Test 26, Check VRS Resistance
With key off and ECA disconnected, connect EDIS diagnostic cable negative lead to negative battery terminal. Set DVOM to 20-k/ohm scale. Measure resistance between breakout box pins No. J48 (VRS E) and J35 (VRS+ E). If resistance is 2580-2700 ohms, go to next test. If resistance is not 2580-2700 ohms, go to TEST 28.
