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

H1-H2:

H2-H4:

H4-H5:

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 1928 (RD/WH). The speed control deactivator switch (closed when the brake pedal is not applied) then routes the voltage to circuit 248 (TN/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.

Possible Causes
- Circuit 248 (TN/OG) short to voltage
- Circuit 1928 (RD/WH) open
- Speed control deactivator switch
- Speed control actuator
- SJB
