Type of gearbox | Test condition | Test/operation | Judgment value | Check item | Fault code | Inspection procedure if there is an abnormality |
4A/T | Selector lever in position D (Must be done on a level and straight road). | 1. Accelerate to 4th range at an accelerator pedal position sensor (APS) output of 1.5 V (opening angle 20%). | Data list no. 8 (speed sensor output shaft), 29 (accelerator pedal position). The shifting points correspond with the diagnostic tool display and the APS voltage (opening angle) and output shaft. | Problem during shifting. | Shocks, engine racing. | |
2. Slowly decelerate and stop the vehicle. | Incorrect shift points | All points | ||||
3. Accelerate to 4th range at an accelerator pedal position sensor (APS) output of 2.5 V (opening angle 50%). | Some points | |||||
No shifting | No fault codes stored. | |||||
