Toyota Corolla Cross: Drive Start Control
DESCRIPTION
The drive start control is controlled by the ECM.
If the ECM determines that the shift lever and accelerator pedal are operated abnormally, engine output is restricted and, when necessary, a warning is displayed on the combination meter assembly.
CAUTION / NOTICE / HINT
HINT:
Even if the accelerator pedal position is maintained, the engine output may increase when driving uphill and decrease when driving downhill. This is due to the drive start control controlling the engine output, and is not a malfunction.
PROCEDURE
| 1. |
PAST ACTIVATION CONFIRMATION |
(a) Check if the customer operated the vehicle in a way that would cause the drive start control to operate.
- Pattern A (When all of the following conditions are met, control starts.)
- The accelerator pedal is open by approximately 1/5 or more.
- The shift lever is moved from P to any forward position D (other forward shift position) or R.
- Pattern B (When all of the following conditions are met, control starts.)
- The accelerator pedal is open by approximately 1/5 or more.
- The shift lever is moved from R to any forward position D (other forward shift position), any forward position D (other forward shift position) to R, or N to R.
HINT:
Operation may not be possible in certain situations.
- Items Controlled
- Engine output is restricted.
- Deactivation Conditions
- The accelerator pedal is released.
- The shift lever is in P or N.
HINT:
- The restraint level for engine output differs for pattern A and pattern B.
- Engine output is corrected according to the slope incline when control is in operation.
- Control will not operate when TRC operation is stopped.
- Control will also not operate under the following conditions. (equipped models only)
- When in auto LSD mode
- When the transfer switch is operated to switch the status to L4
- When the center differential is locked
- When multi-terrain select is selected
