5.9 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 as 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.
4. Read carefully and complete the requisites listed before
performing the gear learning function. And press OK after
completing the instructions shown
