| Items (CONSULT-III screen terms) | Malfunction is detected when | DTC (1) | Reference |
| "TRANSMISSION" with CONSULT-III | MIL (2) , "ENGINE" with CONSULT-III or GST |
| CAN COMM CIRCUIT | When TCM is not transmitting or receiving CAN communication signal for 2 seconds or more | U1000 | U1000 | |
| CONTROL UNIT (CAN) | When detecting error during the initial diagnosis of CAN controller of TCM | U1010 | U1010 | |
| BRAKE SWITCH B | When the brake switch does not switch to ON or OFF | P0703 | | |
| T/M RANGE SWITCH A | TCM does not receive the correct voltage signal (based on the gear position) from the switch. | P0705 | P0705 | |
| FLUID TEMP SENSOR A | During running, the CVT fluid temperature sensor signal voltage is excessively high or low | P0710 | P0710 | |
| INPUT SPEED SENSOR A | Primary speed sensor signal is not input due to an open circuit An unexpected signal is input when vehicle is being driven | P0715 | P0715 | |
| OUTPUT SPEED SENSOR | Signal from secondary speed sensor not input due to open or short circuit Unexpected signal input during running | P0720 | P0720 | |
| ENGINE SPEED | TCM does not receive the CAN communication signal from the ECM Engine speed is too low while driving | P0725 | | |
| INCORRECT GR RATIO | Unexpected gear ratio detected | P0730 | | |
| TORQUE CONVERTER | Normal voltage not applied to solenoid due to open or short circuit | P0740 | P0740 | |
| TORQUE CONVERTER | CVT cannot perform lock-up even if electrical circuit is good TCM detects as irregular by comparing difference value with slip rotation There is big difference engine speed and primary speed when TCM lock-up signal is on | P0744 | P0744 | |
| L/PRESS SOL/CIRC | Normal voltage not applied to solenoid due to open or short circuit TCM detects as irregular by comparing target value with monitor value | P0745 | P0745 | |
| PC SOLENOID A | Unexpected gear ratio was detected in the LOW side due to excessively low line pressure | P0746 | P0746 | |
| PC SOLENOID B | Secondary pressure is too high or too low compared with the commanded value while driving | P0776 | P0776 | |
| PC SOLENOID B | Normal voltage not applied to solenoid due to cut line, short, or the like TCM detects as irregular by comparing target value with monitor value | P0778 | P0778 | |
| UP/DOWN SHIFT SWITCH | When an impossible pattern of switch signals is detected, a malfunction is detected. | P0826 | | |
| FLUID PRESS SEN/SW A | Signal voltage of the secondary pressure sensor is too high or too low while driving | P0840 | P0840 | |
| FLUID PRESS SEN/SW A | Correlation between the values of the secondary pressure sensor and the primary pressure sensor is out of specification | P0841 | | |
| FLUID PRESS LOW | Secondary fluid pressure is too low compared with the commanded value while driving | P0868 | | |
| TCM | When the power supply to the TCM is cut OFF, for example because the battery is removed, and the self-diagnosis memory function stops This is not a malfunction message (Whenever shutting OFF a power supply to the TCM, this message appears on the screen) | P1701 | | |
| TP SENSOR | TCM does not receive the proper accelerator pedal position signals (input by CAN communication) from ECM | P1705 | | |
| VEHICLE SPEED (3) | CAN communication with the ABS actuator and the electric unit (control unit) is malfunctioning There is a great difference between the vehicle speed signal from the ABS actuator and the electric unit (control unit), and the vehicle speed sensor signal | P1722 | | |
| SPEED SENSOR | A rotation sensor error is detected because the gear does not change in accordance with the position of the stepping motor CAUTION: One of the "P0720", the "P0715" or the "P0725" is displayed with the DTC at the same time | P1723 | | |
| THROTTLE CONTROL SIG | The electronically controlled throttle for ECM is malfunctioning | P1726 | | |
| SLCT SOLENOID | Normal voltage not applied to solenoid due to cut line, short, or the like TCM detects as irregular by comparing target value with monitor value | P1740 | P1740 | |
| LINE PRESS CONTROL | TCM detects the unexpected line pressure | P1745 | | |
| STEP MOTOR | Each coil of the step motor is not energized properly due to an open or a short | P1777 | P1777 | |
| STEP MOTOR | There is a great difference between the number of steps for the stepping motor and for the actual gear ratio | P1778 | P1778 | |
| NO DTC IS DETECTED: FURTHER TESTING MAY BE REQUIRED | No NG item has been detected | X | X | |
| (1) These numbers are prescribed by SAE J2012. (2) Refer to " MALFUNCTION INDICATOR LAMP (MIL) ". (3) Models without ABS does not indicate. |
