Check VRS Resistance (NAVAJO)

Turn key off and disconnect ECA. 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 VRS SENSOR (NAVAJO). If resistance is not 2580-2700 ohms, repair wires between VRS and EDIS or replace VRS.
