Note. Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ). Do not turn the ignition switch to LOCK (0) or ACCESSORY (I) while updating the PCM. If you turn the ignition switch to LOCK (0) or ACCESSORY (I) before completion, the PCM can be damaged.

  1. Do the PCM update procedure (A/T system) (see «PCM UPDATE»(ref-360284-S30758408212010042800000) ).
  2. Check for Pending or Confirmed DTCs with the HDS. Is DTC U0302 indicated? YES -Replace the original PCM (see «PCM REPLACEMENT»(ref-360284-S39322714792010042800000) ). NO -Troubleshooting is complete.

  1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice).
  2. Apply the parking brake, and block both rear wheels.
  3. Start the engine, then shift the shift lever to D, while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The engine should not stall.
  4. Repeat step 3 in all shift lever positions.
  5. Turn the ignition switch to LOCK (0).
  6. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
  7. Turn the ignition switch to ON (II).
  8. Make sure the HDS communicates with the PCM, and go to the A/T Data List. If it does not, go to the DLC circuit troubleshooting (see «DLC CIRCUIT TROUBLESHOOTING»(ref-360284-S14481644492010042800000) ).
  9. Prepare the HDS to take a HIGH SPEED SNAPSHOT (refer to the HDS user's guide for more details if needed): Select High Speed icon. Select these parameters: Vehicle Speed Output Shaft (Driven Pulley) Speed (rpm) Input Shaft (Drive Pulley) Speed (rpm) Engine Speed APP Sensor A (V) Battery Voltage Brake Switch Set the Trigger Type to Parameter. Adjust the Parameter setting to APP Sensor A above 1.1 V. Set the recording time to 60 seconds. Set the Trigger point to -30 seconds.
  10. Find a suitable level road. When you are ready to do the test, press OK on the HDS.
  11. Monitor the HDS, and accelerate quickly until APP Sensor A reads 1.2 V. Maintain a steady throttle at 1.2 V until the vehicle reaches a reasonable speed, then slow the vehicle, and come to a stop.
  12. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary and repeat step 11 .
  13. Adjust the Parameter setting to 2.2 V. Test-drive the vehicle again. While monitoring the HDS, accelerate quickly until APP Sensor A reads 2.3 V. Maintain a steady throttle at 2.3 V until the vehicle reaches a reasonable speed, then slow the vehicle, and come to a stop.
  14. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary and repeat step 13 .
  15. Accelerate quickly until the accelerator pedal is to the floor. Maintain a steady pedal until the vehicle reaches to reasonable speed, then slow to a stop, and save the snapshot. Repeat steps 11 thru 14 in D, S, and L positions.
  16. Review each snapshot individually, and compare APP Sensor A Voltage, Vehicle Speed, and Engine Speed to the following table: D Position: TERMINAL VOLTAGE REFERENCE APP Sensor A voltage Vehicle Speed Engine Speed 1.2 V 25 mph (40 km/h) 900-1,300 rpm 2.3 V 25 mph (40 km/h) 1,975-2,575 rpm 37 mph (60 km/h) 2,150-2,750 rpm 62 mph (100 km/h) 2,500-3,100 rpm 4.5 V 25 mph (40 km/h) 2,750-3,900 rpm 37 mph (60 km/h) 4,350-5,500 rpm 62 mph (100 km/h) 5,450-6,050 rpm S Position: TERMINAL VOLTAGE REFERENCE APP Sensor A voltage Vehicle Speed Engine Speed 1.2 V 25 mph (40 km/h) 1,600-2,000 rpm 37 mph (60 km/h) 1,825-2,425 rpm 62 mph (100 km/h) 2,450-3,050 rpm 2.3 V 25 mph (40 km/h) 2,250-2,850 rpm 37 mph (60 km/h) 2,550-3,150 rpm 62 mph (100 km/h) 3,150-3,750 rpm 4.5 V 25 mph (40 km/h) 4,150-5,050 rpm 37 mph (60 km/h) 5,250-6,200 rpm 62 mph (100 km/h) 5,450-6,050 rpm L Position: TERMINAL VOLTAGE REFERENCE APP Sensor A voltage Vehicle Speed Engine Speed 1.2 V 25 mph (40 km/h) 3,050-3,650 rpm 37 mph (60 km/h) 3,600-4,200 rpm 62 mph (100 km/h) 4,150-4,750 rpm 2.3 V 25 mph (40 km/h) 3,900-4,500 rpm 37 mph (60 km/h) 4,375-4,975 rpm 62 mph (100 km/h) 4,800-5,400 rpm 4.5 V 25 mph (40 km/h) 3,600-4,600 rpm 37 mph (60 km/h) 4,300-5,300 rpm 62 mph (100 km/h) 5,500-6,100 rpm
  17. Park the vehicle on a slope (about 16-degrees), apply the brake, and shift into P. Release the brake; the vehicle should not move. NOTE: Always use the brake to hold the vehicle when stopped on an incline in gear. Depending on the grade of the incline, the vehicle could roll backwards if the brake is released.

Scheme 354: Stall Speed Test
  1. Make sure the transmission fluid is filled to the proper level (see «CVT FLUID LEVEL CHECK»(ref-360271-S08457300192010042800000) ).
  2. Apply the parking brake, and block all four wheels.
  3. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
  4. Turn the ignition switch to ON (II).
  5. Make sure the HDS communicates with the PCM, and go to the A/T Data List. If it does not, go to the DLC circuit troubleshooting (see «DLC CIRCUIT TROUBLESHOOTING»(ref-360284-S14481644492010042800000) ).
  6. Check the IMA battery charge level. If the IMA battery level indicator displays no level, hold the engine speed between 3,500 and 4,000 rpm without load (in P or N) until the level in the indicator is half full.
  7. Make sure the A/C switch is OFF.
  8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice).
  9. Shift the shift lever to D, while pressing the brake pedal firmly, then press the accelerator pedal for 6 to 8 seconds, and note the engine speed. Do not move the shift lever while raising the engine speed.
  10. Allow 2 minutes for cooling, then repeat the test with the shift lever in S, L, and R. NOTE: Do not test stall speed for more than 10 seconds at a time. Stall speed tests should be used for diagnostic purposes only. Do not test stall speed with the A/T pressure gauges installed.
