Diagnosis & Repair

Turn ignition on. Using voltmeter, check voltage between terminals Tc and E1 of DLC1 or Data Link Connector No. 2 (DLC2). See Figure. DLC1 is located on left side of engine compartment, near junction block. DLC2 is located under left side of instrument panel. If voltage is 10-14, circuit is okay. Connect a fused jumper wire or Service Connector (SST 09843-18020) between terminals Tc and E1 at DLC1 or DLC2. 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 circuits between ABS/TRAC ECU, DLC1 or DLC2, and between DLC1 or DLC2 and ground. Repair wiring as necessary. If wiring is okay, replace ABS/TRAC ECU.
