EEPROM error - Code 9009 - transmission reset not carried out/ EEPROM access error
Error cause
•
If the transmission has not been reset: the potentiometer reset or belt reset procedures have
not been successful or a new transmission ECU has been fitted without resetting the trans-
mission. If there is an EEPROM access error: the control unit cannot read or update the data
contained in the EEPROM. The transmission ECU should be replaced.
Troubleshooting
•
If the transmission has not been reset: the potentiometer reset or belt reset procedures have
not been successful, it is therefore necessary to try those operations again by means of the
diagnosis instrument, or a new transmission ECU has been fitted without resetting the
transmission. In case there is a yellow or black label OBD module, without 2006 legend, it
is consider normal that the error is displayed before the Potentiometer reset function, Phase
2, or the Belt replacement, Phase 2: it will no longer be displayed even after this second
phase has been carried out correctly.
•
If there is an EEPROM access error: replace the transmission ECU (see New control unit
activation procedure) and the belt.
Belt wear - Code 9011 - above maximum threshold
Error cause
•
Excessively worn belt: the second wear limit has also been exceeded. This implies the forced
setting of the transmission in automatic mode, RAIN setting.
Troubleshooting
•
It is necessary to replace the worn belt and in the future, before starting the engine, select
the Belt replacement or Belt replacement, Phase 1, and Belt replacement, Phase 2, function
(next, see Adjustable parameters).
