Quick Test: Description

The QUICK TEST diagnostic procedure is a functional test of the EEC system. It consists of 6 basic test steps. These basic steps must be carefully followed in sequence, otherwise misdiagnosis, or replacement of non-faulty components may result. The QUICK TEST procedures should be used only when you are directed here by the DIAGNOSTIC ROUTINES. Anytime a repair is made, the negative (-) battery cable should be disconnected and the brake pedal depressed for 5-10 seconds, then repeat the Self-Test sequence to ensure the repair was effective and no codes are present.

NOTE: Correct test results for system are dependent on the correct operation of several related non-EEC components and systems. All non-EEC problems in the engine, ignition or fuel system should be corrected before attempting to diagnose the EEC system.
