7A2-130 DIAGNOSIS (JR405E)
No. F2: Engine Races Up During Acceleration (Slip)
Description:
The engine speed up when the accelerator pedal is stepped on for acceleration and the gear is shifted up or
down.
Only the engine speeds up but vehicle speed does not increase when the accelerator pedal is stepped on for
acceleration during the running.
Diagnosis Hints:
Basically same causes as "No. C1 - C8: Engine races up (slip) by shift up or shift down" are considered.
When the condition of No. C1-C8 grows worse, symptom of No. F2 results.
No. F3: Noise or Vibration During the Running in R, D, 3, 2 or L Range
Description:
Noise or vibration is generated in the vicinity of AT during the running.
Diagnosis Hints:
Cause other than AT can be also considered. It is effective means to reproduce a running condition using a lift
up, chassis dynamo, etc. to investigate the origin (generating condition) of noise and vibration.
Caution:
Lifting up some unit to test it accompanies danger. Provide safety measures as far as possible and
carry out the test with sufficient care.
Possible Cause:
Following sources of noise or vibration other than the AT can be considered.
Noise from differential gears.
Noise from propeller shaft.
The bearing support in the middle of the propeller shaft has fatigued, and the bend angle of the propeller shaft
has changed, causing vibration at the time of start.
Unbalanced and poor uniformity of tires cause vibration.
No. F4: Engine Brake Does Not Apply in L Range
Description:
The engine brake does not apply, allowing the vehicle to run freely when the accelerator pedal is released at low
speed in L range.
Possible Cause:
Slip of clutch (low & reverse brake)
If slip of clutch is caused, a DTC (gear ratio error) is stored.
Faulty input/output signal system.
Low & reverse brake duty solenoid
Faulty control valve (faulty operation, sticking).

7A2-146 DIAGNOSIS (JR405E)
5. If there is no reverse.
Reverse clutch malfunction.
Reverse clutch hydraulic circuit failed.
Low & reverse brake hydraulic circuit failed.
Low & reverse brake duty solenoid stick.
Refer to symptom diagnosis "No. A2: Vehicle Dose Not
Run in R Range" or DTC section "Low & Reverse
Brake Duty Solenoid Failure".
6. If there is no parking.
Parking pawl malfunction.
Refer to symptom diagnosis "No. G1: Vehicle Moves in
P Range or Parking Gear in Not Disengaged othe
r
than P Range".
NOTE:
The check for the cause of abnormal noise and vibration
must be made with extreme care as it could also be due to
loss of balance in propeller shaft, differential, the torque
converter, etc. Or insufficient bending, rigidity, etc. in the
powertran.
