Test SC-5A - Checking Park/Neutral Switch Input

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION .

Unplug Powertrain Control Module (PCM) connector. Inspect connector. Clean and repair as necessary. Set gear selector in drive. With DRB in ohmmeter mode, measure resistance at PCM connector terminal No. 30 (Brown/Tracer wire for Cherokee or Black/White wire for Grand Cherokee).
If resistance is more than 5.0 ohms, replace park/neutral switch. Perform TEST VER-4A . If resistance is less than 5.0 ohms, repair short to ground in Brown/Tracer wire for Cherokee or Black/White wire for Grand Cherokee between park/neutral switch and PCM connector. Perform TEST VER-4A .
