Circuit/System Verification

Observe the scan tool Front Fog Lamps Switch parameter while pressing and releasing the fog lamp switch. The parameter should cycle between Active and Inactive.
- If the parameter does cycle between the specified values, refer to FOG LAMP SWITCH CIRCUIT TEST .
With a test lamp connected to ground, probe each of the test points on the FOG Fuse while commanding the Fog Lamps ON and OFF with a scan tool. The test lamp should turn ON and OFF at one or both of the fuse test points when changing between commanded states.
- If the test lamp is always OFF, or remains always ON, refer to FOG LAMP PCB RELAY CIRCUIT TEST .
- If the test lamp turns ON and OFF, refer to FOG LAMPS CIRCUIT TEST
With the fog lamps ON, verify the fog lamp indicator is illuminated on the IPC.
- If the indicator does not illuminate, refer to FRONT FOG LAMP INDICATOR TEST .
