WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 1992 Ford Ranger, 1992 Ford RV Cutaway, 1992 Ford Pickup, 1992 Ford F-Super Duty, and 1992 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
Following test equipment is necessary to complete DIS ignition system tests.
- DIS Diagnostic Cable (Rotunda 007-00044)
- Spark Tester (Neon Bulb Type)
- Digital Volt-Ohmmeter (DVOM)
- Remote Starter Switch
- Breakout Box (BOB) With 2.3L DP DIS Overlay
- High Voltage Spark Tester (A spark plug with a broken side electrode is not sufficient to check for spark and may lead to incorrect results.)
- Tachometer
- Inductive Type Timing Light (DO NOT use "advance knob", if equipped, as it will not work correctly with DIS Ignition Systems.)
- Test Light (LED Type) Or Logic Probe (LED Type)
CAUTION:
A 12-volt incandescent (high voltage) test light SHOULD NOT be used to test CID or PIP circuit signals. It will load the circuit and may cause incorrect measurements or faulty DIS/ECA operations (engine stall).
