Test TC-37B - Ignition Coil Primary Circuits
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

section. After each repair, perform TEST VER-2
.
- Turn ignition off. Disconnect Auto Shutdown (ASD) relay. Using an external ohmmeter, check resistance of Dark Green/Orange wire between ASD relay connector terminal "D" and ignition coil connector terminal No. 4. If resistance is more than 5 ohms, repair open Dark Green/Orange wire. If resistance is less than 5 ohms, go to next step.
- Turn ignition on. Using DRB in voltmeter mode, check voltage on ASD relay connector terminal "B" (Red/White wire). If voltage is less than 10 volts, repair open Red/White wire. If voltage is more than 10 volts, go to next step.
- Check voltage ASD relay connector terminal "A" (Dark Blue/White wire). If voltage is less than 10 volts, repair open Dark Blue/White wire. If voltage is more than 10 volts, go to next step.
- Turn ignition off. Disconnect fuel pump relay. Using an external ohmmeter, check resistance of Dark Blue/Yellow wire between ASD relay connector terminal "C" and fuel pump relay terminal "C". If resistance is more than 5 ohms, repair open Dark Blue/Yellow wire. If resistance is less than 5 ohms, replace ASD relay.
