Circuit Test Oo
- Code 14 Displayed. This code indicates that 2 successive erratic Profile Ignition Pick-Up (PIP) pulses were sent to ECA, causing possible engine miss or stall. Check EEC-IV and TFI ignition system for loose wires and connections, arcing secondary ignition components (coil, cap, wires, etc.), or an on-board 2-way radio. Make sure radio antenna and power leads are routed properly. If any of the above conditions are present, repair as necessary and repeat QUICK TEST . If none are present, go to next step.
- Turn key off and wait 10 seconds. Deactivate SELF-TEST. Using CONTINUOUS MONITOR (WIGGLE) TEST , observe VOM or STAR tester LED for indication of fault while lightly tapping on TFI ignition module and distributor, and while wiggling TFI harness connector. If fault is indicated, disconnect and inspect connectors and terminals. If connectors and terminals are okay, diagnose TFI ignition system. If no fault is indicated, go to next step.
- While in CONTINUOUS MONITOR (WIGGLE) TEST , observe VOM or STAR tester LED for fault while wiggling, shaking, or bending small sections of harness from TFI module to firewall. Also check harness from firewall to ECA. Isolate PIP circuit, if required. If fault is indicated, isolate and repair problem and repeat QUICK TEST . If no fault indicated, go to next step.
- Turn key off and wait 10 seconds. Disconnect ECA 60-pin connector. Inspect connectors and terminals for damage. If connectors and terminals are okay, fault cannot be duplicated at this time. Diagnose TFI ignition system. If connectors and terminals are damaged, repair as necessary and repeat QUICK TEST .
