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 signal 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 supply voltage 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 supply voltage 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 a 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 supply voltage 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.
3. Tests for voltage at the turn signal lamp.
4. Test the turn signal supply voltage circuit for a short to voltage.
5. Test the turn signal switch signal circuit for a short to voltage.
