The battery positive voltage circuit, from the INADV POWER BUS/RAP fuse to the BCM, provides power for the interior lamps.
The voltage on the battery positive voltage circuit from the BCM must be between 9-16 volts.
The BCM detects that the battery positive voltage circuit from the INADV POWER BUS/RAP fuse to the BCM is less than 1 volt for longer than 300 milliseconds.
The BCM stores DTC B1339 in memory.
• | A current DTC clears when the malfunction is no longer present. |
• | A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction. |
