Abstract

An electronic engine control system test analyzer using a basic test switching control box connectable to a standard digital volt/ohm meter or oscilloscope not just a special unit that a specific model and year car uses. It is a relatively small versatile test switching control box useable with substantially any modern day electronic engine control system. Adaptability from vehicle to vehicle electronic control system is accomplished via change of wire harnesses specific to each different vehicle system without changing the test switching control box. The test switching control box is a much less expensive unit than its counterpart dedicated to a specific make model and vintage vehicle and is in modular form that can be updated to greater numbers of test positions from time to time.

Claims

1. An electronic engine control system test analyzer in a system comprising:

a digital volt/ohm meter, an electronic engine control system;

a switching control box with connector means connectable to said digital volt/ohm meter, test connection switching means, and test indicator means; and

a switching control box to electronic engine control system interconnect wire harness specific to said electronic engine control system;

wherein said wire harness has a multi-contact connector connection with said control box, a multi-pin connector, and a multi-contact female socket connector in order that said wire harness interconnect a mating set of connectors in said electronic engine control system for testing thereof by said test analyzer;

wherein wire lines in said wire harness are connected to different wire lines interconnecting said multi-pin connector and said multi-contact female socket connector in said wire harness in providing wire harnesses for specific vehicle model electronic engine control systems interchangeably connectable to said switching box for individualized testing of respective specific vehicle model electronic engine control systems; and

wherein on overlay indicator panel is provided for the top of said switching control box consistent with the interconnect wire harness specific to a vehicle electronic engine control system being tested.

2. The electronic engine control system test analyzer of claim 1, wherein said test indicator means includes an engine an indicator and a self test indicator.

3. The electronic engine control system test analyzer of claim 2, wherein said test connection switching means includes a plurality of push button switches.

4. The electronic engine control system test analyzer of claim 3, wherein said test connection switching means includes a rotary switch.

5. The electronic engine control system test analyzer of claim 3, wherein said test connection switching means includes a plurality of rotary switches.

6. The electronic engine control system test analyzer of claim 3, wherein said test connection switching means also includes slide switch means.

7. The electronic engine control system test analyzer of claim 2, wherein said test connector means is a plurality of push button switches.

8. The electronic engine control system test analyzer of claim 1, wherein said test indicator means is a plurality of indicator lights.
