Test 27, Check Pip EEC Circuit For Short To VBAT

With key off, disconnect diagnostic cable connector from DIS module (Pins No. 1-6). See Figure. Connect LED test light between breakout box pins No. (+) J31 (PIP EEC) and (-) J60 (BAT -). Turn key on. If test light does not illuminate, go to next test. If test light illuminates, PIP EEC is shorted to BAT. Check connectors, repair or replace harness and check for fault codes. If vehicle still does not start, go to next test.
