Posted a few days ago about no power brakes on this vehicle. I have put in 2 new ABS Hydraulic Brake Boosters and they do not charge - always charged regularly when using brakes. Have checked 3 of the relays for abs -2 have 14V in and 14V out - 1 has 0 in and 0 out - the BAS system relay. Was told by tech on thios site this was a factory recall and take it to Chrysler for repair - found out it already had this recall 645. Something in the ABS system is not allowing the brake booster to charge - fuse etc, speed sensor do not know how to get abs error codes displayed.

Here's the testing and figures use a volt/ohm meter as described, codes need to be read with Chrsler DRB II scan tool.
NO RESPONSE Message 1. Disconnect Controller Anti-Lock Brake (CAB) 60-pin connector. Inspect connector for proper wire placement, corrosion, damaged terminals and pushed-out pins. Repair if necessary. 2. Select DRB-II in voltmeter mode. See DRB-II VOLT-OHMMETER Mode under DRB-II TEST FUNCTIONS. Probe terminal No. 60 of CAB 60-pin connector. See Fig. 4 . If voltage is at least 9 volts, go to next step. If voltage is not at least 9 volts, repair open in Dark Blue wire. 3. Place DRB-II in ohmmeter mode. See DRB-II VOLT-OHMMETER Mode under DRB-II TEST FUNCTIONS. Probe terminal No. 5 of CAB 60-pin connector. See Fig. 4 . If resistance is less than 10 ohms, go to next step. If resistance is 10 ohms or more, repair open Black (ground) wire. 4. Turn ignition off. Disconnect DRB-II from CCD data link connector. Inspect connector for proper wire placement, corrosion, damaged terminals or pushed out pins. Repair if necessary. 5. If data link connector is okay, use an external ohmmeter to check resistance at White/Violet wire terminal of CCD data link connector. See Fig. 5 . If resistance is greater than 10 ohms, go to next step. If resistance is 10 ohms or less, repair short circuit to ground in White/Violet wire. 6. Using an external ohmmeter, check resistance at Orange wire terminal of CCD data link connector. If resistance is greater than 10 ohms, go to next step. If resistance is 10 ohms or less, repair short circuit to ground in Orange wire. 7. Connect a jumper wire between chassis ground and terminals No. 11 and 12 of CAB 60-pin connector. See Fig. 4 . Use an external ohmmeter to check resistance at White/Violet wire terminal of CCD data link connector. If resistance is less than 10 ohms, go to next step. If resistance is 10 ohms or more, repair open White/Violet wire. 8. With jumper wire still connected, use an external ohmmeter to check resistance at Orange wire terminal of CCD data link connector. If resistance is less than 10 ohms, replace CAB. If resistance is 10 ohms or more, repair open Orange wire. Page 1 of 1 ANTI-LOCK - BENDIX-10 -1993 Chrysler Town & Country
