Ts TERMINAL CIRCUIT

CAUTION: If Anti-Lock Brake System/Traction Control/Vehicle Skid Control Electronic Control Unit (ABS/TRAC/VSC ECU) replacement is necessary during testing, always ensure ABS/TRAC/VSC ECU connectors and ground circuit are okay. If either is suspect, repair and repeat testing to confirm ABS/TRAC/VSC ECU malfunction.

Turn ignition on. Check voltage between terminals Ts and E1 of Data Link Connector No. 1 (DLC1). See Figure. If battery voltage is present, circuit is okay (ABS/TRAC/VSC ECU may be faulty if light does not blink when connecting a jumper wire between terminals Ts and E1). If battery voltage is not present, check circuits between ABS/TRAC/VSC ECU and DLC1 and circuits between DLC1 and ground. See WIRING DIAGRAMS . If circuits are okay, replace ABS/TRAC/VSC ECU.
