1) Turn ignition off. Install BOB, leaving PCM disconnected. Turn ignition on. Measure voltage at BOB pin in question. Compare voltage to specification in PGC CIRCUIT PIN IDENTIFICATION table. If voltage is to specification, go to next step. If voltage is not to specification, repair wire in question.
2) Measure resistance between ground and BOB pin in question. If any measurement is greater than 5 ohms, repair associated wire to ground. If resistance is not greater than 5 ohms, return to PINPOINT TEST VREF if sent here from there, and temporarily substitute known good PCM. If not sent here from PINPOINT TEST VREF, return to diagnostic routine.
