NOTE: For pin voltage charts on Passport, see Rodeo in Isuzu PIN VOLTAGE CHARTS article.

Pin voltage (value) charts are used for diagnosing intermittent symptoms and faults that are unable to be resolved during self-diagnostics. Pin voltage tests ensure Powertrain Control Module (PCM) is receiving and transmitting proper voltage and other signals. Before performing tests, ensure engine mechanical condition has been thoroughly inspected and self-diagnostics has been attempted. Available Technical Service Bulletins (TSBs) may also be helpful in correcting a hard to diagnose problem.
