Circuit description

After engine startup, if the engine stops due to any other cause than the ignition switch operation, the DTC is output. The conditions at the time the DTC was output can be checked from the freeze frame data using the SSM3. A part of the engine running conditions under which the engine trouble occurred is recorded in the freeze frame data, which is useful for troubleshooting.

It is necessary to check the fuel level before troubleshooting because engine stall due to running out of gas can also be detected.

DTC DETECTION CONDITION

DTC No.	DTC detection condition	Suspected parts
P1603	After completing the monitoring of a startup failure (P1604), the engine stops (the engine speed drops to 300 r/min or less) even if the ignition switch is not operated after the engine is started. (1 trips detection logic)	There is no air leakage in the intake system.
