Test NTC-13A - Checking Pcm Grounds & Power Circuit
WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect and inspect Powertrain Control Module (PCM) connector. Repair as necessary. Using scan tool in ohmmeter mode, check resistance of PCM connector terminal No. 5, signal ground circuit (Black/White wire). If resistance is more than 5 ohms, repair open in Black/White wire. Perform TEST VER-2.
- If resistance is less than 5 ohms, check resistance of PCM connector terminal No. 11, power ground circuit (Black/Tan wire), using scan tool. If resistance is more than 5 ohms, repair open in Black/Tan wire. Perform TEST VER-2.
- If resistance is less than 5 ohms, check resistance of PCM connector terminal No. 12, power ground circuit (Black/Tan wire), using scan tool. If resistance is more than 5 ohms, repair open in Black/Tan wire. Perform TEST VER-2.
- If resistance is less than 5 ohms, put scan tool in voltmeter mode. Turn ignition on. Using scan tool, check voltage on PCM connector terminal No. 9, ignition 12-volt feed circuit (Dark Blue/White wire). If voltage is less than 10 volts, repair open in Dark Blue wire, Dark Blue/White wire or Light Green/Black wire. Perform TEST VER-2.
- If voltage is more than 10 volts, turn ignition off. Reconnect PCM connector. PCM grounds and power circuits are okay. Test is compete.
