Key OFF
Install a fuse in F115 in fuse box
Turn key to IGN (Do NOT START)
Digital display should show --:dlA or --dlA
Lift turn signal lever UP until display shows --ECU
Activate flash to pass.
Display should show 00 ECU
Move turnsignal lever UP once
If display alternates between 01:ECU and 00 ECU there are NO error codes to display

If you have errors the display will alternate between 01:ECU, 01:XXX, 01:End
XXX will be your three digit error code(s)
