Inspection Procedure

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 the intelligent tester. 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 (see FREEZE FRAME DATA ).

1. REPLACE ECM 
   1. Replace the ECM (see REMOVAL ).
2. CHECK WHETHER DTC OUTPUT RECURS

   2. Put the engine in inspection mode (see INSPECTION MODE PROCEDURE ).
   3. Connect the intelligent tester to the DLC3.
   4. Start the engine and wait for 10 minutes or more.
   5. Enter the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC / INFO / PENDING CODES.
