Normal Operation
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The operating voltage required to supply the ABS module, hydraulic pump and isolation valves is in a range between 10 and 16 volts.
Fused battery voltage is supplied to the ABS module from Battery Junction Box (BJB) fuse 10 (30A) along circuit SBB10 (YE/RD) and fuse 8 (40A) along circuit SBB08 (VT/RD). Fused ignition voltage is supplied to the ABS module from Smart Junction Box (SJB) fuse 42 (10A) along CBP42 (GN) and ground is provided to the module along circuit GD123 (BK/GY).
- DTC B1676 (Battery Pack Voltage Out of Range) - If during normal operation, the vehicle battery voltage becomes less than 9.7 volts for more than 210 ms with vehicle speed greater than 20 km/h (12 mph), or the vehicle battery voltage becomes greater than 18 volts at any time, DTC B1676 will be set. Also, if during the ABS module self-test the vehicle battery voltage becomes higher than 18 volts, DTC B1676 will be set.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Charging system
- ABS module
