STOREDBRAKE SWITCH 1 CIRCUIT
1.DEF : fault on one of the two brake pedal contacts
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present:
– with the engine running,
– With the brake pedal depressed,
– With cruise control ON.
Check that the pedal assembly is in good condition.
Check the cleanliness and condition of the dual-contact brake switch and its connections.
Repair if necessary.
Disconnect the battery.
Disconnect the computer. Check the cleanliness and condition of the connections.
Using the Universal bornier, check the insulation and continuity on the following connection:
Computer, connector A, track E4 Track 3 of the brake pedal
Repair if necessary.
If the fault is still present, replace the switch.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESPriority for dealing with a combination of faults:
Apply the procedure for dealing with fault DF127 Gang 1 switch circuit first if it is
present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present:
– with the engine running,
– With the brake pedal depressed,
– With the cruise control ON with a cruising speed set.
Run a multiplex network test (see88B, Multiplex).
If the fault is still present, run fault finding on the UCH system (see87A, UCH).
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
