CAUTION / NOTICE / HINT

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.

PROCEDURE

Powertrain > Engine and ECT > Trouble Codes

If P0630 is output, the VIN must be input to the ECM using the Techstream. However, all DTCs are cleared automatically by the Techstream when the VIN is input. If DTCs other than P0630 are output, troubleshoot them first.
