TRAC Solenoid Relay

  1. Remove TRAC solenoid relay. Measure voltage between TRAC solenoid relay terminal No. 1 and body ground. If voltage is not 10-14 volts, check and repair harness or connector.
  2. Check continuity between TRAC solenoid relay terminal No. 2 and ABS/TRAC ECU terminals SAC, SMC and SRC. See TERMINAL IDENTIFICATION table. See Figure. If readings are not 2 ohms, replace TRAC solenoid relay.
