DIAGNOSIS (JR405E) 7A2-131
No. F5: Engine Stalls Before Vehicle Stops from Running

Description:

The engine stalls simultaneously with the vehicle stop when the brake pedal is stepped on to stop the vehicle
during the running.

Possible Cause:

Trouble on the engine system side (fuel injection control, engine speed control, etc.) is considered.

Refer to "No. B5: Engine stalls when selecting from N range to R, D, 3, 2 or L range".





No. G1: Vehicle Moves in P Range or Parking Gear is Not
Disengaged other than P Range

Description:

Vehicle moves though it stops at a slope and P range is selected.

The engine stalls and vehicle does not move though other than P range is selected and the accelerator pedal is
stepped on.

Possible Cause:

Trouble of the parking mechanism (noise or shock may result).

Disordered selector cable (only when traveling in the P range).

If the vehicle moves in the N range, follow the procedure of "No. B1: Vehicle runs in N range".





No. G2: Creep Force is Large

Description:

Vehicle accelerates in D, 3, 2, L, and R ranges though the accelerator pedal is not stepped on.

Possible Cause:

Too high engine idling speed (not attributable to AT).

7A2-138 DIAGNOSIS (JR405E)
No. Z6: Poor Fuel Consumption

Description:

Poor fuel consumption.

Diagnosis Hints:

Basically same causes as "No. C1 - C8: Engine races up (slip) by shift up or shift down" are considered.



No. Z7: Pattern Select Switch is Faulty

Description:

Shift pattern does not change though the pattern select switch is turned on.

Possible Cause:

Faulty mode select switch is considered.



No. Z8: Oil is Splashed During the Running

Description:

Oil is splashed during the running

Possible Cause:

ATF quantity is too high.



No. Z9: Abnormal Smell

Description:

Abnormal smell.

Diagnosis Hints:

Basically a trouble in the AT main unit.



No. Z10: ATF Quantity is Low or High

Description:

Oil quantity is low or high.

Possible Cause:

In case of oil level is high.
ATF temperature is low when ATF quantity is checked.

In case of oil level is low.
ATF leaks is considered. Check the AT main unit and cooler circuit.
