Necessary Commissioning Routines for the Easytronic after Servicing/Repair (M20 MTA)

Note:   A number of different system components have to be replaced or repaired during vehicle repairs. To ensure that all the start up routines required for the Easytronic system are undertaken after a repair, the table below contains all the commissioning operations required.

The electronic control unit may only be removed and reinstalled once. If the electronic control unit is removed again, it must be replaced.

Notes for Service Situation

Note:   Basic measures with which it is essential to comply to guarantee optimum procedures during a repair:

• Obtain the version number of the most up to date TECH 2 software with the aid of Opel Service Information (TIS) and if this does not correspond to the software version number present in the diagnostic unit, perform a software update on the TECH 2 software using the TIS "Transfer diagnostic software" system.
• To compare the software version of the Easytronic control unit with the current one in the Opel Service Information (TIS) while carrying out a service or repairs, on TECH 2 select the "Read control unit ID" menu item from the "Additional functions" main menu. If a later Easytronic software version is present in the TIS, perform a software update on the Easytronic software using the TIS "Service Programming System (SPS)".
• After each service/repair situation, delete the fault memory of the Easytronic control unit and then undertake a test run. Then read out the fault memory again and rectify any fault still present.
• Do not fit the control unit from one vehicle into another, regardless of whether the vehicles are identical variants or not.

Parking the Vehicle

To prevent the vehicle rolling away, the handbrake must be on after parking.

Leaving the Vehicle

Do not leave the vehicle in gear and with the engine running. In this case a warning buzzer sounds when the driver's door opens.

Service Vehicle Soon (SVS)

The SVS warning lamp is triggered in the presence of some fault memory entries, which are activated by the Easytronic if a fault occurs. In this case it is still possible to drive the vehicle but a specialist garage should be found immediately to locate the fault and rectify it.

Brake Fluid for the MTA-Release System - DOT4+

The brake fluid for the release system must be changed at the specified intervals. It is essential that only the brake fluids specified by Opel/Marelli are used, namely "BASF Hydraulan 404 DOT4+" or "Shell Brake Fluid DOT4+ LW". Even slight contamination of the brake fluid with grease or oil (e.g. when grease is applied to the return line to assist connection or when the brake fluid has been topped up from a container contaminated with mineral oil) can result in failure of the master cylinder and thereby in failure of the clutch actuator and the central release.

Hydraulic Fluid for the MTA Hydraulic System - CS Speed Oil

The hydraulic fluid for the MTA hydraulic system is maintenance-free. It is essential that only the hydraulic fluid specified by Opel/Marelli is used, namely "Tutela CS Speed oil". Even slight contamination of the hydraulic fluid by grease or oil can result in failure of the MTA system.

Clutch Overheating

When stopping on a hill it is essential to put on the handbrake or to depress the footbrake. To avoid overheating/damaging the clutch, the vehicle should not be held stationary whilst in gear by increasing the engine revolutions. Even depressing the footbrake whilst simultaneously pressing the accelerator and with the car in gear leads to damage to the clutch and should not be undertaken.

Signal check via data list and additional data list

In order to carry out an analysis during the service it is necessary to read out various MTA-specific switches and signals using TECH 2.
