It further include the ECU controller being connect with measured piece gear position sensor, ECU controller is passed by mobile phone measured piece gear
The data of sensor are recorded and are monitored in real time to its measured piece gear position sensor state.
This test fixture is in use, and measured piece gear position sensor can automatic identification shelves by the position of perception electromagnet
Position (prior art) of the position in P gear, R gear, N gear or D gear, then measured piece gear position sensor exports corresponding data,
Computer by USBCAN card and cpu controller by CAN transceiver can automatic identification shift sensor output CAN message,
Cpu controller passes through the CAN message received and is controlled in four sub-circuits respectively after being identified corresponding status information
LED light is finally indicated with the indicator light of the different colours such as red blue Huang, is observed convenient for tester；And pass through closure key
Switch S1 can then simulate the press-key structure of existing shift assembly, keep off data output interface to the P on measured piece gear position sensor
The detection for carrying out direct-type not only solves the fatigue of tester by the use of this test fixture, also greatly improves
Working efficiency.
