Notes :
•
While executing service routines, it is normal to see warning light(s) turning ON or error mes-
sages to be displayed on the instrument cluster screen. Everything will be back to normal when
the procedure is completed and the various systems have shut down.
•
While not mandatory, we strongly suggest clearing faults of all ECU’s before and after performing
a service routine. If you have faults currently stored that you would like to note, perform a read
fault prior to clearing.

Fault lists can be sent via Email. Please consult the read fault sec-
tion for more details.

Some service routines will not work if faults are stored in the ECU.
CAUTION
It is considered good practice to connect a power supply (Midtronic’s
PSC-550, CTEK MXS 25 or equivalent) to the battery when perfor
-
ming service routines. This will ensure that the battery voltage is suf-
ficient.
Note: Battery chargers are not suitable due to poor line regulation.
