Circuit Description
The battery feed circuit, from the INADV POWER BUS/RAP fuse to the BCM, provides power for the interior lamps.
Conditions for Running the DTC
The voltage on the interior lamps feed circuit from the BCM must be between 9-16 volts.
Conditions for Setting the DTC
The BCM detects that the circuit from the INADV POWER BUS/RAP fuse to the BCM is less than 1 volt for longer than 300 milliseconds.
Action Taken When the DTC Sets
The BCM stores DTC B1339 in memory.
Conditions for Clearing the DTC
| • | A current DTC B1339 will clear if the BCM no longer detects the fault. |
| • | A history DTC B1339 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present. |
