Normal Operation
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. 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 by Battery Junction Box (BJB) fuse 15 (40A) along circuit SBB15 (WH/RD) and BJB fuse 57 (40A) along circuit SBB57 (RD). Fused ignition voltage is supplied to the ABS module by BJB fuse 50 (10A) along circuit CBB50 (YE/OG). Ground is provided to the ABS module along circuit GD121 (BK/YE).
- DTC B1317 (Battery Voltage High) - If the voltage supplied to the ABS module exceeds 16 volts during the ABS module self-test or normal operation, with vehicle speed greater than 5 km/h (3 mph), DTC B1317 will be set.
- DTC B1318 (Battery Voltage Low) - If the voltage supplied to the ABS module falls below 10 volts during the ABS module self-test or normal operation, with vehicle speed greater than 5 km/h (3 mph), DTC B1318 will be set.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Vehicle charging system
- ABS module
