Condition
Some customers may comment on seeing any of multiple electrical issues, including but
not limited to:
• Dead battery
• Start/Stop inoperative
• Instrument cluster and switch backlighting remain illuminated
Cause
4977973
The cause of the condition may be that the wrong bulbs may have been installed in the
backup lamps. Incandescent bulbs (example shown above) should have been used, but
LED’s may have been incorrectly installed in their place.
Note: The BCM evaluates the Reverse Lamp circuit to determine bulb outages by
applying and monitoring a low voltage signal. Because LED lamps have different
electrical properties than Incandescent bulbs, the circuit does not operate as expected.
The BCM is calibrated for incandescent lamps and may stay awake after key off, if LED’s
are used. The BCM will continuously monitor the circuit, resulting in the symptoms
identified above.

Correction
4977978
On vehicles that exhibit the above conditions or other electrical abnormalities, check the
bulbs in the back up lamp locations.
• If the bulbs are found to be LED (1), the incorrect bulbs have been used and they
need to be replaced with Incandescent bulbs.
• If the bulbs are found to be the proper incandescent bulbs (2), refer to SI for further
diagnostic recommendations.
For backup bulb replacement, refer to the appropriate Backup Bulb Replacement
procedure below.
For Cadillac XT5 Models
4977982
1. Locate the backup lamp assembly underneath the
rear fascia.
2. Remove the bulb from the lamp assembly by
turning it counterclockwise and pulling straight out.
3. Remove the bulb and replace.
4. Reverse Steps 2 and 3 for assembly.
For GMC Acadia Models
4977986
Refer to Backup Bulb Replacement in SI.
