WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: The Flex Probe Kit must be used for all test connections. Use of standard multimeter probes may damage wiring terminals

B1 CHECK THE STOPLAMPS
- Apply the brake pedal while observing the stoplamps.
- Do the stoplamps illuminate?
Yes : GO to B2.

No : REFER to EXTERIOR LIGHTING to continue diagnosis of the stoplamps.
B2 CHECK ABS BOO INPUT CIRCUIT FOR AN OPEN
- Key in OFF position.
- Disconnect: ABS Module C135.
- Measure the voltage between ABS module C135-6, circuit CES09 (VT/OG), harness side and ground with the brake pedal released.
- Is the voltage greater than 10 volts?
Yes : GO to B3.

No : VERIFY BJB fuse 44 (15A) is OK. If OK, REPAIR circuit CES09 (VT/OG) for an open. CLEAR the DTCs. REPEAT the self-test.
B3 CHECK FOR CORRECT ABS MODULE OPERATION
- Disconnect the ABS module connector.
- Check for:
  - Corrosion.
  - Pushed-out pins.
  - Spread terminals.
- Connect the ABS module connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes : INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . CLEAR the DTCs. REPEAT the self-test.

No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
