Volt

DTC B2699

When the headlamp switch is placed in dipped beam position, the body control module (BCM) applies a voltage to the headlamps through their respective voltage supply circuits.

B2699 01

The headlamps are turned OFF.

B2699 02 and B2699 04

The headlamps are turned ON.

B2699 01

The BCM detects a short to voltage on the control circuit.

B2699 02

The BCM detects a short to ground on the control circuit.

B2699 04

The BCM detects an open control circuit.

The right headlamp is inoperative.

The condition for setting the DTC is not longer present.

Vehicle in Service Mode, command the right Headlamp Dipped Beam test. The headlamps should be ON/OFF.

1. Vehicle OFF, disconnect the harness connector at the right headlamp.
2. Test for less than 5 Ω between the E13R Headlamp - Right ground circuit harness connector terminal 3 and ground.

⇒	If greater than the specified value, test the ground circuit for an open/high resistance.

3. Connect a test lamp between the E13R Headlamp - Right signal circuit harness connector terminal 2 and ground.
4. Command the Right Headlamp Low Beam test with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.

⇒	If the test lamp is always ON, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K9 Body Control Module.

⇒	If the test lamp is always OFF, test the Signal circuit for a short to ground or an open/high resistance. If the circuits test normal, replace the K9 Body Control Module.

5. If all the circuits test normal, replace the E13R Headlamp - Right.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
