Circuit/System Verification
1. Ignition ON, observe the DTC information with a scan tool. DTC P0651, P0652 or P0653 should not be set.
瀚慖f a DTC is set, refer to DTC P0641-P0643, P0651-P0653, or P0697-P0699 (ECM, LLT) ( See: P Code Charts/P0641).
2. Engine idling, observe the DTC information with a scan tool. DTC P0341, P0342, P0343, P0346, P0347, P0348, P0366, P0367, P0368,
P0391, P0392, or P0393 should not set.
3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
