The connector check must be accurately carried out before moving on to the next step.
Start the engine.
–Engage first gear and wait for the solenoid valves to be deactivated.
–Engage neutral, display the value of the parameters PR017 Engagement position and PR016 Selection
position and wait 10 seconds, checking that the values do not change.
–Switch off the engine and wait 15 seconds.
If, after waiting 15 seconds, it is impossible to push the vehicle, replace the engagement position sensor
(see MR 411 Mechanical, 21B, Sequential gearbox, Engagement sensor: Removal - Refitting).
–Start the engine.
–Engage second gear and wait for the solenoid valves to be deactivated.
–Engage neutral, display the value of the parameters PR017 and PR016 and wait 10 seconds, checking that
the values do not change.
–Switch off the engine and wait 15 seconds.
If, after waiting 15 seconds, it is impossible to push the vehicle, replace the engagement position sensor
(see MR 411 Mechanical, 21B, Sequential gearbox, Engagement sensor: Removal - Refitting).
