B0530

DTC B0530 (W/O RPO CW9)

Circuit Description

When the body control module (BCM) receives a right turn signal ON command from the turn signal switch, the BCM will apply voltage to the right turn signal indicator supply voltage circuit. The turn signal flasher, which is integrated within the BCM, will flash the right turn signal indicator lamp in the instrument panel cluster (IPC) simultaneously with the turn signal lamps.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC B0530 Right Turn Signal Circuit

Conditions for Running the DTC

The battery voltage must be between 9-16 volts.

Conditions for Setting the DTC

When the BCM receives a right turn signal command and the right turn signal indicator supply voltage circuit is open, shorted to ground, or shorted to voltage

Action Taken When the DTC Sets

The right turn signal indicator in the IPC will not operate or will remain always ON.

Conditions for Clearing the MIL/DTC

* This DTC will clear on current status after the condition for setting the fault is corrected.
* A history DTC will clear after 100 consecutive ignition cycles without a fault present.
* History and current DTCs can be cleared using a scan tool.

Test Description

Step 1 - Step 12:

The numbers below refer to the step numbers on the diagnostic table.
4. This step tests if battery positive voltage is constantly being applied to the supply voltage circuit.
5. This step tests if a condition exists in the supply voltage circuit.
6. This step tests if a condition exists in the ground circuit.
10. After replacement of the IPC, you must calibrate the new cluster for proper operation.
11. After replacement of the BCM, you must calibrate the new module for proper operation.
