Note:
- When trouble codes appear (2WD models) No. 37, 38, 42, 61, 62 and 63 or (4WD models) No. 62, 63 indicator will flash immediately to warn the driver. However, a collision or impact may cause the indicator to stop flashing, but the fault codes will be stored in the memory of the automatic transmission control box until they are forced to be reset.
- The occurrence of DTCs No. 64 and 68 does not cause a warning flashing of the indicator.
- If the speed sensor fails, the fault code will not appear and the self-diagnosis system will not work. However, in position "O' selector movement will only occur in first gear, regardless of vehicle speed.
