Is there a way to reset the abs light. It is a friends truck and I have no idea why it came on changed the 4wal Kelsey hayes module already and the light is still on is it possible to reset it

possibly a faulty caliper

Check speed sensors on the front.Clean them with a non chlronated brake cleaner this most likely the problem.

Does your truck have ABS? If so you may have a bad brake
pressure modulator for the abs. Its the big box by the Master that says Kelsey-Hayes on it. You can pick up the complete unit from a salvage yard at a pretty reasonable price.

I also found this on another site. I know you said that you blead the Master but check this information out. The bleeding of a new Master Cylinder is very important to get it exactly right.

Check Brake fluid level.

When the ABS light is on, the brakes should revert to standard braking.

The only time ABS should invoke is when the tires are slipping as sensed by the wheel speed sensors when the wheel locks up on any of the axles.

ANTI-LOCK BRAKE SYSTEMS General Information Fig. 1: RWAL brake system diagram

There are two basic types of anti-lock systems available for this vehicle; a Rear Wheel Anti-Lock (RWAL) brake system and 4 Wheel Anti-Lock (4WAL) brake system. The 4WAL system has two variations; a 3 sensor system and a 4 sensor system. The 2WD vehicles will be equipped with the 3 sensor system, but the AWD vehicles can be equipped with either. The systems are easily identified by looking at the rear wheels for a sensor harness. If there is a sensor harness and thus, rear wheel sensors, it is the 4 sensor system. If the vehicle is not equipped with a harness, it is the 3 sensor system. The 4 sensor system takes it speed references from each of the wheels. The 3 sensor system takes its speed references from each of the front wheels and the vehicle speed sensor located in the transmission (2WD) or the transfer case (AWD). The RWAL system components consist of the Vehicle Speed Sensor (VSS), the Electronic Control Unit (ECU), the isolation/dump valve and the Vehicle Speed Sensor Buffer (also known as the Digital Ratio Adapter). The ECU also receives signals from various brake switches. The 4WAL system components consist of the Electro-Hydraulic Control Unit (ECHU) valve (also known as the Brake Pressure Modulator Valve or BPMV), the wheel speed sensors, Vehicle Speed Sensor (VSS) on 3 sensor systems and the VSS Buffer.

Both show as trans codes in my book. #73= Pressure Control Solenoid"If return amperage varies more than 0.16 amps from command amperage" and # 86 =Low Ratio, and this one has no definition. and they are listed under 96 disel W/4L80E and 94 gasW/4L60E.Well hope this helped.

HAve you troublesot the ABS?

One thing it DOES sound like is the power brake booster. The vacuum size has a leak.

YOUR VAN HAS THE KELSEY HAYES EBC5H UNIT.THIS IS ALSO USED ON CHRYSLER TRUCK + VANS .ALSO FORD USES THIS ABS BRAKE SYSTEM.IN ORDER TO BLEED THIS BRAKE SYSTEM YOU NEED A DRB 111 SCAN TOOL OR EQUIVALENT.THE SCAN TOOL HAS TO CYCLE THE HCU PUMP AND SOLENOIDS IN ORDER TO BLEED BRAKES.

The problem may be that the master cylinder needs to be bench bled,there is most likely air trapped in the piston of the master cylinder.The problem comes from the piston not being fully actuated when connected to the pedal assembly.A vacuum bleeder will generally pull it out.

Go to Module Master. I had the same problem sent mine in and came back. took less then 5 minutes to R/R. www.modulemaster.com

Prior to 2004, Durangos with 4 wheel ABS use the Kelsey Hayes Dodge controller attached to the hydraulic unit. Durangos with just rear wheel ABS use the Kelsey Hayes 125 located separately from the hydraulic unit.
2004 and later Durangos use the Bosch 5.4 controller.

Kelsey Hayes Dodge 1) Disconnect the negative battery cable.
2) Push the harness connector locks to release the locks, then remove the connectors from the CAB.
3) Disconnect the pump motor connector.
4) Remove screws attaching CAB to the HCU.
5) Remove the CAB.

Kelsey Hayes 125 1) Push the CAB harness connector lock to release the lock and remove the connector from the controller.
2) Remove the RWAL valve harness connector from the controller.
3) Remove the controller mounting screws and remove the controller from the mounting bracket.

Bosch 5.4 1) Pull out the side locking tab on the Bosch controller as shown.
2) Remove the connector.
3) Remove the 6 screws and separate the controller from the hydraulic unit.

TEST B: BATTERY VOLTAGE OUT OF RANGE - DTC B1676
1. Check if vehicle has been jump started within past 2 weeks. If vehicle has been jump started, ABS is
okay. If vehicle has not been jump started, go to next step.
2. Using DVOM, measure voltage between positive and negative battery terminals. If voltage is 9-19 volts,
go to next step. If voltage is not 9-19 volts, diagnose charging system. See appropriate GENERATORS
article in STARTING & CHARGING SYSTEMS.
3. Turn ignition off. Disconnect 25-pin ABS control module. Install EEC-IV 60-pin Breakout Box (014-
00322). Turn ignition on. Measure voltage between breakout box terminal No. 20 and ground. If voltage
is more than 10 volts, go to next step. If voltage is less than 10 volts, repair Light Blue/Pink wire between
ABS control module and instrument panel fuse panel.
4. Turn ignition off. Measure voltage between breakout box terminal No. 25 and ground. If voltage is
greater than 10 volts, go to next step. If voltage is less than 10 volts, repair Red wire between ABS
control module and power distribution box/engine compartment fuse box.
5. Measure voltage between breakout box terminal No. 9 and ground. If voltage is greater than 10 volts, go
to next step. If voltage is less than 10 volts, repair Yellow/Light Green wire between ABS control module
and power distribution box/engine compartment fuse box.
6. Measure resistance between breakout box terminal No. 8 and ground. Also, measure resistance between
breakout box terminal No. 24 and ground. If both resistance measurements are less than 5 ohms, replace
ABS control module and repeat self-test. If either resistance measurement is greater than 5 ohms, repair
suspect Black wire between ABS control module and ground distribution.
NOTE: DTC B1676 will set if vehicle has been jump started.
