Reading measured value block; Display group number 004; Checking solenoid valves while driving, 01M, 4 Spd. A/T
Note:
^ The solenoid valves can be checked while driving via Read measured value block 08; display group number 004.
^ The table shows the solenoid valves -N88-, -N89- and -N90- (displays 1 to 3) as activated in each selector lever position. These solenoid valves control the shift valves for the relevant gears.
^ The solenoid valve -N91 - activates the lock-up clutch modulation valve and is not covered here.
^ The solenoid valves -N92- and -N94- are supplementary valves which affect gear shifts. These are only controlled during gear shifts and displayed in fields 5 and 6. They can show 0 or 1 depending on the driving situation.
^ At the start of a test drive the selector lever can be in position 1 During the drive it can be shifted progressively up to position D.
^ The mechanical gear M is not always engaged. The control module can engage this gear dependent upon the driving situation. The lock-up clutch can be checked in display group number 005.
^ VAG 1551 display field 1 has 6 characters (0000 00) and is read as follows:
