SYMPTOM TROUBLESHOOTING ITEM TABLE [FW6A-EL]


id050315100300

•  Use the chart below to verify the symptoms of the trouble in order to diagnose the appropriate area.
Note
•  If a tire of a different diameter from the standard tire is installed, the TCM determines that the driving mode is the AAS mode, and may change to a different shift timing from the normal timing.

Description

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.
•  Vehicle does not shift to 5GR or 6GR even though accelerator pedal is released in D position at 45 km/h {28 mph} (5GR) or 55 km/h {34 mph} (6GR).
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.
Torque converter clutch (TCC) non-operation
•  TCC does not operate when vehicle reaches TCC operation range.
No kickdown
•  Does not downshift when accelerator pedal is fully depressed within kickdown range.
Engine flares up or slips when upshifting or downshifting
•  When accelerator pedal is depressed, engine speed increases normally but vehicle speed increases slowly.
•  When accelerator pedal is depressed while driving, engine speed increases but vehicle speed does not.
Engine flares up or slips when accelerating vehicle
•  Engine flares up when accelerator pedal is depressed for upshifting.
•  Engine flares up suddenly when accelerator pedal is depressed for downshifting.
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
•  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, it takes 3 s or more to engage.
•  Malfunction symptom only occurs once when accelerating from a standstill.
•  Engagement after operating the selector lever from N to R position is normal.
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
•  Transaxle is noisy in driving positions when vehicle is idling.
No engine braking in 1GR position of M position
•  Engine speed drops to idle but vehicle coasts when accelerator pedal is released when in M position (1GR) at low vehicle speed.
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.
Engine stalls when driving at slow speeds or stopping
•  Engine stalls when brake pedal is depressed while driving at low speed or stopping.
Starter does not work
•  Starter does not work even when in P or N position.
Gear position indicator light does not illuminate in M position
•  Gear position indicator light in instrument cluster does not illuminate in M position with the ignition is ON.
Gear position indicator light illuminates in P, R, N and D positions
•  Gear position indicator light in instrument cluster illuminates in P, R, N and D positions with the ignition is ON.
M position indicator light does not illuminate in M position/M position indicator light illuminates in D position
•  M position indicator light in instrument cluster does not illuminate in M position or M position indicator light in instrument cluster in P, R, N and D positions with the ignition is ON.
ATF seeping from automatic transaxle
•  ATF is seeping from the automatic transaxle case.
•  Foreign matter mixed with ATF is in the automatic transaxle case.
