Automatic Transaxle Fluid (ATF) Inspection

Using M-MDS 

• Connect the M-MDS to the DLC-2.
  Fig 2: Identifying DLC-2

  
• Verify the ATF temperature using the PID/DATA monitor function "TFT". (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION .).
  • High temperature (47 °C {117 °F}  or more)
  • Appropriate temperature (between 37 °C {99 °F}  and under 47 °C {117 °F}  )
  • Low temperature (less than 37 °C {99 °F}  )
• Start the engine.
• Warm up the engine while idling it until the ATF temperature reaches the lower limit of 37 °C {99 °F}  .
• Perform the following procedure.
  NOTE:

  • Perform the following procedure immediately because the ATF temperature will exceed the appropriate temperature (between 37 °C {99 °F}  and under 47 °C {117 °F}  ).
  • Shift the selector lever to each positions and hold for 2 s  or more.
    • Shift the selector lever in the order of P position→R position→N position→D position.
    • Shift the selector lever in the order of D position→N position→R position→P position.
    • Shift the selector lever in the order of P position→R position→N position→D position.
    • Shift the selector lever in the order of D position→N position→R position→P position.

  Using ATF temperature display mode 

• Engage the parking brake and use wheel chocks at the front and rear of the wheels.
  NOTE:

  • Perform the procedure for switching to the ATF temperature display mode within 3 min  . If the procedure is not completed within 3 min  , the switching procedure is cancelled.
  • If the flashing of each light cannot be verified as according to the procedure while switching to the ATF temperature display mode, the switching procedure has failed. Repeat the procedure from the beginning.
• Perform the following and verify that the gear position indicator light flashes 2 times.

  • Turn the A/C switch off.
  • Depress the brake pedal with the left foot and hold it in that condition (continue to depress the brake pedal until Step  5 is completed).
  • Shift the selector lever from the P position to the M position.
  • Depress the accelerator pedal with the right foot all the way down and hold it in that condition (continue to depress the brake pedal until Step  4 (3) is completed).
  • Shift the selector lever to the M (+) or M (-) and hold it in that condition.
  • Switch the ignition ON (engine off).
• Verify that the gear position indicator light flashes 2 times after approx. 5 s  .
• Perform the following procedure and verify that the N position display of the selector indicator light flashes 2 times.

  NOTE:

  • Slowly and firmly shift the selector lever operation.
    • Shift the selector lever in the order of M position→D position→N position→R position→P position.
    • Shift the selector lever in the order of P position→R position→N position.
    • Remove the right foot from the accelerator pedal.
    • Verify that the N position display flashes 2 times.
• Perform the following procedure and verify that the AT warning light flashes 2 times.

  • Start the engine.
  • Shift the selector lever quickly between the N position and the D position for 6 s  or more.
  • Verify that the AT warning light flashes 2 times.
• Perform the following procedure and verify that the P position display flashes.

  NOTE:

  • Shift the selector lever to each positions and hold for 2 s  or more.
    • Shift the selector lever to the P position.
    • Shift the selector lever in the order of D position→N position→R position→P position.
    • Shift the selector lever in the order of P position→R position→N position→D position.
    • Shift the selector lever in the order of P position→R position→N position→D position.
    • Shift the selector lever in the order of D position→N position→R position→P position.
    • Verify that the TCM switches to the ATF temperature display mode via the P position display flashing.
• Verify the ATF temperature using the P position display flashing pattern.
  NOTE:

  • Finish the "ATF temperature display mode" when any one of the following conditions is met:
    • Switch the ignition to ACC or off
    • Vehicle speed is 3 km/h {2 mph} or more 
    • Malfunction occurs in transaxle

ATF temperature		Selector indicator light (P position display) flashing pattern
High temperature (47 °C {117 °F}  or more)
Appropriate temperature (between 37 °C {99 °F}  and under 47 °C {117 °F}  )
Low temperature (less than 37 °C {99 °F}  )

• The ATF is muddy.
• The ATF smells strange or unusual.
