Test 31, Check VRS- Circuit For Short To Power
With the key off, check the resistance between J48 (VRS- E) and J51 (VBAT E). If the resistance is greater than 10 k/ohms go to TEST 32. If the resistance is less than 10 k/ohms service short circuit in VRS- harness and check for fault codes. See the appropriate TESTS W/CODES article.
