Test Equipment

Following test equipment should be used in DI system tests.

  1. Spark Tester (D81P-6666-A Or D89P-6666-A)
  2. Digital Volt-Ohmmeter (DVOM)
  3. 12-Volt Test Light
  4. Remote Starter Switch
  5. EEC-IV Diagnostic Cable (007-00097)
  6. EEC-IV Breakout Box (T83L-50-EEC-IV)
  7. Inductive Timing Light

Diagnostic Aids

PINPOINT TESTS A, AA, AAA, B and C are intended to diagnose hard faults. Intermittent failures may be difficult to diagnose using these procedures. Following information should be noted during testing

  1. All voltage readings given in test procedures are based on values obtained using a standard DVOM such as Rotunda (007 -00001) or Fluke (20 or 70 Series). DO NOT use RMS type meter.
  2. When instructed to inspect a wiring harness, perform both a visual inspection and a continuity test.
  3. When making voltage checks, ground connections should be made at negative battery terminal or cast iron surface of engine.
  4. When making measurements on a wiring harness or connector, perform a wiggle test while measuring.
  5. When making voltage checks, ground readings are defined as a value of less than 1.0 volt. Battery voltage is defined as a value of more than 10 volts.
  6. Circuits are identified in all capitals, for example: PIP. Manufacturer's breakout box overlay test terminals are identified by a "J" prefix, for example: J15 (PIP). This indicates test terminal number and circuit identification. Probe models may not have a "J" designation in front of the test terminal number.
  7. Test procedures are intended to identify faulty components or wiring while fault is present. If complaint is an intermittent condition, see «TESTS W/O CODES - EEC-IV (2.0L)»(ref-22923) in the ENGINE PERFORMANCE section.

Note. Start all diagnostics with QUICK TEST. See TESTS W/CODES - EEC-IV (2.0L) article in the ENGINE PERFORMANCE section. These tests are dependent on results and diagnostic trouble codes received during QUICK TEST.
