Action for Non-repeatable Malfunction

•  If the malfunction does not recur, verify the malfunction cause by performing the following actions:
―  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. (See ELECTRICAL SYSTEM.)

i-stop control

•  The i-stop system is programmed to not function (stop or restart engine) while the bonnet is open, however, when performing servicing in the engine compartment be careful so as to prevent getting caught in a rotating part if the engine were too restart accidentally.
•  When performing an asterisks (*) troubleshooting inspection, shake the applicable part, wiring harness, and connector by hand to discover whether poor contact points are the cause of any intermittent malfunction. If there is a problem, inspect to make sure connectors, terminals and wiring harnesses are connected correctly and undamaged, and repair or replace if necessary.
•  Depending on the vehicle operation status and the conditions indicated in the table below, the engine may not stop or it may restart for a condition unrelated to driving operations (system is normal).

*1  :After the vehicle is stopped, the engine stops if the gear is shifted to N position. In addition, if the gear is shifted to P position after the vehicle is stopped in D position, the engine stop condition by the i-stop control is maintained.
*2  :If a door is opened while the vehicle is stopped, i-stop is inhibited until a vehicle speed record is input once.
*3  :If the engine is started with the hood open, i-stop is inhibited until the engine is stopped.
*4  :If the seat belt is unfastened while the vehicle is stopped, i-stop is inhibited until a vehicle speed record is input once.
*5  :When the A/C set temperature is set to MAX, the PCM may inhibit the i-stop control.
*6  :When all of the other i-stop permit conditions related to the climate control unit are met even if the airflow volume control dial is on, the i-stop control is permitted.
*7  :When shifting to the R position and driving the vehicle, the i-stop function is inhibited until the vehicle is driven at 5 km/h {3.0 mph} or more for 1 min or more, or the vehicle is driven at 15 km/h {9.3 mph} or more after shifting to the D or M position.
*8  :The engine stop condition continues even if the brake pedal is released while the autohold switch is on.
