Test G: Flash Code 2 - Brake Pedal Position Switch Circuit Failure
- Press and release brake pedal while observing brakelights. If brakelights operate properly, go to next step. If brakelights do not operate properly, repair as necessary. See EXTERNAL LIGHTS article.
- Turn ignition switch to LOCK position. Disconnect speed control actuator 10-pin harness connector C122. Disconnect PCM 104-pin harness connector C175. Disconnect anti-lock brake control module 25-pin harness connector C155. Disconnect Brake Pedal Position (BPP) switch 2-pin harness connector C278. Measure resistance of Light Green wire between speed control actuator harness connector C122 terminal No. 4 and PCM harness connector C175 terminal No. 92, and between anti-lock brake control module harness connector C155 terminal No. 2 and BPP switch harness connector C278 terminal No. 1. See Figure , Figure and Figure . If resistance is less than 5 ohms in all measurements, replace speed control actuator. See SPEED CONTROL ACTUATOR under REMOVAL & INSTALLATION. If resistance is 5 ohms or more in any measurement, repair open or high resistance in appropriate Light Green wire.
