Tc TERMINAL CIRCUIT

Turn ignition on. Remove short pin from Data Link Connector No. 1 (DLC1). Connect jumper wire between terminals Tc and E1 of Data Link Connector No. 2 (DLC2) or DLC1. See Figure or Figure. If voltage is not 10-14 volts, check for open or short in harness and connector between ABS and TRAC ECU, TRAC ECU and DLC2 or DLC1, or DLC2 and DLC1 to body ground. If harness and connector are okay, check and replace TRAC ECU. If harness and connector are not okay, inspect TRAC indicator light circuit.
