You know the drill: What codes are you getting? ---

Hi Herwin! Thanks for your post. It may be time to stop clearing the codes and have the vehicle looked at by a mechanic. ---

> [@GorehamJ](#): > > It may be time to stop clearing the codes and have the vehicle looked at by a mechanic. +1 Merely clearing the codes without trying to fix the condition that led to the CEL lighting up is the automotive equivalent of touching-up x-rays. Diagnosis–and cure-- is going to be more difficult in both cases. ---

Clearing the codes just erases the problem from the ECU’s memory. It doesn’t fix the problem. The problem is still there. You need to get it fixed. ---

You’re saying the remote start failed? Was this a factory option, or did you have it installed by somebody else? They can cause problems. ---

Stop disconnecting the battery to erase codes. Can cause all kinds of problems. [https://www.aa1car.com/library/battery\_disconnect\_problems.htm](https://www.aa1car.com/library/battery_disconnect_problems.htm) Tester ---

Not to mention, the OP added extra risk by disconnecting the **positive** terminal.
