P1815

P1815 M-MODE SWITCH





Description
- The manual mode switch, manual mode shift-up switch and manual mode shift-down switch are installed in the A/T shift selector assembly. It transmits manual mode switch, shift up and shift down switch signals to combination meter. Then combination meter transmits signals to TCM via CAN communication.
- Manual mode switch transmits manual mode switch signal or not manual mode switch signal to combination meter. Then TCM receives signals from combination meter via CAN communication.
- The manual mode shift-up switch transmits manual mode shift up signal to the combination meter. Then
TCM receives signal from the combination meter via CAN communication.
- The manual mode shift-down switch transmits manual mode shift down signal to the combination meter.
Then TCM receives signal from the combination meter via CAN communication.
- The paddle shifter transmits shift up and shift down switch signals to the combination meter. Then TCM receives signals from the combination meter via CAN communication.
- The TCM transmits manual mode indicator signal to the combination meter via CAN communication line.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If "DTC CONFIRMATION PROCEDURE" is previously conducted, always turn ignition switch OFF and wait at least 10 seconds before performing the next test.
- GO TO 2.
2.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select "SLCT LVR POSI" and "MANU MODE SW" in "Data Monitor" in "TRANSMISSION".
3. Maintain the following each conditions more than 60 seconds.

SLCT LVR POSI : D
MANU MODE SW : ON

4. Perform "Self Diagnostic Results" in "TRANSMISSION".
Is "P1815" detected?
YES - Go to "Diagnosis Procedure".
NO - INSPECTION END




Diagnosis Procedure
1.CHECK INPUT SIGNAL
With CONSULT-III
1. Turn ignition switch ON.
2. Select "MANU MODE SW", "NON M MODE SW", "UP SW LEVER", "DOWN SW LEVER", "SFT UP ST
SW" and "SFT DWN ST SW" in "Data Monitor" in "TRANSMISSION".
3. Check the ON/OFF operations of each monitor item.






Without CONSULT-III
Drive the vehicle in the manual mode, and then check that the indication of the shift position indicator matches with the actual gear position.
1. Shift the selector lever to UP side, and then accelerate from 1GR to 7GR.
2. Shift the selector lever to DOWN side, and then decelerate from 7GR to 1GR.
3. Shift the paddle shifter to UP side, and then accelerate from 1GR to 7GR.
4. Shift the paddle shifter to DOWN side, and then decelerate from 7GR to 1GR.
