Solenoid Valves Ground Circuit Continuity Test

  1. Turn ignition off. Remove jumper wire from previous test. Using an ohmmeter, check for continuity between ECU connector terminals No. 1 and 11. See Figure . If there is continuity, go to next step.
  2. If continuity does not exist, check for continuity between ECU connector terminal No. 1 and valve block housing and between hydraulic modulator and valve block housing. If continuity does not exist between ECU connector terminal No. 1 and valve block housing, repair wiring, and retest. If continuity does not exist between housings, repair as necessary.
  3. Reconnect jumper wire between ECU connector terminals No. 1 and 11. Check for continuity between ECU connector terminal No. 11 and valve block connector terminal No. 1 (Brown wire). See Figure and Figure thru Figure . If there is no continuity, repair wiring and retest.
