PINPOINT TEST 8: 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 (V/BR). The speed control deactivator switch (closed when the brake pedal is not applied) then routes the voltage to circuit (V/O) 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.

Possible Causes
- Fuse
- Wiring, terminals or connectors
- Speed control deactivator switch
- Speed control actuator
- SJB

Diagnostic Procedure

CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
