Circuit/System Verification

Ignition ON, observe lamp of the instrument panel compartment lamp while opening the glove box. The lamp should illuminate when opened.

Circuit/System Testing
  1. Ignition OFF, disconnect the harness connector at the E27 Instrument Panel Compartment Lamp.
  2. Test for less than 5 Ω between the ground circuit terminal 2 and ground.
    3. ⇒If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, test for greater than 11 V between B+ circuit terminal 1 and ground.
    4. ⇒If less than the specified range, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 Body Control Module.
  4. If all circuits test normal, test or replace the E27 Instrument Panel Compartment Lamp.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
