AC60E AUTOMATIC TRANSMISSION / TRANSAXLE  AUTOMATIC TRANSMISSION SYSTEM(for 7GR-FKS)  P061512  Starter Relay Circuit Short to Battery  


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.

2.

Turn the ignition switch to ON and turn the GTS on.

3.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4.

Turn the ignition switch off and wait for at least 30 seconds.

5.

Turn the ignition switch to ON and turn the GTS on.

6.

Start the engine.

7.

Drive the vehicle for 20 seconds or more with the following conditions:

-

Engine speed is 1000 rpm or more.

-

Vehicle speed is 20 km/h (12.43 mph) or more.


8.

Stop the vehicle.

9.

Enter the following menus: Powertrain / Transmission / Utility / All Readiness.

10.

Input the DTC: P061512.

11.

Check the DTC judgment result.

GTS Display Description
