What Does C1182 Mean?
The park lamp flash relay circuit has an electrical failure. This relay controls the flashing of the parking lamps to visually confirm parking brake engagement or disengagement. The ABS or body control module cannot drive the relay properly. The driver will not see the parking light confirmation flash when operating the electronic parking brake, but this does not affect the actual braking function.
Common Causes
35%
Failed park lamp flash relay (stuck open or coil burned out)
25%
Open or damaged wiring between the control module and the relay
20%
Poor contact at the relay socket due to corrosion or terminal spread
15%
Blown fuse in the park lamp circuit
5%
Control module output driver failure
Diagnostic Steps
1
Locate the park lamp flash relay in the fuse/relay box (typically under the hood or in the driver's kick panel). Remove it and inspect the relay pins and socket for corrosion, burn marks, or melted plastic.
2
Test the relay on the bench: apply 12V and ground to the coil pins (85/86) and verify you hear a click and continuity across the contact pins (30/87). Replace if the relay does not switch.
3
Check the associated fuse for the park lamp circuit. A blown fuse indicates a downstream short that must be found before replacing the fuse.
4
With the relay removed, measure voltage at the relay socket control pin while commanding the parking brake. The module should pulse 12V or ground to the socket. If no voltage is present, check the wiring to the control module.
5
If the relay and wiring are good, verify the park lamp bulbs and their ground circuits are intact. A complete open in the lamp circuit can sometimes cause the module to report a relay fault.
