Faulty component and down-grade performance table
The gearbox check control unit diagnosis, after ascertaining a fault takes action regarding the down-grade functioning. This data is indicated referring to the faulty component, in the table below:
|
FAULTY COMPONENT
|
Fault warning light
|
DOWN GRADING
|
|---|---|---|
| Gear engagement solenoid valves (proportional) | On | Gear shift acceptance locked, gear engagement excluding idle (N) (vehicle stationary) |
| Gear selection solenoid valve (ON/OFF) | On | Gear shift acceptance locked, gear engagement excluding idle (vehicle stationary) |
| Engagement and selection position sensors | On | Long time for gear shift.
Gear shift acceptance limited to 1, 2, R, N |
| Rev sensors: engine, gear input and gear output (car speed) | On | Gear shift acceptance limited to 1, 2, R, N |
