Test 29, Check VRS+ Circuit For Short To Power

With key off, disconnect the EDIS module from the EDIS diagnostic cable. Disconnect the HEGO sensor. Check the resistance between J35 (VRS+ E) and J51 (VBAT E). If the resistance is greater than 10 k/ohms, go to TEST 30. If resistance is less than 10 k/ohms, service short circuit in VRS+ harness and check for fault codes. See TESTS W/CODES article.
