Isuzu OBD1 Codes


Isuzu vehicles 1985-94 obd1 code retrieval

Isuzu OBD1 DecoderYou can get the check engine light codes yourself on 1985-94 Isuzu vehicles by using a jumper wire between terminal pins 1 and 3 or A and B in the diagnostic connector. This diagnostic connector can be located anywhere from the driver side kick panel, passenger kick panel and sometimes at the center console. When using A and B terminal pins, getting the codes is similar to GM vehicles. Once the jumper wire is connected, turn your key on and read the codes being flashed in the dash panel.
Reading the lights being flashed is simple, like code 12 is a long flash, a pause followed by 2 short flashes. Code 12 is also the first code to appear which verifies that the diagnostic system is working. If there are any codes that are present, it will be flashed in the same way with each codes being flashed 3 times before going to a next higher code.
Clearing the codes is done mostly by removing the battery negative terminal but removing the ecm (computer) fuse for 10 seconds is the best method. This way, you don’t need to re-program your radio or clock in case you use the battery connection.
Don't forget to remove the jumper wire with key off before clearing the codes.
