this ID number came out of a E-250 5.4 99, F2UB-14A093-AB ,Five wire plug does this module have anything to do with the ABS system? and/or the loaded/ unload control module?

We have all new brakes on this van, does have the two solenoids located under the master cylinder for the ABS, we can not figure out why the brakes will not work properly

Thanks for any help with this

 

Do you know any of this stuff? I just copy and pasted it off a service cd. I can't find that part number.

Principles of Operation

The anti-lock brake control module receives wheel speed readings from both front wheel speed sensors and the rear differential speed sensor, and processes this information, along with other sensor inputs, to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth on the ABS sensor indicators as it passes through the wheel speed sensor's magnetic field.

The anti-lock brake control module continuously monitors and compares the rotational speed of each wheel speed sensor indicator and, when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper(s). This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS control module returns the solenoid valves to their normal position, and normal (base) braking resumes.

The ABS control module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS control module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the pump motor is turned on for approximately one-half second. Any malfunction of the ABS system will cause the ABS to shut off; however, normal power assisted braking remains.


Dynamic Rear Proportioning (DRP)

Vehicles with four wheel disc brakes are equipped with dynamic rear proportioning (DRP). The DRP system is integral to the anti-lock brake control module. The DRP maintains brake balance and maximizes brake efficiency for all loading configurations. DRP detects the onset of front versus rear slip imbalance and limits the rear pressure. If the rear slip significantly exceeds the front slip, the DRP system will reduce the rear pressure. If this condition occurs, the driver will feel a slight pulsation in the brake pedal. The DRP system will be disabled if one diagnostic trouble code (DTC) is set from condition 1 and condition 2 or condition 3, or if one DTC from condition 2 and condition 3, or if two or more DTCs are set from condition 1.

Condition one:

l C1095

l C1196

l C1200

l C1212

l C1216

Condition two:

l C1155

l C1158

l C1233

Condition three:

l C1145

l C1148

l C1234

If any DTCs are retrieved, GO to Inspection and Verification — NGS.

3. If the fault is not visually evident, connect New Generation STAR (NGS) Tester to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the NGS menu. If the NGS does not communicate with the vehicle:

l check that the program card is correctly installed.

l check the connections to the vehicle.

l check the ignition switch position.

4. If the NGS still does not communicate with the vehicle, refer to the New Generation STAR Tester manual.

5. Carry out the DATA LINK DIAGNOSTIC TEST. If the NGS responds with:

l CKT914, CKT915, or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to «Section 418-00».

l NO RESP/NOT EQUIP for anti-lock brake control module, go to Pinpoint Test A.

l SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the anti-lock brake control module.

6. If the DTCs retrieved are related to the concern, go to Anti-Lock Brake Control Module Diagnostic Trouble Code (DTC) Index to continue diagnostics.

7. If no DTCs related to the concern are retrieved, proceed to Symptom Chart.


Inspection and Verification — Drive Cycle Test

The drive cycle test can be used as a system evaluation test or repair verification test, or during diagnosis (for intermittent concerns).

For system evaluation, the customer may only have a general concern about the way the vehicle is braking. There may not be a clear system concern to troubleshoot. This test is designed to produce common system concern symptoms. Once a symptom is found, a symptom diagnostic procedure can be followed to repair the vehicle.

Always use this test after vehicle repairs because the anti-lock brake control module is unable to detect some system concerns unless the vehicle is driven under specific conditions. After completing the drive cycle test, carry out the self-test using New Generation STAR (NGS) Tester.

Note:
Wetting down the area where the stops are to be performed will aid in this test.

Note:
An assistant should be used to monitor the wheels during the ABS stop. Momentary lockup is permissible.

1. While driving the vehicle approximately 16 km/h (10 mph), depress the brake pedal hard enough to lock all four wheels.

2. Does one wheel lock consistently?

l If yes and the yellow ABS warning indicator is not illuminated, proceed to the Symptom Chart.

l If yes and the yellow ABS warning indicator is illuminated, retrieve and document DTCs. Proceed to Anti-Lock Brake Control Module Diagnostic Trouble Code (DTC) Index.

3. Note:
If the pump motor turns on and the vehicle pulls immediately, the front anti-lock brake sensor opposite the pull should be checked using the ABS Misfire, ABS Too Sensitive, ABS Fires On Normal Stop procedure from the Symptom Chart. If the pump motor turns on and the vehicle does not pull, the rear anti-lock brake sensors should be checked using the ABS Misfire, ABS Too Sensitive, ABS Fires On Normal Stop procedure from the Symptom Chart. If the pump motor does not turn on and the vehicle pulls immediately, the system should be checked using the Vehicle Pulls During Braking procedure from the Symptom Chart.

Note:
Turn off the windshield wipers.

While driving the vehicle approximately 32 km/h (20 mph), perform a light-to-medium (normal traffic) stop.

4. Does the pump motor turn on and are brake pedal pulsations felt at any time during the stop?

l If yes and the yellow ABS warning indicator is not illuminated, proceed to the Symptom Chart.

l If yes and the yellow ABS indicator does illuminate, retrieve and document DTCs. Proceed to Anti-Lock Brake Control Module Diagnostic Trouble Code (DTC) Index.

5. Clear continuous DTCs.

6. Start the vehicle and shift the transmission into low gear.

7. Allow the vehicle to creep forward at idle for at least 45 seconds.

8. Does the yellow ABS indicator illuminate?

l If yes, retrieve and document DTCs. Proceed to Anti-Lock Brake Control Module Diagnostic Trouble Code (DTC) Index.

9. Slowly accelerate to 40 km/h (25 mph). Let at least 45 seconds elapse before reaching 40 km/h (25 mph).

10. Does the yellow ABS warning indicator illuminate?

l If yes, retrieve and document DTCs. Proceed to Anti-Lock Brake Control Module Diagnostic Trouble Code (DTC) Index.

11. Has the customer concern been addressed and corrected by the previous actions?

l If yes, the system is OK.

l If no, proceed to the Symptom Chart.

Thats some good info you dug up, but none of those symptoms are appearing with mine , but is a ford part #.

I was told that these vans have a device in them that will adjust the brake pressure according to the load in the back, it supposedly lessons the amount of brake pressure to the rears when it is loaded to keep the rear in place when in a panic/slippery stop.

I don't know if this is true or not

 

Well, we had an f250 company pickup, and I remember being under it and it had a valve looking thing that the brake lines connected to. The valve thing was mounted on a bracket, and there was a rod coming out of the valve that mounted to the rearend housing. It seemed like if the rearend twisted more or less when you hit the brakes, this would push the rod in or out of the valve more or less. But this truck was an early 90's, not newer like your van.

That cd says in 99 they had two abs systems. A rear only system, and a 4 wheel system. All that info in the other posts is for a 4 wheel system.

 

Thanks again, I'll beleive it has the rear ABS system. and i do remember the lever valve that your speaking of it wasnt much fun to stop your truck if you had awee bit too much of a load in it
