I have a 96 E-150 Club Wgn and I replaced the left front brake sensor Motorcraft # BREB63 because the sensor I replaced was not generating any AC voltage. I had disconnected the battery while replacing the sensor and was hoping that this would clear the ABS LIGHT. I have a scanner for engine codes but not for ABS. Does anyone know how to retrieve the code through the test port with a jumper without scanner? Many auto stores do not have
the scanner to test the 4WAB system.
Thanks!
Most places like Advance Auto use an Actron brand scanner----those will typically read ABS codes. That's of course assuming the user knows to prompt it to read them---they're not automatically displayed in the engine or powertrain diagnostic function.
FWIW I had an ABS issue that turned out to be the center rear differential speed sensor. When I replaced it the ABS warning dash light automatically reset itself. Connecting my Actron CP8590 I was able to confirm there were no further ABS codes.
I don't know of a way to test the individual sensors----to me they're either working or not.
I do know if there is a code for one showing in your scan its best to check each one's wiring path. Connectors can become corroded or lose conductivity making the ECM believe there's a problem. Typically any such issue will develop at the connector/interface closest to the road.
Within the OEM service manual I'm sure there are component tests for any sensor----I don't have one of those to access sorry to say.
To test a sensor first jack up the wheel for the sensor to be tested and disconnect the sensor wire connector and connect a digital voltmeter to the sensor lead. Turn the voltmeter to the AC Volts scale and while spinning the wheel a voltage should be generated possibly a half volt or more. If no voltage is
detected than the sensor may be defective. On limited slip differentials jack up
both wheels and always use jack stands and chocks to be safe.
I finally had a day above freezing and decided to change my front disc pads and
while I was at it I hooked up a volt meter to check the sensors. I used a
motor off a tread mill to rotate the wheels and the front left sensor generated
1.99 AC Volts the right front generated 1.89 AC Volts. I was unable to check the
rear sensor at the same day. I just purchased a Actron CP 9580A scanner off E-bay and as soon as I receive it, I'll will be able to diagnose the problem and replace the part that's defective.
That's a good scanner---be sure to use Actron's free firmware and library update service---adds a few more years and models to what's already on board.
That scanner has so far accurately diagnosed, identified and helped me through most ever CEL I've had.
I finally received the 9580A scanner however, it will not read the ABS on my
96 E150 either. I'm probably will keep the scanner as it will work on my other
vehicle. I will figure our the ABS problem when the weather breaks.
Thanks All!
