B0533

DTC B0532, B0533, or B0534

CIRCUIT DESCRIPTION
When the body control module (BCM) receives a left turn signal ON command from the turn signal switch, the BCM will apply voltage to the left rear stop/turn lamp supply voltage circuit and left turn signal lamps supply voltage circuit. The turn signal flasher is integrated within the BCM and will flash both circuits simultaneously. The turn signal indicator is also illuminated utilizing the left rear stop/turn lamp supply voltage circuit.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTCs:
- DTC B0532 Left Turn Signal Circuit Low
- DTC B0533 Left Turn Signal Circuit High
- DTC B0534 Left Turn Signal Circuit Open

CONDITIONS FOR RUNNING THE DTC
The battery voltage must be between 9-16 volts.

CONDITIONS FOR SETTING THE DTC
- When the BCM receives a left turn signal command and the left rear stop/turn lamp supply voltage circuit is open, shorted to ground, or shorted to voltage
- When the BCM receives a left turn signal command and the left turn signal lamps supply voltage circuit is shorted to ground or shorted to voltage

ACTION TAKEN WHEN THE DTC SETS
The left front and/or left rear turn signals 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 15:

The numbers below refer to the step numbers on the diagnostic table.
3. This step tests for supply voltage and ground at the inoperative bulb socket.
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.
12. After replacement of the instrument panel cluster (IPC), you must calibrate the new cluster for proper operation.
14. After replacement of the BCM, you must calibrate the new module for proper operation.
