Turbo high pressure models
Description
When a DTC is detected, ECM executes a mode (in the Fail-safe mode) applicable to the DTC. The fail-safe mode has the preset traveling control mode (accelerator angle variation and engine output limit) and device fix mode.
|
Fail safe mode |
Vehicle behavior |
|
|
Traveling control mode |
Accelerator angle variation control |
ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.
NOTE:
ECM does not control the accelerator pedal releasing speed.
|
|
Engine output control |
ECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle speed to encourage the driver to repair malfunction.
NOTE:
This value is a reference value converted from engine power to vehicle speed.
Actual power limitation value differs due to the malfunctioning part and driving condition. |
|
|
Device fix mode |
|
|
|
Combustion control mode |
Stratified charge combustion control at starting |
No stratified charge combustion at starting (cold start). |
|
Idle speed control |
Stops feedback control of idle speed and controls with specified speed. |
|
|
Recovery speed control at decelerating |
Stops recovery speed control by the fuel cut at decelerating and controls with specified speed. |
|
|
Ignition timing correction control |
Partially controls ignition timing control. |
|
|
Retardation control |
Controls ignition timing delay control in the intermediate water temperature range. |
