Circuit/System Testing


Instrument Panel Compartment Lamp Circuit Malfunction

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.

4. Ignition ON, test for greater than 11 V between the 12 V reference circuit terminal 1 and ground.

5. If less than the specified value, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 Body Control Module.

6. If all circuits test normal, test or replace the E27 Instrument Panel Compartment Lamp.
