Test D: Flash Code 2 - Stoplamp Switch Circuit Failure

PINPOINT TEST D: FLASH CODE 2 - STOPLAMP SWITCH CIRCUIT FAILURE

D1-D3:

D3-D5:

D6:

Normal Operation
When the brake pedal and the clutch pedal (if equipped) are both released, a signal voltage from the speed control actuator routes to ground through the stoplamp switch. When the brake pedal is applied, voltage is routed to the speed control actuator through circuit CCB15 (BN/GN). This voltage signals the speed control actuator to disengage the speed control. When the clutch pedal (if equipped) is pressed, the clutch pedal position (CPP) switch opens, causing the speed control actuator to disengage the speed control.

Possible Causes
- Circuit 57 (BK) open
- Circuit CCB15 (BN/GN) open
- CPP switch
- Stoplamp switch
- Speed control actuator
