Check the connections of the brake pedal switch, the ABS computer, the electronic stability program
computer and the engine management computer.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V after ignition feed on the connections of the brake pedal switch connector and the
condition of the fuse.
– Connection code AP10 of component 160.
– Connection code SP13 of component 160.
Disconnect the ABS - ESP and check the continuity and insulation against + 12 V and against earth
of the following connection:
– Connection code 65A between components 160 and 1094.
Check that the brake pedal switch is working correctly:
in rest position: infinite resistance continuity between the following connections:
– Connection code 65A of component 160.
– Connection code AP10 of component 160.
depressed: continuity between the following connections:
– Connection code 65A of component 160.
– Connection code AP10 of component 160.
Replace the switch if necessary.
