Possible Causes
(L163) LEFT SIDEMARKER LAMP CONTROL CIRCUIT SHORTED TO GROUND
(L163) LEFT SIDEMARKER LAMP CONTROL CIRCUIT SHORTED TO VOLTAGE
TOTALLY INTEGRATED POWER MODULE

1. TEST FOR INTERMITTENT CONDITION

1.	Turn the ignition on.

2.	With the scan tool, clear all DTCs

3.	Turn the Left Turn Signal on.

4.	With the scan tool, read DTCs.

Does the scan tool display active: B17BF-LEFT SIDEMARKER LAMP CONTROL CIRCUIT OVERCURRENT?

Yes

The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

2. LEFT REAR TURN SIGNAL BULB

1.	Turn the ignition off.

2.	Remove Left Rear Turn Signal Bulb.

3.	Inspect the Left Rear Turn Signal Bulb.

Is the inoperative bulb OK?

Yes

Replace the Inoperative bulb in accordance with the Service Information.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

3. (L163) LEFT SIDEMARKER LAMP CONTROL CIRCUIT SHORT TO GROUND

1.	Disconnect the TIPM C4 harness connector.

2.	Disconnect the Left Sidemarker Lamp harness connector.

3.	Measure the resistance between ground and the (L163) Left Sidemarker Lamp Control circuit.

Is the resistance above 10k Ohms?

Yes

Repair the (L163) Left Sidemarker 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. (L163) LEFT SIDEMARKER LAMP CONTROL CIRCUIT SHORTED TO VOLTAGE

1.	Turn the ignition on.

2.	Measure for voltage on the (L163) Left Sidemarker Lamp Control circuit.

Is there any voltage present?

Yes

Repair the (L163) Left Sidemarker Lamp Control circuit short to voltage.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

Replace the Totally Integrated Power Module (TIPM) in accordance with the Service Information.
