Test 23, Check VRS Circuit For Short To Ground

With key off and ECA disconnected, disconnect EDIS module from EDIS module tee, leaving diagnostic cable connected to vehicle harness connector. Set DVOM to 2-k/ohm scale. Measure resistance between breakout box pins No. J48 (VRS E) and J7 (BAT -).

If resistance is less than 1025 ohms, repair short circuit. Remove all test equipment, and reconnect all components. Clear Continuous Memory, and check for fault codes. If resistance is greater than 1025 ohms, replace EDIS module. Remove all test equipment, and reconnect all components. Clear Continuous Memory, and check for fault codes.
