and the Passenger Door Node by the command coming from the Climate Node.The information concerning the timed demisting activation is made available by the Body Computer Node for the Door Nodes on the request of the Climate Node via the B-CAN.

STEP	OPERATIONS TO BE CARRIED OUT	TEST RESULTS
1	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Connect the Examiner diagnostic equipment to the diagnostic connect and check the following at the Passenger Door Node:In errors ambient that there are no faults	Move on to Step	Presence of faults	Continue following the instructions for the diagnostic equipment
2	COMPONENT CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Remove the rear view mirror and check the condition of the demisting resistance	Move on to Step	Demisting resistance broken	Replace the mirror See in Op. 7005R30 ELECTRICALLY operated DOOR MIRROR (one) - R.R.
3	DEMISTING EFFICIENCY CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Connect the Examiner diagnostic equipment to the diagnostic connector and carry out the demisting test and check the following using a multimeter at the Passenger Door Node in active diagnosis ambient:the presence of an earth and positive power suply (Wiring Diagram ) E3032 EXTERIOR MIRRORS ADJUSTMENT	Move on to Step	1. No positive supply	Move on to Step
		Move on to Step	2. No earth	Move on to Step
4	ELECTRICAL SYSTEM CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Remove the Passenger Door Node and check the continuity between the demister terminals and the Passenger Door Node (Wiring Diagram ) E3032 EXTERIOR MIRRORS ADJUSTMENT	Move on to Step	Electrical connection interrupted	Move on to Step
5	ELECTRICAL SYSTEM CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Remove the door panel and check: the continuity/insulation between the demister terminals and the rear view mirror connector the continuity/insulation between the rear view mirror connector and the Door Node (Wiring Diagram ) E3032 EXTERIOR MIRRORS ADJUSTMENT	Move on to Step	1. Electrical connection at rear view mirror broken	1. Replace the rear view mirror assembly See in Op. 7005R30 ELECTRICALLY operated DOOR MIRROR (one) - R.R.
		Move on to Step	2. Electrical connection between rear view mirror connector and Driver's Door Node broken	2. Restore the electrical connection. (Wiring Diagram ) E3032 EXTERIOR MIRRORS ADJUSTMENT
6	CHECK ON CORRECT OPERATION	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check that the fault is no longer present		Fault persists	Replace the Driver's Door Node
