INSTRUCTIONS

In the Protection and Switching Unit, check the 20 A permanent-supply fuse of the ECU, referenced "15". Check that the connector is clean and in good condition.

In the Protection and Switching Unit, check the 5 A after-ignition fuse of the ECU, referenced "5H". Check that the connector is clean and in good condition.

Replace them if necessary.

Engine speed zero, vehicle speed zero and selector lever in position "P" or "N".

If the solenoid valves are not energised, check:
  • the oil level in the gearbox,
  • that the ECU connector and the "modular connector" are clean and in good condition.

Repair if necessary.
Check the insulation, continuity and absence of parasitic resistance of the following links:

ECU pin 1 → Pin B3 of modular connector (+12 V)
ECU pin 10 → Pin B11 of modular connector (EVS 1)
ECU pin 9 → Pin B8 of modular connector (EVS 2)
ECU pin 7 → Pin B10 of modular connector (EVS 3)
ECU pin 8 → Pin B7 of modular connector (EVS 4)
ECU pin 13 → Pin B5 of modular connector (EVS 5)
ECU pin 14 → Pin B2 of modular connector (EVS 6)
ECU pin 26 → Pin B12 of modular connector (modulation solenoid valve)
ECU pin 20 → Pin B6 of modular connector (converter lock-up solenoid valve)
ECU pin 2 → Pin E2 of modular connector (EPDE)
ECU pin 12 → Pin E1 of modular connector (EPDE)

Repair if necessary.
If the fault persists, contact your Techline

AFTER REPAIR

Restart the conformity check from the beginning.

CLEARING

Before carrying out these erase commands, engine speed and vehicle speed must be zero and the selector lever must be in position "P" or "N".

  • RZ004 "Fault memory erase"

This command erases the current or stored faults of the automatic gearbox ECU.

  • RZ005 "Adaptive learning"

This command erases the adaptive learning values of the automatic gearbox ECU.

It is recommended to carry out a road test with the vehicle after this command, before returning the vehicle to the customer. After this command, the automatic transmission may show some malfunctions while the adaptive values are re-established.

  • RZ006 "Converter lock-up adaptive learning"

This command erases the adaptive learning values related to the converter.

After this command, it is recommended to carry out a road test with the vehicle before returning it to the customer. Automatic transmission operation may show some malfunctions while the converter-related adaptive values re-learn.

  • RZ007 "OBD Memory"

This command clears the OBD memory of the control unit.
