Inspection Procedure

WARNING: This page is about a different car, the 2008 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

DTC P2610 is set if an internal ECM problem is detected. Diagnostic procedures are not required. ECM replacement is required.
Read freeze frame data using Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction (See FREEZE FRAME DATA ).

REPLACE ECM
CHECK WHETHER DTC OUTPUT RECURS
1. Connect Techstream to the DLC3.
2. Turn the engine switch on.
3. Clear DTCs (See DTC CHECK / CLEAR ).
4. Start the engine and wait for 10 minutes or more.
5. On the tester, enter the following menu items: Powertrain / Engine and ECT / Trouble Codes / Pending.
6. If no pending DTC is displayed, the repair has been successfully completed.
