Where can I find an obd1 code scanner for an 1989 Mitsubishi Mirage?
You don’t need a code reader/scanner to pull the codes on a Mitsubishi OBDI system. But you do need an analog volt/ohm meter. This link explains how to pull the codes and the code definitions. http://www.extreme-check-engine-light-codes.com/Mitsubishi%20OBD1%20Decoder.htm
Thanks for your reply. I don’t want the code reader to pull the codes, I want it so I can look at all the sensor values while the engine is running.
The only way that’s going to happen is if you know someone who has a direct read-break-out box for the Mistubishi OBDI system. And I don’t even have that!
Snap-On MT2500 is probably your best and cheapest bet, as long as you can get one that has the proper cables for Mitsubishis of that era, and the cartridges to cover those cars (usually do have the cartridges, as one set of cartridges covers all Asian makes, if I remember correctly). If not, a Snap-On dealer can sell you what you need. The scanners can be found on eBay or on tool trucks for around $1500-2000 used. If you find one on a tool truck, buy it fast! Their cheap price tag and simplicity makes them very popular.
Probably your cheapest bet would be to find a wiring diagram for the vehicle and read the sensor signal off the wires. The wires will be color coded. If you can’t find a place where the signal is accessible, you can push a pin through the insulation on the wire. For analog signals (most of them I should think) you will want a high impedance (so as not to load the circuit) analog voltmeter or a cheap oscilloscope. There are Oscilloscope probes available for PCs for a few hundred dollars. I’ve never used one.
In my very limited experience, digital volt meters are cute and have a lot of digits. But they are virtually worthless for automotive or electronics troubleshooting.
