L110

Code L110 indicates the Body Control Module (BCM) has lost contact with the Left Switch Pod (LSP). This condition can be caused by a loss of ground or power to the LSP. Another cause is two opens, one in 928G, the other in 928H.

Notes on Trouble Trees
1. If you were not directed here from Chart A-1, then misdiagnosis could result.
2. If code B441 is also set, then a loss of voltage on circuit 840 is the cause.
3. This checks for voltage on circuit 840, the supply for the LSP.
4. This checks the data line for proper connection to the LSP.

Note on Intermittents
Check for poor connection of power, ground, and data circuits to the LSP. Return to "Lighting System Check."
