Pinpoint Test AN

  1. Verify condition by test driving vehicle above 5 mph and look for following:
    • Speedometer reading
    • Odometer changing
    • Speed control operation
  2. Check odometer by verifying that it advances when vehicle is driven forward. If odometer advances, replace speedometer module. If odometer does not advance, go to step 3.
  3. Check speed control. Did test drive verify speed control operation? If speed control works, go to step 4. If speed control does not work, service speed sensor circuit or speed sensor.
  4. Check resistance. Turn ignition switch off. Unplug 60-pin connectors from EEC module and Air Suspension Module. Remove EIC. Using an ohmmeter, measure resistance between C2-12 (Circuit 150 Dark Green/White wire) and C2-8 (Circuit 563 Orange/Yellow wire) of harness connector. Resistance should be 160-320 ohms If resistance is between 160 and 320 ohms, replace EIC. If resistance is less than 160 or greater than 320 ohms, service connectors, wiring Circuit 150.
