GEAR LEARNING
The crankshaft position sensor learns crankshaft tooth machining tolerance and saves to the tablet to more
accurately diagnose engine misfires. If gear learning is not performed for a car equipped with a Delphi engine,
the MIL turns on after the engine is started. The diagnostic device detects the DTC P1336 'Gear not learned'.
In this case, you must use the diagnostic device to perform gear learning for the car. After gear learning is
successful, the MIL turns off. This function can complete the self-learning of the gearbox and improve the quality
of shifting.
After the engine ECU, crankshaft position sensor, or crankshaft flywheel is replaced, or the DTC 'gear not
learned' is present, gear learning must be performed.
The operation guidelines of the Gear learning function are shown below:
1.
Enter the Gear learning menu and choose relevant models according to the vehicle being tested.
2.
Turn on the ignition switch to start the vehicle.
3.
Enter the Tooth Learning menu.
Read carefully and complete the requisites listed before performing the gear learning function. And press OK
after completing the instructions shown
