B16B5-RIGHT STOP LAMP CONTROL CIRCUIT HIGH

For a complete wiring diagram, refer to the Wiring Information.

When Monitored:
Continuously.
Set Condition:
When the Totally Integrated Power Module (TIPM) detects a HIGH condition.

Possible Causes
CHECK (Z910) GROUND CIRCUIT
(Z910) GROUND CIRCUIT OPEN
CHECK (L54) RIGHT STOP LAMP CONTROL CIRCUIT
(L54) RIGHT STOP LAMP CONTROL CIRCUIT OPEN
(L54) RIGHT STOP LAMP CONTROL CIRCUIT SHORTED TO VOLTAGE
RIGHT STOP LAMP BULB
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 Stop Lamps on.

4.	With the scan tool, read DTCs.

Does the scan tool display active: B16B5-RIGHT STOP LAMP CONTROL CIRCUIT HIGH?

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. CHECK (Z910) GROUND CIRCUITS

1.	Disconnect the Right Rear Tail Lamp harness connector.

2.	With a 12-volt test light connected to 12-volts, probe each (Z910) Ground circuit.

Does the test light illuminate brightly on each ground circuit?

Yes

3. (Z910) GROUND CIRCUIT OPEN

1.	Measure the resistance of the appropriate (Z910) Ground circuit(s) at the Right Rear Tail Lamp assembly harness connector.

Is the resistance below 10.0 Ohms?

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).

Repair the appropriate (Z910) Ground circuit(s) for an open.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

4. CHECK (L54) RIGHT STOP LAMP CONTROL CIRCUIT

1.	Turn the ignition on.

2.	With the Stop Lamps still on and a 12-volt test light connected to ground, check the (L54) Right Stop Lamp Control circuit.

Does the test light illuminate brightly?

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).

5. (L54) RIGHT STOP LAMP CONTROL CIRCUIT OPEN

1.	Turn the ignition off.

2.	Disconnect the TIPM C7 connector.

3.	Measure the resistance of the (L54) Right Stop Lamp Control circuit between the Right Rear Tail Lamp harness connector and the TIPM C7 harness connector.

Is the resistance below 10.0 Ohms?

No

Yes

Repair the (L54) Right Stop Lamp Control circuit for an open.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

6. (L54) RIGHT STOP LAMP CONTROL CIRCUIT SHORTED TO VOLTAGE

1.	Turn the ignition on.

2.	Measure the voltage between (L54) Right Stop Lamp Control circuit and ground.

Is there any voltage present?

Yes

Repair the (L54) Right Stop Lamp Control circuit for a 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.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
