-
Enter the following diagnostic mode on the scan tool: SJB Self-Test.
-
Clear any DTCs and repeat the on-demand self-test (required to enable the stoplamp output driver if DTC B106E is present).
-
While applying the brake pedal, measure the voltage between the LH rear lamp C498-3, circuit CLS18 (GY/BN), harness side and ground; or
between the RH rear lamp C499-3, circuit CLS19 (VT/OG), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
REPAIR or INSTALL a new rear lamp jumper harness for a short to ground. CLEAR the DTCs. REPEAT the self-test. After the repair:
If no DTCs are present, TEST the system for normal operation.
If DTC B106E is present, CLEAR the DTCs and REPEAT the self-test (required to enable the stoplamp output driver if DTC B106E is present).
TEST the system for normal operation.
If DTC B106F is present, INSTALL a new SJB. REFER to Body Control Systems. TEST the system for normal operation.
No
GO to J12.

J12 CHECK THE REAR STOPLAMP VOLTAGE SUPPLY CIRCUIT FOR A SHORT TO GROUND
-
Ignition OFF.
-
Disconnect: SJB C2280d.
-
Measure the resistance between the SJB C2280d-25, circuit CLS18 (GY/BN), harness side and ground; or between the SJB C2280d-26, circuit
CLS19 (VT/OG), harness side and ground.
-
Is the resistance greater than 10,000 ohms?
Yes
GO to J13.
No
REPAIR circuit CLS18 (GY/BN) or circuit CLS19 (VT/OG) for a short to ground.
After the repair:
If no DTCs are present, TEST the system for normal operation.
If DTC B106E is present, CLEAR the DTCs and REPEAT the self-test (required to enable the stoplamp output driver if DTC B106E is present).
TEST the system for normal operation.
