Clearing Codes:

 

After you have repaired or replace any parts that you believe was the cause of the ECU error code, you will need to clear the code from the ECU.

 

1) Disconnect negative battery cable. Depress brake pedal for

at least 5 seconds. Reconnect battery cable.

2) Ground test connector with jumper wire. Turn ignition on,

but do not start engine for 6 seconds. Operate engine at 2000 RPM for

2 minutes. Verify no codes are displayed.
