Required commissioning routines for the Easytronic system for service/repair work (F13 MTA/F17+ MTA)

Note:   During vehicle repairs different system components have to be changed and repaired respectively. The following table lists the commissioning routines required after repair work so that all of the commissioning steps are carried out for the Easytronic system.

1. Changing the Easytronic control unit

• If an Easytronic service-control unit has been installed by aftersales service, the existing software has to be replaced in the service-control unit before commissioning. The software update is performed using the TIS 2000 "Service Programming System (SPS)" depending on the engine and/or vehicle type. The control unit is already locked Seed&Key.

2. Notes on servicing

Note:   Basic measures that should be taken into consideration when servicing to ensure optimisation of repair work:

• Obtain the version number of the most up to date TECH 2 software with the aid of Opel Service Information (TIS 2000) 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 2000 "Transfer diagnostic software" system.
• When servicing or carrying our repair work with the TECH 2 perform "Read Control Unit Identification" from the menu and compare the Easytronic control unit software version with the actual version in the Opel Service Information (TIS 2000). If a newer Easytronic software version is available in the TIS 2000, perform an update to the Easytronic software using the TIS 2000 "Service Programming System (SPS)".
• Delete the Easytronic error memory after each service/repair and perform a test drive. Then read out the error memory again and if necessary delete any remaining errors.
• The control units of two vehicles cannot be exchanged, irrespective of whether they are from similar or different vehicle variants. If this is necessary for test purposes it is essential to perform a commissioning cycle and to avoid a system function error and/or damaging the controls.

3. Possible error message and its remedy during initial use

The following error messages can appear in the TECH 2 display during initial use:

• Time out, check test conditions, transmission fault

Possible remedies:

• General
• Check battery voltage and connect battery charger if voltages of less than 12 V are present. If communication is interrupted during diagnosis, check connection between vehicle and TECH 2. Run through initial use menu for transmission several times.
• The battery must be connected directly to the original connections.

• If the error message time out or transmission fault appears
• Remove transmission actuator and check transmission. Can you shift gears? Do the shift forks align? Is the transmission in gear? Does the recess of the reverse gearshift rod align? Are the shift forks loose (transmission defect)? Check the seating of the ball grid of the end shield. Is the fifth gear roll pin present in the transmission housing?

• Check test conditions if there is an error message
• Disconnect hydraulic line from the MTA control unit and repeat test. If test is now OK, check clutch/release system, otherwise check fault memory entries and perform remedy in accordance with test instructions.

4. Parking the vehicle

To prevent the vehicle from rolling, the parking brake must be applied when the vehicle is parked.

5. Emergency clutch opening

• If the vehicle battery is discharged or there is a serious fault in the system, the clutch cannot be opened. If a gear is engaged at such a time, the vehicle cannot be moved. If the vehicle must be pushed away or moved out of the flow of traffic, the clutch can be opened. This emergency opening is only to be done in emergencies. Consult a workshop if emergency opening is used. When emergency opening the clutch, the ignition must be off and the foot brake must be depressed to prevent the vehicle from rolling away. Because the clutch actuator has no catch and the clutch can therefore close on its own, towing and starting are not permitted. An unfitted or incompletely fitted bearing cap could cause the brake actuator to malfunction. Do not switch on the ignition while the clutch is emergency opened as this could pose a danger or cause damage. The bearing cap must not be unintentionally pulled or twisted (no bracket). After emergency opening, a new bearing cap must be fitted.
• Additional information for mechanics to follow regarding emergency clutch opening can be found in operation "Emergency Clutch Opening (MTA)" .

6. Leaving the vehicle

Do not leave the vehicle if a gear is engaged or the engine is running. In such cases, a warning buzzer sounds when the driver's door is opened.

7. Service Vehicle Soon (SVS)

Some error memory entries generated by Easytronic in the event of an error result in activation of the SVS warning lamp. In such cases, continued driving is possible, but a workshop should be consulted immediately in order to have the error located and remedied.

8. Brake fluid for MTA release system

The brake fluid for the release system must be changed at the specified intervals. It is essential to use only Opel/LUK specified brake fluid "BASF Hydraulan 404 DOT4" or "Shell Brake Fluid DOT4 LW". Even minor contamination of the brake fluid by grease or oil (e.g. greasing a return line for easier attachment, or topping up brake fluid using a container which has been contaminated by mineral oil) causes a failure of the master cylinder and thereby a failure of the clutch actuator and the central release! Contamination in the system may be indicated by a swollen bellows in the compensation tank.

9. Clutch overheating

When holding on hills, pull the hand brake or actuate the foot brake! When in gear, do not keep the vehicle stationery by increasing the engine speed. This avoids overheating or damaging the clutch. Also, do not actuate at the foot brake while simultaneously actuating the accelerator pedal when in gear. This damages the clutch. The control unit activates, automatically and without driver warning, the clutch protection functions if an abuse situation is detected (e.g., the vehicle stalls).

10. Not OK criterion after contact point determination

After determining contact point using TECH2, an evaluation must be undertaken as to whether initial use was successful. The following not OK criterion applies:

• Vehicle type, after determining contact point 2
• Contact point >14.0 mm

If the not OK criterion is exceeded after contact point determination 2, topping up/bleeding and contact point determination must be repeated. Erratic engine torque signals or air in the hydraulic lines of the release system could generate this error profile. This not OK criterion is obtained empirically by means of production data evaluation and is similarly implemented in production plants. Increased coolant temperature negatively affects contact point determination or is evidence of incorrect contact point determination.

13. Signal check using 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.

There are 1 diagnostic data list and 2 additional data lists.

The signals and their value ranges are described in the test instructions and summarised in a snapshot data block which is displayed using the TECH 2 menu "Data list" and "Additional data list". See test instructions!

Note:   The work instructions for checking the desired values for the individual signals are listed in the TIS test instructions for the corresponding vehicle type. The signals of the "Additional data list" are intended for expanded diagnostics. In the TIS test instructions, no work instructions/desired of values are given for the signals contained in the additional data list. Checking the desired a value is shorted, for this reason, only be performed by personnel trained for the Easytronic.
