If DTC B106F is present, INSTALL a new SJB. REFER to Body Control Systems. TEST the system for normal operation.
-------------------------------------------------
J13 CHECK FOR CORRECT SJB OPERATION
-
Disconnect all the SJB connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the SJB connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?

Refer to Wiring Diagram Set 90, Turn Signal/Stop/Hazard Lamps for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
When the brake pedal is applied, the stoplamp switch routes voltage to the Smart Junction Box (SJB), the high mounted stoplamp, the Trailer Brake
Control (TBC) module (if equipped), and the PCM. When the SJB detects the brake pedal is applied, the SJB provides voltage to the LH and RH rear
stoplamp. If equipped with trailer tow, voltage is supplied to the respective trailer tow stop/turn relay.
-
DTC B1485 (Brake Pedal Input Short to Battery) - an on-demand DTC that sets when the SJB detects a short to voltage from the stoplamp switch
input circuit.
-

lamp voltage supply circuit.
-
DTC B2047 (Right Rear Stop Lamp Circuit Open) - an on-demand DTC that sets when the SJB detects a short to voltage from the RH rear
stop/turn lamp voltage supply circuit.
This pinpoint test is intended to diagnose the following:
-
