Checking Diagnostic Trouble Codes (DTC)
Not to be confused with the other thread in this section on using diagnostic mode.
Turn the key off for 30 seconds. Do the following within 5 seconds: Key ON, OFF, ON, OFF, ON (don't start the engine). Keep your eye on the CEL. The display will either say "Wait" and then the CEL will start blinking; or the CEL will start blinking right away. In either case, count the number of blinks between each long pause (b P bb P bbbb P b P bbbbbb P b). The codes are in two-digit numbers so the previous sequence would be 12, 41, 61. 12 = start and 61 = end. 12 may or may not happen.
This is a general list of codes. Different models and years may have slight variations.

To erase a code, remove the negative battery cable for 30 seconds. If they are still there after you hook the cable up and check again, that means they came right back.
