OUTLINE
During the engine stall avoidance control operation, the function to display message on the multi information display has been added.
SYSTEM CONTROL
Engine Stall Avoidance Control
When an engine stall has occurred, the TCM suspects an ON malfunction of the linear solenoid valve SLU (lock-up control solenoid assembly), and engine stall avoidance control may be engaged by release of the C1 clutch or C3 clutch when the engine is started again. While engine stall avoidance control is engaged, creeping does not occur after the engine is restarted, even when in the D, S, or R shift position.
Tech Tips
During control operation, "Check Transmission System" is displayed on the multi-information display.
Slowly stepping on the accelerator pedal until the vehicle starts to move with the brake off engages the clutch, which makes departure possible.
When the linear solenoid valve SLU (lock-up control solenoid assembly) is normal, running at a constant speed for a short while with the engine speed from 1000 rpm to 3000 rpm releases engine stall avoidance control. The control can also be released by using Techstream and implementing the diagnosis code deletion procedure for the TCM. Furthermore, it is possible to carry out the deletion procedure even without the diagnosis code being entered.
When the vehicle departs, and then the linear solenoid valve SLU (lock-up control solenoid assembly) malfunctions or the vehicle stops before the above-mentioned conditions are reached, engine stall avoidance control is not released, so again creeping does not occur.
