Pinpoint Test K: The Stoplamps Are On Continuously: Notes
WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
Refer to OEM WIRING DIAGRAMS , Turn Signal/Stop/Hazard Lamps for additional information.
When the brake pedal is applied, the stoplamp switch routes voltage to the Smart Junction Box (SJB), the PCM and Body Control Module B (BCM-B). When the BCM-B detects the brake pedal is applied, the BCM-B provides voltage to the high mounted stoplamp and the LH/RH rear stoplamps.
DTC FAULT TRIGGER CONDITIONS
| DTC Description | Fault Trigger Conditions |
|---|---|
|
An on-demand DTC that sets when the SJB detects a short to voltage from brake pedal input circuit. |
|
A continuous and on-demand DTC that sets when the BCM-B detects a short to voltage from the high mounted stoplamp circuit. |
|
A continuous and on-demand DTC that sets when the BCM-B detects a short to voltage from the LH rear inboard stoplamp circuit. |
|
A continuous and on-demand DTC that sets when the BCM-B detects a short to voltage from the RH rear inboard stoplamp circuit. |
|
A continuous and on-demand DTC that sets when the BCM-B detects a short to voltage from the RH rear middle stoplamp circuit. |
|
A continuous and on-demand DTC that sets when the BCM-B detects a short to voltage from the RH rear middle stoplamp circuit. |
|
A continuous and on-demand DTC that sets when the BCM-B detects a short to voltage from the LH rear outboard stoplamp circuit. |
|
A continuous and on-demand DTC that sets when the BCM-B detects a short to voltage from the RH rear outboard stoplamp circuit. |
|
A continuous and on-demand DTC that sets when the BCM-B detects a short to voltage from the brake switch circuit. |
