Reading measured value block; Display group number 004; "Checking solenoid valves whilst driving"
◆ The solenoid valves can be checked whilst 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 shifting 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 and are only con‐
trolled during gear shifts and displayed in zones 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". Then during the drive it can be shifted
progressively into position "D".
◆ The mechanical gear "M" is not always engaged. The control unit can engage this gear dependent upon the
driving situation. The lock-up clutch can be checked in display group number 005.
◆ V.A.G 1551 display zone 1 has 6 characters (0000 00) and is read as follows:
