Without Scan Tool
"ERASING" SELF-DIAGNOSIS RESULTS WITHOUT CONSULT
After a malfunction is repaired, switch the ignition "OFF" for at least one second, then back "ON". This causes the system to return to the "User Mode".
Alternately, you may use driver's door switch to return the system to user mode.
Note:
In User Mode the warning lamp will flash a warning only when there is a current problem. A trouble code identifying the problem will be stored in history. History codes may only be read with the warning lamp in diagnopstic mode. History codes may only be cleared using the scanner.
