K313 CVT  CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM  P061512  Starter Relay Circuit Short to Battery  


MONITOR DESCRIPTION

While the engine is being cranked, 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 begins running when the vehicle is driven at 20 km/h (12 mph) or more for 20 seconds.

CAUTION / NOTICE / HINT

CAUTION:
·
A371909

Strictly observe posted speed limits, traffic laws and road conditions.

·

Do not drive the vehicle with the cable of the GTS contacting the pedals, shift lever or steering wheel.

·

Driving the vehicle with the cable of the GTS contacting these areas could impede vehicle control, resulting in a serious accident.


·
A356953

Do not operate the GTS while driving the vehicle.

·

Operating the GTS while driving the vehicle will prevent you from paying sufficient attention to vehicle surroundings, and could result in a serious accident.



NOTICE:
·

Perform the universal trip to clear permanent DTCs.

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.
