Test TC-35A - Ignition Coil #2 Primary Circuit (DTC 43)
WARNING: This page is about a different car, the 1995 Dodge Ram Wagon, 1995 Dodge Ram Van, 1995 Dodge Pickup, and 1995 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect ignition coil connector. Check connector for damaged or pushed-out terminals. Repair as necessary. Perform TEST VER-2. If connector is okay, go to next step.
- Turn ignition on. Using scan tool, actuate ignition coil No. 2. Using scan tool in voltmeter mode, check voltage on ignition coil connector, Auto Shutdown (ASD) output circuit (Dark Green/Orange wire). If voltage is less than 10 volts, repair open in Dark Green/Orange wire. Perform TEST VER-2.
- If voltage is more than 10 volts, using an external ohmmeter, check resistance of ignition coil No. 2 primary circuit. Put one ohmmeter lead on ignition coil connector, cylinders No. 2 and 5 pin, and other ohmmeter lead on ignition coil connector, battery positive pin. See Figure . If resistance is more than 2 ohms, replace ignition coil. Perform TEST VER-2.
- If resistance is less than 2 ohms, turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using scan tool in ohmmeter mode, check resistance of PCM connector terminal No. 17, ignition coil No. 2 driver circuit (Dark Blue/Tan wire). If resistance is less than 5 ohms, repair short to ground in Dark Blue/Tan wire. Perform TEST VER-2.
- If resistance is more than 5 ohms, using an external ohmmeter, check resistance of ignition coil driver circuit (Dark Blue/Tan wire) between ignition coil connector and PCM connector terminal No. 17. If resistance is more than 5 ohms, repair open in Dark Blue/Tan wire. Perform TEST VER-2. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2.
