TOTALLY INTEGRATED POWER MODULE

1. INTERMITTENT CONDITION

1.	Turn the ignition on.

2.	With the scan tool, clear all DTCs.

3.	Turn the Left Turn Signals on.

4.	With the scan tool, read DTCs.

3. (L53) LEFT STOP LAMP CONTROL CIRCUIT SHORT TO GROUND

1.	Disconnect the TIPM C7 harness connector.

2.	Disconnect the Left Stop Lamp harness connector.

3.	Measure the resistance between ground and the (L53) Left Stop Lamp Control circuit.

Is the resistance above 10k Ohms?

Yes

Repair the (L53) Left Stop Lamp Control circuit for a short to ground.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

4. (L53) LEFT STOP LAMP CONTROL CIRCUIT SHORTED TO VOLTAGE

1.	Turn the ignition on.

2.	Measure for voltage on the (L53) Left Stop Lamp Control circuit.

Is there any voltage present?

Yes

Repair the (L543) Left Stop Lamp Control circuit short to voltage.
