7A2-106 DIAGNOSIS (JR405E)
No. B6: Engine Starter Does Not Run in P or N Range
No. B7: Engine Starter Runs Except in P or N Range
Description:
The engine starter does not run though the P or N range is selected.
The engine starter runs though the R or D, 3, 2or L range is selected.
Possible Cause:
Disordered select cable.
Disordered Inhibitor switch, disconnection or short-circuit of inhibitor switch.
No. B8: Extended Time Lag When Shift Lever is Changed to N to D
Description:
The shift time lag is longer than standard value when shift lever is changed to N to D.
Possible Cause:
Forward range line pressure is low.
Slip of low & reverse clutch.
Slip of low one-way clutch.
Trouble in control valve body (faulty operation, sticking, clogged oil passage).
Faulty low clutch duty solenoid operation.
Shortage or faulty quality of ATF.
No. B9: Extended Time Lag When Shift Lever is Changed to N to R
Description:
The shift time lag is longer than standard value when shift lever is changed to N to R.
Possible Cause:
Reverse range line pressure is low.
Slip of low & reverse brake.
Slip of reverse clutch.
Trouble in control valve body (faulty operation, sticking, clogged oil passage).
Faulty low & reverse brake duty solenoid operation.
Shortage or faulty quality of ATF.

DIAGNOSIS (JR405E) 7A2-107
No. B10: Brake is Applied in R Range
Description:
Brake is applied suddenly in R range.
Diagnosis Hints:
Basically a trouble in the AT main unit. However, some trouble in the sensor system or output system may have
some influence on the trouble in the main unit and therefore these systems should be also checked to prevent
reproduce of the trouble.
Possible Cause:
Seized clutch (low clutch, high clutch, 2-4 brake).
Shortage or faulty quality of ATF.
Trouble in control valve body (faulty operation, sticking, clogged oil passage).
Disordered select cable (select indicator light indicates R but the hydraulic system is not in the R range).
Malfunction of parking mechanism.
No. B11: Insufficient Starting or Shaking in D Range
Description:
Insufficient starting or shaking in D range.
Possible Cause:
Slip of clutch (low clutch, low one-way clutch, reverse clutch, low & reverse brake).
If slip of clutch is caused, a DTC (gear ratio error) is stored.
Shortage or faulty quality of ATF.
Dropped line pressure.
Trouble in control valve body (faulty operation, sticking, clogged oil passage).
No. B12: Noise or Vibration is Generated at Starting
Description:
Noise or vibration is generated in the vicinity of AT at starting.
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.

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).
