Circuit/System Verification

Ignition ON, observe the scan tool Exterior Driver Door Handle Proximity Sensor parameter while pressing and releasing the driver door handle

lock switch. The value should change between Active and Inactive as the switch is pressed and released.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the A24D Door Handle Assembly-Driver.

2. Ignition ON, verify the scan tool Exterior Driver Door Handle Proximity Sensor parameter is Inactive.

瀚慖f not the specified value, test the signal circuit terminal 3 for a short to ground. If the circuit tests normal, replace the K84 Keyless Entry

Control Module.

3. If all circuits test normal, test or replace the A24D Door Handle Assembly-Driver.

DTC Descriptor

DTC B2530 02

- Front Fog Lamps Control Circuit Short to Ground

Diagnostic Fault Information

Circuit/System Description

The front fog lamp relay is supplied with battery voltage at all times. The front fog lamp switch signal circuit is grounded momentarily by pressing

the front fog lamp switch. The body control module (BCM) energizes the front fog lamp relay by applying ground to the front fog lamp relay

control circuit. When the front fog lamp relay is energized, the relay switch contacts close and battery voltage is applied through the front fog lamp

fuse to the front fog lamp supply voltage circuit which illuminates the front fog lamps.
