Test 32, Check VRS- Circuit For Short To Ground

With the key off, check the resistance between J48 (VRS- E) and J7 (BAT). If resistance is less than 5 ohms, service short circuit in VRS harness and check for fault codes. If resistance is greater than 5 ohms replace EDIS module and check for fault codes. See the appropriate TESTS W/CODES article.
