How to test the obd codes


What is year--make--model? Generally 94 model year and older is obd1. 96 and newer is obd2, generally. 95 can be a cross-over year and could have a hybrid diagnostic connector.

Usually with obd2, you need an obd2 code reader. OBD1 you should be able to access some codes, yourself, w/o a code reader. Different makes can have different procedures for accessing codes/obd1.

Volvo v70 abs light and mil light on. no coms with diagnostic socket, all fuses are ok. no 12v at diag socket, so no diag tools will work.


Are you plugging into the obd2 diagnostics port under the dash or the diagnostics port under the hood? You should be plugged in under the dash to read codes for the MIL / ABS light. Just a heads up as well most scanners you can buy from the part stores do not have the necessary program protocols to read European cars.

96 nissan 200sx is it obd2 ready


yes it has an obd2 diagnostic plug The trouble codes that are required by law on all OBD II systems are "generic" in the sense that all vehicle manufacturers use the same common code list and the same 16-pin diagnostic connector. Thus, a P0302 misfire code on a Nissan means the same thing on a Honda Toyota or Mercedes-Benz. But each vehicle manufacturer also has the freedom to add their own "enhanced" codes to provide even more detailed information about various faults

Diagnostic codes


the on off on off on method worked great on older chrysler vehicles, but its not reliable on the OBD2 systems.

all vehicles sold in the us as of 1996 are OBD2 compliant "on board diagnostics second generation" this is a universal system across all vehicles.

take your vehicle to your local parts store and ask them to scan it for you, most part stores wont even charge for the quick scan, dont let them erase the codes because there is other information in the system that will be useful for diagnostics.

get the code list and drop me a line and i will help you out.
