Volvo Repair: Reset Check Engine Light, volvo 850 glt, smog test
QuestionIs there an undocumented way to reset the Check Engine light on my Volvo 850 GLT?
I have a 1993 Volvo 850 GLT. My radiator failed last summer and I had my non-Volvo certified mechanic replace it. The Check Engine light has been on ever since. I've simply ignored it until now when I failed my smog test only because the Check Engine light is on. I haven't been able to find an inexpensive way to reset it, and all the dealers want ~$125+ to scan the codes and reset the light. I know that there is an OBD tool that costs ~$100, but I intend to sell this car in the next year and can't see spending that much money on a tool for one use.

AnswerBrandon, yes there is. Since its a 93, you can manually read the codes and clear the light. Where the washer bottle neck is, there are 2 small black boxes. Open #A and put the connector in #2. Turn key on and hold button for 10 seconds. Read codes. Example 1-2-1, etc. after the 3rd flash, hit the button again. If the same codes flashes, then hold the button for 5 or so seconds until the light is steady. Now hold for 10 seconds. Light should clear. you must read all the codes before it will clear. Do this on number 6 also. Roger
