  2. If resistance is less than one ohm, replace pressure limit valve. If resistance is 1-3 ohms, disconnect RWAL EBCM connector. Measure resistance between EBCM harness connector terminal No. 9 and ground.
  3. If resistance is greater than 20,000 ohms, replace RWAL EBCM. If resistance is less than 20,000 ohms, repair short to ground in White/Green wire of harness.
