THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
AND CONTROL SECTION IN THE ELECTRICAL SYSTEM CHAPTER.
AXONE / AUTOMATIC TRANSMISSION system
PARAMETERS
Gear mode control
Example value: 3.8 V
Voltage detected at PIN B7: if the button is pressed, voltage drops from approximately 3-4 V to ap-
proximately 1 V.
STATUSES
Gear mode control
Example value:
Released/Pressed/Invalid data
If the "Invalid Data" message is displayed, it means that a malfunction has been detected
NOTE:
When troubleshooting, use the interface, code 020481Y, with the adaptor, code 020481Y004.
The correspondence between the control unit PIN and the interface PIN is the following: control unit
PIN A1….A8 and interface PIN interface 11….18, control unit PIN B1….B8 and interface PIN interface
21….28, control unit PIN C1….C8 and interface PIN interface 31….38
ERRORS
Gear mode switch - Code 9005
- above maximum threshold/ below minimum threshold.
Error cause
•
If above the maximum threshold: excessive voltage has been detected at PIN B7. If below
the minimum threshold: voltage equal to zero has been detected at PIN B7.
Troubleshooting
•
If above the maximum threshold: check circuit continuity between PIN B7 and C5: if it is not
OK, see Phase 1; if it is OK, check the transmission ECU connector and the gear mode
control connector and restore. Phase 1: check the continuity of the yellow/pink cable; if it is
not OK, restore; if it is OK, check for the interruption in the circuit of the gear mode control
and replace the component.
•
If below the minimum threshold: check the gear mode control resistance on its connector:
if the resistance is not within the expected limit values, replace the control; if it is within the
