Diagnostic Procedure

Turn ignition to ON position. Measure voltage between terminals Ts and CG of DLC3. If voltage is 10-14 volts, circuit is okay. If ABS warning light does not flash even after terminals are connected, malfunction may exist in ABS ECU. If voltage is not 10-14 volts, check for open or short circuit in wiring harness between ABS ECU and DLC3, or between chassis ground and DLC3. See WIRING DIAGRAMS . Repair as necessary. If wiring harness is okay, replace ABS ECU. See ABS ECU/ACTUATOR  under REMOVAL & INSTALLATION.
