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 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 occurrence of any malfunction or 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 control is designed to not function (idling stop or engine restart) while the bonnet is open, however, when performing servicing in the engine compartment while a malfunction symptom has being occurred, be careful not to get caught in a rotating part if the engine were too restart accidentally.
•  When performing troubleshooting indicated with an asterisked (*), shake the applicable part, wiring harness, and connector by hand to determine if the malfunction is temporal caused by poor contact. If there is a malfunction in the connectors or terminals, properly connect them and repair or replace if necessary. If there is a malfunction in the connectors or terminals, properly connect them and repair or replace if necessary.
•  Engine-stop permit conditions and engine restart conditions by i-stop control as follows:

*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 the engine is started with the hood open, i-stop is inhibited until the engine is stopped.
*3  :If the seat belt is unfastened while the vehicle is stopped, i-stop is inhibited until a vehicle speed record is input once.
*4  :The i-stop operation is inhibited until the ethanol concentration learning for the fuel is completed after refueling.
