Test 28, Check VRS Bias At EDIS Module

With key off, disconnect the VR sensor from the EDIS diagnostic cable. Turn key on and check DC voltage between J35 (VRS+ E) and J7 (BAT-). If voltage is between 1.0 and 2.0 volts, replace VR sensor and check for fault codes. See TESTS W/CODES article. If voltage is not within specifications, go to TEST 29.
