Test 24, Check Pip Circuit For Short To VBAT

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 1991 Ford Ranger, 1991 Ford RV Cutaway, 1991 Ford Pickup, 1991 Ford F-Super Duty, and 1991 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

Connect LED test light between breakout box pins No. (+) J33 (PIP S) and (-) J60 (BAT -). If test light does not illuminate, go to next test. If test light illuminates, PIP is shorted to VBAT between sensor and DIS connectors. Repair or replace harness. Check for fault codes. If vehicle still does not start, go to next test.
