| Description |
- i-stop function operates even though system is turned off by pressing i-stop OFF switch.
- i-stop function operates even though vehicle conditions are for non-operation.
- i-stop function operates frequently while parking vehicle.
|
| Possible cause |
i-stop warning light (amber) false illumination
- i-stop warning light (amber) illumination circuit in instrument cluster malfunction
- Malfunction in CAN communication line between instrument cluster and PCM
False detection of i-stop function operation conditions
- Falsely detects that i-stop OFF switch is switched off
- i-stop OFF switch malfunction
- Malfunction in wiring harness (including connector/terminal) between instrument cluster and cluster switch No. 1
- False detection of vehicle not being parked
- False detection of steering wheel rotation speed
- Steering angle sensor initialization malfunction
- EPS control module malfunction
- False detection of external vehicle temperature within operable range (-10 to 50°C {14 to 122°F})
- Ambient temperature sensor malfunction (sensor specific malfunction)
- Malfunction in wiring harness (including connector/terminal) between PCM and ambient temperature sensor
- Falsely detects that vehicle is under safety condition
- False detection of low power brake unit load
- Power brake unit vacuum sensor malfunction
- Malfunction in wiring harness (including connector/terminal) between electronically controlled brake unit/DSC HU/CM and power brake unit vacuum sensor
- False detection of closed hood
- Hood latch switch malfunction (stuck closed)
- Malfunction in wiring harness (including connector/terminal) between body control module (BCM) and hood latch switch (LH)
- False detection of closed door, liftgate
- Door latch switch malfunction
- Liftgate latch switch malfunction
- Malfunction in wiring harness (including connector/terminal) between door-electrical supply unit and front door latch and lock actuator
- Malfunction in wiring harness (including connector/terminal) between electrical supply unit (ESU) and rear door latch and lock actuator (LH)
- Malfunction in wiring harness (including connector/terminal) between body control module (BCM) and rear door latch and lock actuator (RH)
- Malfunction in wiring harness (including connector/terminal) between electrical supply unit (ESU) and liftgate latch and lock actuator
- False detection of fastened driver seat belt
- Driver-side buckle switch malfunction
- Malfunction in wiring harness (including connector/terminal) between dash-electrical supply unit and driver-side buckle switch
- False detection of inclination angle (7% or less)
- Low-G sensor (built-into SAS control module) malfunction (In this case, the SAS control module records DTCs C0061:29 and C0062:29).
- Low-G sensor (built-into SAS control module) initialization malfunction (In this case, the SAS control module records DTC U2100:00).
- Climate control unit falsely detects that internal vehicle temperature is within operation range.
- Passenger compartment temperature sensor malfunction (sensor specific or motor malfunction)
- Malfunction in wiring harness (including connector/terminal) between climate control unit and passenger compartment temperature sensor
- Falsely detects that climate control unit detects that driver-side air mix door is not in MAX COLD or MAX HOT position even though driver-side air mix door is in MAX COLD or MAX HOT position.
- Driver-side air mix actuator malfunction
- Driver-side air mix actuator position sensor malfunction
- Driver-side air mix door or linkage stuck
