IMPORTANT: If you cannot duplicate the condition, operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records.

Observe the Balancing Rate parameters with a scan tool. Normal reading should be between +4 mm3 and -4 mm3 at idle, and between +6 mm3 and -6 mm3 in drive. With the engine running at idle, the Actual Fuel Rail Pressure should be close to the Desired Fuel Rail Pressure.
