M20D-FKS ENGINE CONTROL  SFI SYSTEM  P061512  Starter Relay Circuit Short to Battery  


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 the DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.43 mph) or more for 20 seconds or more.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P061512 Starter Relay Circuit Short to Battery All of the following conditions are met, and 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 (12.43 mph) or more.

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

(c) The STA signal is on.

·

Perform driving pattern after confirming DTC enabling conditions



HINT:
·

If the judgment result is NORMAL, the system is normal.

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.
