DTC Related Item (Engine Control System)
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. | |
| Device fix mode |
|

FAIL SAFE PATTERN
| Pattern | Fail safe mode | |
|---|---|---|
| A | Traveling control mode | Accelerator angle variation control |
| B | Engine output control | |
| C | Device fix mode | |
| D | Supercharging stop mode | Supercharger bypass valve control is stopped and becomes the fully open condition. |

Throttle position sensor | - | - | - | * | The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10 degrees. The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. So, the acceleration will be poor. |
