Test 23, Check Pip Circuit For Short To Ground

With key off, disconnect diagnostic cable connector from crankshaft sensor. Disconnect diagnostic cable connector from DIS module (Pins No. 1-6). See Figure. Connect LED test light between breakout box pins No. (-) J33 (PIP S) and (+) J57 (BAT+). Turn key on.

If test light does not illuminate, go to next test. If test light illuminates, PIP is shorted to ground between sensor and DIS module. Check connectors, repair or replace harness and check for fault codes. If vehicle still does not start, go to next test.
