Troubleshooting Procedure

am3zzw00012949

Action for Non-repeatable Malfunction

―  Based on the repair order form, attempt to drive the vehicle or perform tests to replicate the malfunction, record the data (such as PCM circuit voltage) at that time, and detect the malfunction cause.

―  Shake the wiring harness or connector of the electrical component which is suspected to be the cause of the malfunction, and inspect for malfunction or occurrence of any DTCs.

―  Inspect the female terminals on the connector of the electric component which is suspected to be the cause of the malfunction for poor connection.

i-stop control

i-stop (engine-stop control) permit condition

•  The conditions to stop the engine by the i-stop control are as follows:

Purpose	Condition item
Driveability	Vehicle speed	0 km/h {0 mph}
	Brake pedal	Brake pedal depressed in D position or M position (except 2nd gear fixed mode) (If ABS operates during deceleration, i-stop operation is inhibited.)
	Brake fluid pressure	Brake fluid pressure is 1.25 MPa {12.7 kgf/cm2, 181 psi} or more in D position or M position (except 2nd gear fixed mode) (pedal force sufficient to suppress vehicle lurch when engine is restarted)
	Accelerator pedal	Released (foot removed from accelerator pedal)
	Vehicle conditions	Vehicle stopped in D position (After vehicle is stopped and shifted into N position, engine stops 0.6 s after operation. In addition, after vehicle is stopped in D position and if shifted into P position, engine stop condition continues by i-stop control
Marketability	Cabin temperature	Difference between target temperature in cabin and temperature in cabin is within a certain value (A/C cabin temperature control is performed)
	A/C temperature	Setting other than MAX/MIN
	Ambient temperature	-10―50 °C {14―122 °F}
	Steering speed	10 deg/sec or less (After EHPAS control module learned center value)
	Steering angle	-65―65 ° (Center) (After EHPAS control module learned center value)
	EHPAS control module consumption current	16 A or less
	i-stop OFF switch	OFF
	Vehicle speed history	3 km/h {2 mph} or more
	Advanced key	Authorization is possible/No authorization failure on previous engine stop by i-stop control (The i-stop operation is also inhibited if the battery for the advanced key is depleted.)
Safety	Battery charge condition	68.4% or more (determined from current sensor signal))
	Battery fluid temperature	0—70 °C {32—158 °F}
	Battery voltage	11.2 V or more
	Estimated battery voltage during engine restart	7.45 or more*1
	Defroster switch	OFF
	Power brake unit vacuum	-43 kPa {-0.44 kgf/cm2, -6.2 psi} or less am3zzw00012952
	Door (front, rear)	Closed
	Bonnet	Closed*2
	Liftgate	Closed
	Vehicle inclination angle	When level, less than ± 12 %
	Seat belt (driver)	Fastened
	System condition	i-stop related module normal
System restriction	Number of starter operations	Within 180,000 times
	Number of starter relay operations	Within 180,000 times
	Time period from engine stop by i-stop control from vehicle stop	0.25 s or more
	ISC learning	Completed
	Battery conditioning learning	Completed
	Steering angle sensor initialization setting	Completed
	DSC sensor initialization	Completed
	Elapsed time after engine restart	Maximum 6.4 s or more (Engine stop time fluctuates according to i-stop control)
	PCM DTC	DTC except P2299:00 (Brake override system) not detected
Engine condition	Engine coolant temperature	55—110 °C {131—230 °F}
	Intake air temperature	100°C {212 °F} or less
	ATF temperature	20―120 °C {68―248 °F}
Environment condition	Altitude	1,500 m or less

i-stop (engine restart control) conditions

•  Conditions for restarting the engine during i-stop control (engine stopped) are as follows:

Driver operation	Brake pedal released → depressed while in P or N position
	Brake pedal depressed → released while in D or M position (except 2nd gear fixed mode)
	Accelerator pedal depressed while in D or M position (except 2nd gear fixed mode)
	Steering angle (D or M position (except 2nd gear fixed mode)): 70 deg/sec or more (after EHPAS control module learned center value)
	Steering angle (D or M position (except 2nd gear fixed mode)): -70° or less or 70° or more (after EHPAS control module learned center value)
	Engine start by key operation
	Shift operation	P or N position →D or L or R position
Marketability	A/C request
	A/C temperature MAX setting, MIN setting
	Battery charge 67.9% or less
	Battery charge rate is specified value or more
	Battery voltage is 11 V or less
	Estimated battery voltage when engine is restarted is 7.25 V or less
	i-stop OFF switch on
	•  The following conditions are met while in P or N position (determined that driver is not in vehicle). ―  Seat belt (driver): Not fastened ―  Door (driver): Open
	•  The following conditions are met, advanced key removed: ―  Seat belt (driver): Fastened ―  Door (driver): Closed ―  Door (Any door except driver): Open
Safety	Defroster switch on
	•  Any of the following conditions met ―  Brake fluid pressure is 0.35 MPa {3.6 kgf/cm2, 51 psi} or less while in D or M position (except 2nd gear fixed mode) ―  Brake fluid pressure is 13 MPa {133 kgf/cm2, 1885 psi} or less while in R position
