• Use the chart below to verify the symptoms of the trouble in order to diagnose the appropriate area.
-
Note
-
• When driving on high-altitude roads, the TCM determines that the driving mode is the AAS mode, and may change to a different shift timing from the normal timing.

|---|---|---|
|
Vehicle does not move in D, M or R position
|
• Vehicle does not move when accelerator pedal is depressed.
• The engine revs up but the vehicle does not move even though the accelerator pedal is depressed.
• Tires are locked and do not move even though the accelerator pedal is depressed.
|
|
|
Vehicle moves in P position, or parking gear does not disengage when P is disengaged
|
• Vehicle rolls when on a downward slope in P position.
• Vehicle does not move in D, M and R position when accelerator pedal is depressed, and engine remains in stalled condition.
|
|
|
Excessive creep
|
• Vehicle accelerates in D and R position when accelerator pedal is not depressed.
|
|
|
No creep at all
|
• Vehicle does not move in D , M or R position when idling on flat paved road.
|
|
|
Low maximum speed and poor acceleration
|
• Vehicle acceleration is poor at start.
• Delayed acceleration when accelerator pedal is depressed while driving.
|
|
|
No shifting
|
• Single shift position only.
• Sometimes shifts correctly.
|
|
|
Does not shift to 5GR or 6GR
|
• Vehicle does not upshift from 4GR to 5GR or 5GR to 6GR even though vehicle speed is increased.
• At a vehicle speed range where the transaxle should shift up to 5GR and 6GR gears in D position based on the shift pattern, the transaxle does not shift to 5GR and 6GR gears by gradually releasing the accelerator pedal.
|
|
|
Abnormal shifting
|
• Shifts incorrectly (incorrect shift pattern).
|
|
|
Frequent shifting
|
• Downshifting occurs suddenly even when accelerator pedal is depressed slightly in D position.
|
|
|
Shift point is high or low
|
• Shift point considerably different from automatic shift diagram.
• Shift delays when accelerating.
• Shift occurs suddenly when accelerating and engine speed does not increase.
|
|
|
No kickdown
|
• Does not downshift when accelerator pedal is fully depressed within kickdown range.
|
|
|
Engine flares up or slips when upshifting or downshifting
|
• When shifting up while accelerating the vehicle with the accelerator pedal depressed, the engine revs.
• When shifting down while the vehicle is being driven normally with the accelerator pedal depressed, the engine revs rapidly.
|
|
|
Judder upon torque converter clutch (TCC) operation
|
• Vehicle jolts when TCC is engaged.
|
|
|
Excessive shift shock from N to D or N to R position
|
• Strong shock is felt when shifting from N to D or N to R position at idle.
|
|
|
Slow engaging after operating selector lever from N to D position
|
• Slow engagement when depressing the accelerator pedal just after operating the selector lever from N to D position with the ATF temperature at 60 °C {140 °F} or more.
• Malfunction symptom only occurs once when accelerating from a standstill.
• Engagement after operating the selector lever from N to R position is normal.
• Engagement when shifting gears while driving is normal.
• DTCs are not stored.
|
|
|
Excessive shift shock is felt when upshifting and downshifting
|
• Excessive shift shock is felt when depressing accelerator pedal to accelerate at upshifting.
• During cruising, excessive shift shock is felt when depressing accelerator pedal at downshifting.
|
|
|
Excessive shift shock on torque converter clutch (TCC)
|
• Strong shock is felt when TCC is engaged.
|
|
|
Noise occurs at idle when vehicle is stopped in all positions
|
• Transaxle is noisy in all positions when vehicle idling.
|
|
|
Noise occurs at idle when vehicle is stopped in D, M or R position
|
• Abnormal noise/vibration occurs in the area around the ATX while the vehicle is being driven.
|
|
|
Transaxle overheats
|
• Burnt smell emitted from the transaxle.
• Smoke is emitted from the transaxle.
|
|
|
Engine stalls when shifted to D, M or R position
|
• Engine stalls when shifting from N or P position to D, M or R position at idle.
|
|
|
Starter does not work
|
• Starter does not work even when in P or N position.
|
|
|
Gear position indication does not illuminate in M position
|
• Gear position indication in instrument cluster does not illuminate in M position with the ignition switched ON (engine off or on).
|
|
|
Gear position indication illuminates in P, R, N and D positions
|
• Gear position indication in instrument cluster illuminates in P, R, N and D positions with the ignition switched ON (engine off or on).
|
|
|
Manual shift mode indication does not illuminate in M position/Manual shift mode indication illuminates in D position
|
• The Manual shift mode indication does not illuminate in M position.
• The shift position indication displays M in a position (P, R, N, or D position) other than M.
|
|
|
ATF seeping from automatic transaxle
|
• ATF is seeping from the automatic transaxle case.
• Foreign matter mixed with ATF is in the automatic transaxle case.
