Normal Operation

The operating voltage required to operate the ABS module, hydraulic pump and isolation valves is in a range between 10 and 16 volts.

Fused battery voltage is supplied by Battery Junction Box (BJB) fuse 68 (60A) along circuit SBB68 (GN/RD) and by BJB  fuse 69 (60A) along circuit SBB69 (GY/RD). Fused ignition voltage is supplied by BJB  fuse 52 (10A) along circuit CBB52 (GN/WH). Ground is provided along circuit GD120 (BK/GN).

• DTC B1676 (Battery Pack Voltage Out of Range) - If the voltage to the ABS module is above 16 volts or below 10 volts, DTC B1676 will be set.

This pinpoint test is intended to diagnose the following: 

• Fuse(s)
• Wiring, terminals or connectors
• Charging system/vehicle battery
• ABS module
