NOTESThere must be no present or stored faults.
The status displays "OPEN" with the pedal released and changes to "CLOSED" with the brake pedal depressed.
Check the cleanliness and the condition of the brake light switch connections.
Check the position, setting and correct operation of the brake light switch. (Watch out for the floor carpet which can
jam the switch.)
Disconnect the battery.
Disconnect the computer. Check the cleanliness and condition of the connections.
Use the Universal bornier Elé. 1681 to check the insulation, continuity and the absence of interference resistance
on the following connection:
●connection code 5A, between components 119 and 160.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the correct status is not displayed, replace the switch.
