Pin Voltage Testing

Access PCM connector. See POWERTRAIN CONTROL MODULE LOCATIONS . If a breakout box is available, disconnect negative battery terminal. Connect breakout box to PCM harness connector and PCM. Reconnect negative battery cable. Take desired measurements between ground pin and specified pin on breakout box. See PID TESTING  under TEST PROCEDURES. If breakout box is not available, take desired measurements between ground pin and specified pin at PCM connector (backprobe PCM connector). See appropriate PIN VOLTAGE/PID VALUE TABLES  under PID DEFINITIONS & PIN VOLTAGE/PID VALUES.
