1UZ-FE Posted July 13, 2004 Share Posted July 13, 2004 Im driving a 92 ls... that is 96 and later nope. you misread. Accessing Diagnostic Trouble Codes 96 & later are OBD2 systems. scroll down 1 page till you see: Without OBD2. OBD=On-Board Diagnostics. the very top of the page tells you step-by-step exactly how to retrieve error codes for a vehicle without OBD2. vehicles 96 and later all have OBD2 which can be accessed by a scan tool.

tansupplyman Posted July 14, 2004 Share Posted July 14, 2004 Not if you can see the engine light blink at you and can count!!!! Here is what the website said :: ""On pre-OBD II models, turn ignition to On, then use a jumper wire to connect terminals TE1 and El of the data link connector, located under the left hand side of the instrument panel. Codes are indicated by the number of flashes of the check engine warning light. Reading Trouble Codes If the ECU has detected a system malfunction, the check engine light will blink every .5 second. The first number of blinks will equal the first digit of a two digit diagnostic trouble code and after a 1.5 second pause, the second number of blinks will equal the second digit of same diagnostic trouble code. If there are two or more DTC's, there will be a 2.5 second pause between each. After all DTC's have been output there will be a 4.5 second pause and all DTC's will be repeated as long as the terminals TE1 and El of the data link connector are connected. In the event of two or more DTC's, indication will begin from smaller numbered code and continue in order to the larger. After all DTC have been recorded, remove jumper wire. Clearing Trouble Codes After service, the diagnostic trouble code or DTC's retained in the ECU memory must be cleared by remove the EFI fuse for approximately 10 seconds or more, depending on ambient temperature (the lower the temperature, the longer the fuse must be left out) with the ignition switch off. The OBD II scan tool has a feature to clear DTC's. Refer to the manufacturer's manual for procedures. DTC clearing can also be done by removing the battery ground cable, other memory systems (clock) will also be cleared. If the diagnostic trouble code is not cleared, it will be retained by the ECU and appear along with a new DTC in future trouble codes. If it is necessary to work on engine components requiring removal of the battery ground cable, confirm no DTC's are stored. After clearing codes, road test the vehicle to check that a normal operation. If the same diagnostic trouble code appears, the trouble has not been corrected.
