Inspection Procedure

HINT:

• DTC P2610 is set if an internal ECM (included in the hybrid vehicle control ECU) problem is detected. Diagnostic procedures are not required. ECM replacement is required.
• Read freeze frame data using the 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 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.
