Taurus FWD V6-3.5L (2008)
I13-I15
Test J: The Stoplamps Are On Continuously
PINPOINT TEST J: THE STOPLAMPS ARE ON CONTINUOUSLY
Normal Operation - Taurus, Taurus X
When the brake pedal is applied, the stoplamp switch routes voltage to the SJB, the PCM and the high mounted stoplamp through circuit CCB08
(VT/WH). The SJB then provides voltage to the LH and RH rear lamps through circuits CLS18 (GY/BN) and CLS19 (VT/OG), respectively.
Normal Operation - Sable

circuit CCB08 (VT/WH).
-
DTC B1485 (Brake Pedal Input Short to Battery) - is an on-demand DTC that sets when the SJB detects a short to voltage from the stoplamp
switch input circuit.
-
DTC B2045 (Left Rear Stop Lamp Circuit Open) - is an on-demand DTC that sets when the SJB detects a short to voltage on the LH rear stop/turn
lamp voltage supply circuit.
-
DTC B2047 (Right Rear Stop Lamp Circuit Open) - is an on-demand DTC that sets when the SJB detects a short to voltage on the RH rear
stop/turn lamp voltage supply circuit.
