'04-09 Models

  1. Remove the gauge assembly (see GAUGE ASSEMBLY REPLACEMENT ).
  2. Inspect all the connectors and socket terminals to be sure they are all making good contact.
    • If the terminal are bent, loose, or corroded, repair them as necessary, and recheck the system.
    • If the terminals look OK, go to step  3.

  3. With the connectors connected, back probe the connectors and make these input tests.
    • If any test indicates a problem, find and correct the cause, then recheck the system.
    • If all the input tests prove OK, the gauge assembly must be faulty; replace it.
