Circuit/System Verification

Ignition ON, command the License Plate Lamps ON and OFF with a scan tool. The license plate lamps should turn ON and OFF when changing

between the commanded states.

Circuit/System Testing

1. Ignition OFF, disconnect the X902 inline harness connector.

2. Test for less than 10 ohm between the ground circuit terminal 15 and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Connect a test lamp between the control circuit terminal 1 and ground.

4. Ignition ON, command the license plate lamps ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between

the selected states.

瀚慖f the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the K9 BCM.

瀚慖f the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the K9 BCM.

5. If all circuits test normal, test or replace the E7L license plate lamp-left or E7R license plate lamp-right.
