Diagnosis & Repair

Turn ignition on. Using a voltmeter, check voltage between terminals Ts and E1 at DLC1 connector. See Figure. DLC1 is located on left side of engine compartment, near junction block. If voltage is 10-14 volts, circuit is okay. Connect a fused jumper wire or Service Connector (SST 09843-18020) between terminals Ts and E1 at DLC1 connector. Check ABS warning light. If ABS warning light does not blink, ABS/TRAC ECU may be faulty. If voltage is not 10-14 volts, check for open or short in wire harness circuits between ABS/TRAC ECU, DLC1 and between DLC1 and ground. Repair wiring as necessary. If wiring is okay, replace ABS/TRAC ECU.
