2NZ-FE ENGINE CONTROL  SFI SYSTEM  P0617  Starter Relay Circuit High  


MONITOR DESCRIPTION

While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM. If the ECM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores this DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) or more for over 20 seconds or more.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P0617 Starter Relay Circuit High When all of the following conditions are met, and a (+B) battery voltage of 10.5 V or higher is applied to the ECM for 20 seconds (1 trip detection logic):

(a) The vehicle speed is 20 km/h (12.4 mph) or more.

(b) The engine speed is 1000 rpm or higher.

(c) The STA signal is ON.

NORMAL
·

DTC judgment completed

·

System normal


ABNORMAL
·

DTC judgment completed

·

System abnormal


INCOMPLETE

CAUTION / NOTICE / HINT

HINT:

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
