B16B1 - Left Stop Lamp Control Circuit High

For a complete wiring diagram, refer to.

• When Monitored: Continuously.

• Set Condition: When the totally integrated power module detects a high condition.






Test Step 1 - Test For Intermittent Condition

• Turn the ignition ON.

• With the scan tool, clear all DTCs

• Turn the stop lamps ON.

• With the scan tool, read DTCs.

Does the scan tool display B16B1 - Left Stop Lamp Control Circuit High?

Yes

• Go to Test Step 2.

No

• The condition that caused this symptom is currently not present. Test 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 => Non-DTC Based Diagnostics. Body Interior

Test Step 2 - Test Ground Circuits

• Turn the ignition OFF.

• Disconnect the left rear tail lamp harness connector.

• With a test lamp connected to 12 volts, probe each ground circuit.

Does the test lamp illuminate brightly on each ground circuit?

Yes

• Go to Test Step 4.

No

• Go to Test Step 3.

Test Step 3 - Ground Circuit Open

• Measure the resistance of the appropriate ground circuits at the left rear tail lamp assembly harness connector.

Is the resistance less than 10.0 ohms?

Yes

• Replace the inoperative bulb. .

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

No

• Repair the appropriate ground circuits for an open.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Test Step 4 - Test Left Stop Lamp Control Circuit

• Turn the ignition ON.

• With the stop lamps still ON and a 12 volt test lamp connected to ground, test the left stop lamp control circuit.

Does the test lamp illuminate brightly?

Yes

• Replace the inoperative bulb. .

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

No

• Go to Test Step 5.

Test Step 5 - Left Stop Lamp Control Circuit Open

• Disconnect the TIPM C7 harness connector.

• Measure the resistance of the left rear turn signal control circuit between the left rear tail lamp harness connector and the TIPM harness connector.

Is the resistance less than 10.0 ohms?

Yes

• Go to Test Step 6.

No

• Repair the circuit for an open.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Test Step 6 - Left Stop Lamp Control Circuit Short to Voltage

• Turn the ignition ON.

• Measure for voltage on the left stop lamp control circuit.

Is there any voltage present?

Yes

• Repair the circuit for a short to voltage.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

No

• Replace the totally integrated power module.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
