After several cases, the Chrysler automatic transmission must be set up: 1. battery pile head disassembly; 2. replacement battery; 3. replacement engine computer; 4. change automatic transmission computer; 5. replacement throttle body assembly; 6. set engine idle speed. Without setting up, the vehicle will enter the POWER-UP mode, and the vehicle will not be able to start. The contents of the automatic transmission system include the setting of anti-theft system, the setting of the transmission shift learning program, the gear ratio learning program setting, and the torque transmission clutch action setting. The setting methods and steps are described in detail below. 1. anti-theft system program set before connecting the battery, insert the door key in the driver's door lock, connect the battery and lock the door, then open the turning key once, the car can start. In the same mode, the buzzer should be rounded for 3 times to indicate that the anti-theft system is reset. Note: if you replace the engine computer, you must start the engine more than 20 times to make the anti-theft device reset. The 2. transmission shift learning program sets the transmission shift learning set to enable the transmission to learn the appropriate action, this action learning can be set using a diagnostic instrument. In the transmission shift learning setting, it must conform to the following states: 1. Brake well; 2. The engine speed must be higher than 500r/min; (3) the throttle opening is less than 3 degrees; 4. Shift control handle must be stopped at the specified gear in order to quickly hang into the overspeed gear. After completion of the training, the gear transmission should be stopped. The oil temperature of the transmission must be between 60~200 degrees. The shift learning program is as follows: 1. Connect the diagnostic instrument to the OBD- II 16pin fault diagnosis socket, the location of the fault diagnosis socket at the bottom of the cab dashboard; (2) the red / green light on the diagnostic instrument will light up and start to flicker until the flash stop is pressed (in the "SELECTSYSTEM" mode), and then press " The "2" button (in "TRANSMISSION" mode); (3) press the "1" key on the keyboard, wait until the diagnostic instrument performs the BUSTest, the start test (Initialize) and the transmission computer data test (TransmissionControl Module Part Number), and then continue the next step; (4) press on the keyboard. "5" key (ADJUSTMENTS), and then press the "3" button (QUICKLEARN), you can learn the action. When the transmission shift learning program is completed, the fault diagnosis socket is opened. 3. the gear must be compared with the learning setting after setting up the transmission computer after the learning program is set. If the step is not carried out, the speedometer will not work. The gear ratio learning program must be set up by using the original diagnostic instrument (OBD- III). The gear ratio learning program is as follows: 1. Connect the o b - III to the o b - II 16pin fault diagnosis socket; 2. The red and green lights on the diagnostic instrument will shine and flicker until the flicker stops, press the "4" key (in the "SELECTSYSTEM" mode), and then press the "2" key (in the "TRANSMISSION" mode) to enter the transmission Press the "1" button on the keyboard and wait until the diagnostic instrument performs BUSTest, Initialize Test and TransmissionControl Module Part Number (TransmissionControl Module Part Number), and then continues the next step; (4) press the "ADJUSTMENTS" on the keyboard to enter the tune. In the whole mode, press the "2" key (PINONFACTOR) to enter the gear than the learning mode, and then the gear ratio learning action can be carried out. When the gear is completed, the diagnostic instrument can be disassembled. The 4. torque transmission clutch action setting should be set when changing the torque transmission or ECM computer, and the torque transmission clutch should be set, and the OBD- III fault diagnosis instrument must be set. The action setting learning program of the torque transmission clutch is as follows: 1. Connect OBD- III to the OBD- II 16pin fault diagnosis socket. On the diagnostic instrument, the red and green lights flicker, and wait until the flicker stops, press the "4" key (in "SELECTSYSTEM" mode) to enter the system selection mode; 2. Second, press " The 2 "key (in" TRANSMISSION "mode) enters the transmission system, and then presses the" 1 "key on the keyboard until the diagnostic instrument performs the BUSTest, the starting test (Initialize Test) and the transmission computer data test (TransmissionControl Part Number), and then continue the next step; 3. Press the "ADJUSTMENTS" key (ADJUSTMENTS) on the keyboard to enter the adjustment mode, and then press the "RESETLUCLUTCH" key (RESETLUCLUTCH), the diagnostic instrument will appear the following information: *LU CLUTCH BREAK-IN STATUS:START (start) *LU CLUTCH BREAK-IN STATUS:PROGRESS (forward) *LU CLUTCH. 4 When the LU CLUTCH BREAK-INSTATUS:START is displayed, it indicates the start of the clutch action setting; when the LU CLUTCH BREAK-IN STATUS:PROGRESS or LU CLUTCHBREAK INSTATUS:COMPLETE is displayed, press the input key (ENTER) and return to the state of the start of the action setting; The input key (ENTER), the screen will appear RESET LU CLUTCHARE YOU SURE, and then press the input key (ENTER), that is, start the execution setting; when the BREAK-IN program is completed, the fault diagnosmeter will display the word (Break-inProcedure) completed.
