Troubleshooting guide

Most of the automatic transaxle control system is electrically controlled. This often makes it difficult to diagnose
intermittent problems in system. Before undertaking actual checks, take a few minutes to talk with customers who
approach you with a driveability complaint. the customer is often a good source of information regarding intermittent
problems. Through talks with customer, one can find out what the symptoms are and under conditions they occur.

Troubleshooting item

Description

#

Trouble

1

Will start in other than P and N range

Engine starts in P, N, and other ranges

2

Engine stalls

Idle when shifted from
N or P to other ranges

Engine stops unexpectedly when shifted from N or P to
other ranges at idle

3

On deceleration

Engine stops unexpectedly at beginning of deceleration or
recovery from deceleration exhaust afterburn

4

Engine rough

On deceleration

Engine shakes at beginning of deceleration, during
deceleration, or recovery from deceleration

5

Poor acceleration

At drive-away

Engine speed increases normally but vehicle speed slowly
increases during drive-away

6

On acceleration

Engine speed increases normally but vehicle speed slowly
increases during acceleration

7

Surges while cruising

Momentary minor irregularity in engine output at steady
vehicle speed

8

Lack of power

Performance poor under load (i. e., power down when
climbing hills)

9

Poor fuel economy

Fuel economy unsatisfactory

10

Vehicle does not move in D, 2, 1 and/or R
range

No creep at all
Vehicle does not move when accelerator pedal depressed
after shifted to D, 2, 1 and/or R range

11

Vehicle moves in N range

Vehicle creeps in N range
Vehicle moves when accelrator pedal not depressed

12

Vehicle moves in P range

Vehicle rolls in P range

13

Excessive creep

Vehicle moves quickly in D, 2, 1 and R range (accelerator
pedal not depressed)

Excessive N to R range and N to D range shift shock
felt

14

No shift

Single range shift (1GR→2GR, 2GR→3GR, or 3GR→O/D)
only Sometimes shifts correctly

Gear position held in O/D OFF mode

15

Abnormal shift

Shifts incorrectly (incorrect shift pattern)
Example : vehicle shifts 1GR→O/D directly when
accelerating with accelerator pedal depressed slightly

16

Frequent shifting

Downshift occurs when accelerator depressed slightly in D,
S or 2 and L or 1 ranges (except hold mode)

17

Shift point high or low

Shift points do not match shift diagram
Shift delayed when accelerating
Shifts occur too fast when accelerating and engine speed
does not increases

18

No lock-up

No lock-up when vehicle speed reaches lock-up range
