Normal Operation
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.
The ABS module uses internal pressure sensors to determine correct operation by monitoring internal Hydraulic Control Unit (HCU) hydraulic pressures. These DTCs set if the brake pressure sensor signals do not match. This fault could set by either an internal ABS module failure or an HCU pressure sensor failure. The pressure sensors are internal to the HCU and cannot be serviced separately.
DTC FAULT TRIGGER CONDITIONS
| DTC Description | Fault Trigger Conditions |
|---|---|
|
Sets in continuous memory if the brake pressure sensor signal is lower than expected. |
|
Sets in continuous memory if the brake pressure sensor signal is higher than expected. |
|
Sets in continuous memory if the brake pressure sensor signal is erratic or fluctuating abnormally. This fault could set by either an internal ABS module failure or a pressure sensor failure. |
|
Sets in continuous memory if the brake pressure sensor signal fails the internal accuracy check. |
|
Sets in continuous memory if the brake pressure sensor signals are not active. |
|
Sets in continuous memory if the master cylinder pressure exceeds the allowed limit after an ABS event. |
This pinpoint test is intended to diagnose the following:
- Stoplamp switch
- Brake pedal assembly
- ABS module
- HCU
