DTC Fault Trigger Conditions
DTC |
Description |
Fault Trigger Condition |
BCM B1315:11 |
Backlighting (Non Reflective Controls) Illumination Output: Circuit Short To Ground |
This DTC sets in continuous memory and on-demand when the BCM detects
excessive current draw from the backlighting illumination output
circuit.
|
BCM B1315:15 |
Backlighting (Non Reflective Controls) Illumination Output: Circuit Short To Battery Or Open |
This DTC sets in continuous memory and on-demand when the BCM detects
lower than expected current draw from the backlighting illumination
output circuit.
|
Possible Sources
- Wiring, terminals or connectors
-
BCM
|
C1 CHECK THE EXTERIOR LIGHTING |
-
Place the headlamp switch in the OFF position.
-
Observe the parking lamps.
Are the parking lamps operating correctly?
Yes |
If the illumination is inoperative,GO to C3
If the illumination is always on,GO to C2
|
No |
DIAGNOSE a concern with the headlamp switch. REFER to: Headlamps (417-01 Exterior Lighting, Diagnosis and Testing).
|
|
C2 CHECK THE BCM (BODY CONTROL MODULE)ILLUMINATION OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE |
Do the non-networked components continue to illuminate?
|
C3 BYPASS THE BCM (BODY CONTROL MODULE)
|
-
NOTE:
If the jumper wire fuse fails during this step,

-
NOTE:
If the headlamp switch illumination is
inoperative, set the instrument panel and interior switch illumination
to the brightest setting with the ignition ON prior to disconnecting the
headlamp switch.
NOTE:
Anytime the EPB switch electrical connector is disconnected, the EPB
system is deactivated and a DTC is stored in the ABS module. To restore
the EPB system and clear the ABS module DTC
, apply and release the parking brake twice within 5 seconds. Pause
with the switch in the NEUTRAL position for approximately one-half
second between each apply and release.
Disconnect: Inoperative illuminated component
-
Place a shop light over the ambient light sensor and
make sure the backlighting illumination reaches maximum intensity.
-
Place the headlamp switch in the PARKING LAMPS or HEADLAMPS position.
-
