B2608

CIRCUIT DESCRIPTION
The Body Control Module (BCM) illuminates RF turn signal lamp during Daytime Running Lamps operation in the day mode. The BCM applies steady power to the RF turn signal lamp which illuminates the RF turn lamp in a non flashing mode.

CONDITIONS FOR RUNNING THE DTC
The BCM must be commanding the RF turn signal lamp on.

CONDITIONS FOR SETTING THE DTC
^ The BCM detects a short to battery in the RF turn signal lamp circuit or the RF turn signal switch signal circuit.
^ The condition above must be present for more than 20 seconds.

ACTION TAKEN WHEN THE DTC SETS
The BCM stores DTC B2608 in memory.

CONDITIONS FOR CLEARING THE DTC
^ A current DTC B2608 will clear if the BCM no longer detects a short to battery in RF turn signal lamp control circuit.
^ A history DTC B2608 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
^ The BCM receives the Clear Code command from the scan tool.

DIAGNOSTIC AIDS
^ If the DTC B2608 is a history DTC, the fault may be intermittent. Refer to Testing for Intermittent and Poor Connections in Diagrams.
^ The following conditions may cause an intermittent malfunction to occur:
- An intermittent short to battery in the RF turn signal lamp control circuit or the RF turn signal switch signal circuit.
- The BCM is intermittently shorted to battery.

TEST DESCRIPTION

Steps 1-7:




The number(s) below refer to the step number(s) on the diagnostic table.
