WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The longitudinal accelerometer is contained in the sensor cluster. The sensor cluster measures the vehicle acceleration and deceleration and then sends the signal over the controller area network (CAN) communication lines to the anti-lock brake system (ABS) module. Voltage is supplied by circuit 1576 (TN/BK). Ground is provided through circuit 1575 (BK/WH). The CAN communication is transmitted through circuit 1814 (WH/LB) and circuit 1815 (PK/LB).
Possible Causes
- Circuit open
- Circuit shorted
- Accelerometer/sensor cluster
- ABS module
