Envoy 2WD V6-4.3L VIN W (1998)
Outputs
Range: ON/ OFF
The rear fog lamp relay (export only) output refers to the commanded state of the rear fog lamp relay coil.
ON displays when the BCM commands the rear fog lamp relay coil to turn ON the relay, in order to power up the rear fog lamps.
OFF displays when the BCM does not command the rear fog lamp relay coil to turn ON. This denies current to the rear fog lamps and causes the rear fog
lamps to be kept OFF.
