Test H: Flash Code 3 - Speed Control Deactivator Switch Circuit Failure

PINPOINT TEST H: FLASH CODE 3 - SPEED CONTROL DEACTIVATOR SWITCH CIRCUIT FAILURE

Normal Operation
Voltage for the speed control servo clutch (internal to the speed control actuator) is supplied by the smart junction box (SJB) to the speed control deactivator switch through circuit CBP34 (VT/BN) The speed control deactivator switch (closed when the brake pedal is not applied) then routes the voltage to circuit CES09 (VT/OG) to the speed control actuator. When the brake pedal is firmly pressed, the speed control deactivator switch opens and voltage is no longer supplied to the speed control servo clutch.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Speed control deactivator switch
- Speed control actuator
- SJB
