Where do I find the trouble codes on my OBD2?
Release the odometer buttons and read the trouble codes from the digital odometer. Locate the test port under the dash where the OBD2 scanner plugs in. Use a piece of jumper wire or even an unbent paper clip to link ports “A” and “B,” initiating the diagnostic sequence. Watch the “Check Engine” light for the codes to flash.
Can a jumper wire be used as a flash code?
Using a paper clip or a piece of wire as a jumper wire is PERFECTLY SAFE. Using jumper wires to flash codes has been built in by the car manufacturers to ensure people without a Scan Tool or Code Reader can still diagnose the vehicle faults by reading the codes.
What kind of meter do you use to read auto repair codes?
You can use any standard digital multimeter to read the codes. It can be a very low cost, simple meter. It only has to be able to measure 0 to 12 volts. You can use an Analog Voltmeter, however you need to make sure it has an internal resistance of at least 10K ohms to be safe.
