Test TC-35A - Ignition Coil Primary Circuits (DTC 43)

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For circuit & connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY . For wiring diagrams, see WIRING DIAGRAMS section. After each repair, perform TEST VER-2 .

Using DRB, erase trouble codes. Attempt to start engine. If necessary, crank engine for at least 10 seconds. Read trouble codes. If DRB displays any IGNITION COIL PRIMARY CIRCUIT trouble codes, see IGNITION COIL PRIMARY CIRCUIT CODES table and perform corresponding test. If DRB does not display any injector control circuit codes, go to next step.

IGNITION COIL PRIMARY CIRCUIT CODES

DRB Display	Test No.
Ignition Coil #1 Primary Circuit	TC-35B
Ignition Coil #2 Primary Circuit	TC-36A
Ignition Coil #3 Primary Circuit	TC-37A

At this time, the condition required to set trouble code is not present. IGNITION COIL PRIMARY CIRCUIT trouble code sets when Powertrain Control Module (PCM) does not see peak current reached. Possible causes are: open or shorted ignition coil driver control circuit, open ignition coil primary circuit, open power supply, or failed PCM. Go to next step.
Inspect wiring and connectors. Repair as required. If wiring and connectors are okay, start engine. Wiggle wiring harness from Direct Ignition System (DIS) coil to PCM. If engine misses or stalls, repair wiring where wiggling caused problem to appear. If engine does not miss or stall, see INACTIVE TROUBLE CODE CONDITION . Test is complete.
