ABS at the starter relay

ANTI-LOCK BRAKE SYSTEM (and HCU-Hydraulic Control Unit)
General Information The 4-Wheel Anti-lock Brake System (ABS) is an electronically operated, all wheel brake control system. Major components include the power brake booster, master cylinder, the wheel speed sensors, and the Hydraulic Control Unit (HCU) which contains the control module, a relay, and the pressure control valves. The system is designed to ****** wheel lockup during periods of high wheel slip when braking. Retarding wheel lockup is accomplished by modulating fluid pressure to the wheel brake units. When the control module detects a variation in voltage across the wheel speed sensors, the ABS is activated. The control module opens and closes various valves located inside the HCU. These valves, called dump and isolation valves, modulate the hydraulic pressure to the wheels by applying and venting the pressure to the brake fluid circuits. Some models are equipped with a Traction Assist (TA) system. The TA system senses wheel spin upon acceleration, turns on the Hydraulic Control Unit (HCU) pump and applies fluid pressure to the appropriate rear wheel. Two additional isolation valves in the HCU will also close to permit fluid to flow only to the rear wheels. The TA system monitors TA usage to avoid overheating the rear brakes. If the system does sense brake overheating, the ABS module will inhibit TA operation until the rear brakes are permitted to cool down.

On 1992-1994 and 1995-00 a scanner is used to perform the brake bleed. But on yours, I think it's different according to the manual.

What do you mean change the cal. on the rear also? Do you mean Caliper?

just disconnect the ABS control module, the system will then default to standard brakes, you will however have a ABS warning light on all the time.

It is probably in the ignition controle module, this is a common problem with some modules. Once it gets hot it will cause the car to shut down. You can remove it and get it tested. It can be located in one of two locations on the bottom of distributor or on the driver side fender well.

you need a haynes repair manual it has your wiring diagram.

i removed a dash from an 89 mark VII, from a junkyard. it took me all day. so many things to dissconnect. move both seats as far back as possible and bring a lunch, you will need it. start on passenger side and work your way to the drivers side. while you have the dash out check the vent fan motor and ac evap.
