ABS system trouble.
Just replaced the front roters and brakes on the wifes 94 full size Bronco. When taking everything apart I noticed the automatic locking hubs were all rusted and broken. I replaced them with a manual set. I had to remove the tone rings from the old roters and install them on the new ones. While apart I cleaned the sensors. Now the ABS light comes on after driving about 25 feet.. I had no problem before I replaced the brakes, and roters. I tested both sensors with an Ohm meter. Both reading 1.07 ohms. Checked and made sure the toll rings were seated all the way to the stop. Took everything apart a second time. Cleand ring, sensors and checked wires. Everything looks normal. Truck stops ok as long as the ABS light is on, but system activates if attempting to stop before the ABS light comes on. Made the mistake of buying aftermarket roters. Should have bought OEM. Could someone tell me what to check next. How do I check the space between the sensor and the toll ring? Thank for any help.

The Hayes manual says to jump pins E and B on the test connector to get a trouble code via the ABS light. I located the test connector but there is no letter markings on it to tell me which pin is what letter., Thanks again for your reply. I want to make sure the problem is in the tone wheel or hub before I replace them again.

All Data says
NOTE: If 12V test light is not available, the Antilock warning light also flashes during this test.
Locate test connector in the engine compartment and install 12V test light between connector Pins 4 (Circuit 603 [DG]) and 2 (Circuit 57 [BK]) in test connector.
Key OFF. Connect a jumper wire between connector Pins 2 (Circuit 57 [BK]) and 5 (Circuit 606 [BK/LB]) in the test connector.
Key ON. Observe test light.
Remove jumper between connector Pins 2 (Circuit 57 [BK]) and 5 (Circuit 606 [BK/LB]) in the test connector after five seconds.
Count light flashes of test light or ABS warning light.
The DTCs are flashed out in most significant digit, then least significant digit. The digits are separated by 3-6 seconds and DTCs are separated by 15 seconds.
Example: The lamp flashes one time, pauses 3-6 seconds, flashes seven times, pauses 15 seconds, flashes six times, pauses 3-6 seconds, then flashes three times. DTCs output: 17 and 63.
Hope this will help

Southern Bronco, Thank You again for your help. I found what I thought was the test connector. A 7 wire plug with a cap on it. But I saw what you are talking about. The plug with the 10M bolt through the wire harness. I had it uncoupled but did not know where to go from there. I have a test light. I will get to it tomorrow. Again Thank you.

Disconnected the harness at the ABS brain. On the plug 57 is BK, but the BK/LB is 960. I jumped that and nothing happened. Light stays lit. I jumped the 57BK with 606 W/LB again the ABS light stays lit. It does not flash any codes. There is a test plug with a cap on it. It has 7 connectors. 3 on the top and 4 on the bottom. I do not see any plug with that configeration in the Hayes Book. Is there a possibility that the code clears when I turn the key to the off position. Thanks again for any help.
