CAUTION / NOTICE / HINT
When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing a new ECM, perform all of the initialization and registration procedures for the "Learning Values Write" function by following the instructions shown on the GTS display.
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
READ VALUE USING GTS (EXHAUST TEMPERATURE B1S2)
Connect the GTS to the DLC3.
Start the engine and warm it up.
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Data List / Exhaust Temperature B1S2.
Powertrain > Engine and ECT > Data ListTester Display |

If there is an open circuit, the GTS indicates 20°C (68°F).
If there is a short circuit, the GTS indicates 900°C (1652°F).

Turn the ignition switch to ON and wait for 10 seconds or more.
Start the engine and allow it to idle until the engine coolant temperature is 80°C (176°F) or higher.
Confirm that 11 minutes or more elapsed after engine was started.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
Confirm that the pending DTC is not output again.
