Measure resistance of Blue/Orange wire between ground and FWWA wiring harness 6-pin connector. If resistance is less than 10,000 ohms, repair short to ground in Blue/Orange wire. If resistance is 10,000 ohms or more, go to next step.

  4. Measure resistance of Red wire between ground and FWWA wiring harness 6-pin connector. If resistance is less than 10,000 ohms, repair short to ground in Red wire. If resistance is 10,000 ohms or more, go to next step.
