- Turn ignition off. Install BOB, leaving ECA disconnected. Turn ignition on. Measure voltage at BOB pin in question. Compare voltage to specification in PGC CIRCUIT PIN IDENTIFICATION table. If voltage is not to specification, repair wire in question.
- 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 less than 5 ohms, return to PINPOINT TEST VREF if sent here from there, and replace ECA. If not sent here from PINPOINT TEST VREF, return to diagnostic routine.
