      Result

      Result Proceed to
      Only DTC P0335 is output or SFI system DTCs are not output. A
      DTC P0335 and other SFI system DTCs are output or any SFI system DTCs other than P0335 are output. B
    5. Turn the power switch off.

    B 

    GO TO DTC CHART (SFI SYSTEM) 

    (Refer to DIAGNOSTIC TROUBLE CODE CHART [10/2015 - 10/2016] , DIAGNOSTIC TROUBLE CODE CHART [10/2016 - 06/2017] , or DIAGNOSTIC TROUBLE CODE CHART [06/2017 - ] )

    REPLACE HYBRID VEHICLE TRANSAXLE ASSEMBLY 

    When Not Using the Engine Support Bridge: Refer to COMPONENTS [10/2014 - ]

    When Using the Engine Support Bridge: Refer to COMPONENTS [10/2015 - ]

    C 

    GO TO DTC CHART (HYBRID CONTROL SYSTEM) 

    (Refer to DIAGNOSTIC TROUBLE CODE CHART [10/2015 - ] )

    A 

    See step  3

  3. CHECK CRANKSHAFT PULLEY REVOLUTION (SHIFT LEVER IN P) 
    1. With the shift lever in P, lift up the vehicle.
    2. Turn the crankshaft pulley using hand tools to check if the crankshaft can rotate smoothly.
      WARNING:

      Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch off before performing this inspection, to prevent the engine from starting.

      NOTE:

      Engine compression causes resistance when turning the crankshaft pulley. Check if the crankshaft rotates smoothly (or if it is locked) by manually applying sufficient torque to turn the crankshaft pulley. The torque required to turn the crankshaft pulley should be the same as for a known good vehicle of the same type.

      Result

      Result Proceed to
      The crankshaft rotates. A
      The crankshaft does not rotate. B
    3. Lower the vehicle.

    See step  4

  4. CLEAR DTC 
    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
    4. Read and record the DTCs and freeze frame data.
    5. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
    6. Read and record the DTCs and freeze frame data.
    7. Clear DTCs and freeze frame data.
    8. Turn the power switch off.

    OK 

    See step  6

  6. CHECK CREEP MOVEMENT 
    1. Depress the brake pedal, move the shift lever to D, and release the brake pedal.

      OK

      The wheels turn (the vehicle creeps forward).

      HINT: 

      If the wheels do not turn and DTC P3147-239 is output, replace the hybrid vehicle transaxle assembly.

  8. CHECK CRANKSHAFT PULLEY REVOLUTION (N POSITION) 
    1. Turn the power switch on (IG) and move the shift lever to N.
    2. Lift up the vehicle.
    3. Turn the crankshaft pulley using hand tools to check if the crankshaft can rotate smoothly.
      WARNING:

      Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch on (IG) before performing this inspection, to prevent the engine from starting.
