Gauge Control Module Input Test

NOTE: Before testing, do the gauge control module self-diagnostic function, and make sure the B-CAN communication line is OK.
  1. Turn the ignition switch to LOCK (0).
  1. Remove the gauge control module (A), and disconnect the 32P connector (B) from it.
  1. Inspect the connector and socket terminals to be sure they are all making good contact.
    • If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
    • If the terminals are OK, go to Step 4 .
  1. With the connector still disconnected, make these input tests at the connector.
