Escape 2WD V6-3.0L (2009)
-
Is the concern still present?
Yes
INSTALL a new SJB. TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
self-test.

Pinpoint Test K: The Stoplamps Are On Continuously
Refer to Wiring Diagram Set 90 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), 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 PCM and the
speed control actuator through circuit CCB08 (VT/WH). When the SJB detects the brake pedal is applied, the SJB provides voltage to the LH and RH
rear stoplamps through circuits CLS18 (GY/BN) and CLS19 (VT/OG), respectively. If equipped with trailer tow, voltage is also 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.
-
DTC B2045 (Left Rear Stop Lamp Circuit Open) - an on-demand DTC that sets when the SJB detects a short to voltage from the LH rear stop/turn
lamp voltage supply circuit.
-
DTC B2047 (Right Rear Stoplamp 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:
-
Wiring, terminals or connectors
-
Stoplamp switch
-
PCM
-
SJB
PINPOINT TEST K: THE STOPLAMPS ARE ON CONTINUOUSLY
-------------------------------------------------
K1 DETERMINE IF ALL THE STOPLAMPS ARE ILLUMINATED
-
Ignition OFF.
-
Observe the stoplamps with the brake pedal released.
-
Are all of the stoplamps illuminated?
Yes
GO to K3.
No
GO to K2.
-------------------------------------------------
K2 CHECK THE STOPLAMPS VOLTAGE SUPPLY CIRCUIT FOR A SHORT TO VOLTAGE
-
Disconnect: SJB C2280d.
-
Do the stoplamps continue to illuminate?
