Shifter CVT: Procedures
Shift Mechanism (Through VIN 8E_6A156499), Checking
Shift mechanism (through VIN 8E_6A156499), checking - 01J, Continuously Variable Transmission (CVT)
Overview:
^ 1. Selector mechanism function test
^ 2. Checking ignition key removal lock
^ 3. Locking button on selector lever handle, checking
-
If shift mechanism does not function as described, perform "Guided Fault Finding" with Vehicle Diagnosis, Testing and Information System VAS
5051B.
1. Selector mechanism function test
^
In selector lever positions "S", "D", "R" and "Tiptronic gate" the starter motor will not operate.
^
If selector lever position "N" is selected at speeds greater than 5 km/h, the selector lever lock solenoid must not engage and block selector lever.
Selector lever can be shifted into driving gear.
^
For speeds below 2 km/h (almost standstill) and shifting into selector lever position "N", the shift lock solenoid must only engage after approx. 1
second. Selector lever can only be shifted out of position "N" with brake pedal operated.
Selector lever in "P" position and ignition switched on:
-
Do not operate brake pedal.
^
Selector lever is locked and also cannot be shifted out of position "P" while locking button on selector lever handle is pressed. Shift Lock Solenoid
N110 blocks selector lever.
-
Press brake pedal and hold.
^
Shift Lock Solenoid N110 releases selector lever. It must be possible to select a driving mode without "hitching" while locking button on selector
lever handle is pressed.
^
Slowly shift selector lever from "P" through "R, N, D, S", checking whether Transmission Range (TR) Display Y6 in instrument cluster matches
selector lever position.
Selector lever in "N" position and ignition switched on:
-
Do not operate brake pedal.
^
Up to approx. 08.01: Selector lever is locked and cannot be shifted out of position "N" without pressing button on selector lever handle. Shift Lock
Solenoid N110 blocks selector lever.
^
As of approx. 08.01: Selector lever is not locked immediately when rapidly shifting through position "N" (e.g. from "R" to "D" ). This enables e.g.
"forward and reverse maneuvers" when vehicle is stuck. Shift lock engages when selector lever is located in "N" for longer than approx. 1 s with
brake not being pressed.
-
Operate brake pedal.
^
Shift Lock Solenoid N110 releases selector lever. It must be possible to select a driving mode without "hitching" while locking button on selector
lever handle is pressed.
Selector lever in position "D", ignition switched on:
-
Shift selector lever into "Tiptronic gate".
^
Brightening of "D" symbol must go out in selector mechanism cover and "+" and "-" symbols must light up.
^
The Transmission Range (TR) Display Y6 in instrument cluster must change from "PRND" to "654321" or (from VIN 8E_5400001) from
"PRNDS" to "7654321" when selector lever is shifted into "Tiptronic Gate".
