B2617

DTC B2617

CIRCUIT DESCRIPTION
The body control module (BCM) controls the I/P courtesy lamps through the courtesy lamps supply voltage circuit. The BCM grounds courtesy lamps low control circuit which completes the I/P courtesy lamps ground circuit, and the lights illuminate.

CONDITIONS FOR RUNNING THE DTC
The BCM must be commanding the courtesy lamps feature OFF.

CONDITIONS FOR SETTING THE DTC
- The BCM detects that the output for the courtesy lamps supply voltage circuit is low when it is expected to be high.
- The condition above must be present for more than 0.3 seconds.

ACTION TAKEN WHEN THE DTC SETS
The BCM stores DTC B2617 in memory.

CONDITIONS FOR CLEARING THE DTC
- A current DTC 2617 will clear if the short to ground or open in the courtesy lamps supply voltage circuit is no longer detected by the BCM.
- A history DTC B2617 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present nor any other malfunction in the BCM is detected.

DIAGNOSTIC AIDS
- If the DTC B2617 is a history DTC, the fault may be intermittent.
- The following conditions may cause an intermittent malfunction to occur:
- An intermittent short to ground or open in the courtesy lamps supply voltage circuit.
- Either I/P courtesy lamp is intermittently shorted to ground or open internally.
- The BCM is intermittently shorted to ground or open internally.
