Check the insulation, continuity and the absence of interference resistance on the following connections and
press the central door locking button to check the signal status on the following connections using the
oscilloscope (see signal status in test1 “Central door locking”):
●Connection code 64F between components 645 and 1391.
●Connection code 64Q between components 645 and 1391.
●Connection code 20M between components 1391 and 645.
●Connection code 20AW between components 1391 and 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
On component 1391, with the lock button pressed, check the continuity between connections 20AW and MAN.
On component 1391, with the lock button released, check the insulation between connections 20AW and MAN.
If the fault is still present, replace the central door locking/hazard warning lights switch (component code 1391).
