Test 9, Check Pip Circuit For Short To Power

Measure resistance between J43 (PIP E) and J51 (VBAT E). If less than 5 ohms, PIP is shorted in harness. Check connectors, service or replace harness. Check for fault codes. See TESTS W/CODES article. If resistance exceeds 5 ohms, replace EDIS module and check for fault codes.
