9	PURPOSE: INSPECT CHARCOAL CANISTER SUB FOR MALFUNCTION Inspect the applicable part. (See CHARCOAL CANISTER INSPECTION (VIN M) .) (See CHARCOAL CANISTER INSPECTION (VIN 7, L) .) Is the part normal?	Yes	Go to the next step.
9		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See CHARCOAL CANISTER REMOVAL/INSTALLATION (VIN M) .) (See CHARCOAL CANISTER REMOVAL/INSTALLATION (VIN 7, L) .)
10	PURPOSE: INSPECT CATCH TANK FOR MALFUNCTION Inspect the applicable part. (See CATCH TANK INSPECTION (VIN M) .) (See CATCH TANK INSPECTION (VIN 7, L) .) Is the part normal?	Yes	Go to the next step.
10		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION (VIN M) .) (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION (VIN 7, L) .)
11	PURPOSE: INSPECT PURGE SOLENOID VALVE FOR MALFUNCTION Inspect the applicable part. (See PURGE SOLENOID VALVE INSPECTION (VIN M) .) (See PURGE SOLENOID VALVE INSPECTION (VIN 7, L) .) Is the part normal?	Yes	Go to the next step.
11		No	Repair or replace the malfunctioning location and perform the repair completion verification. (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION (VIN M) .) (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION (VIN 7, L) .)

Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Replicate the vehicle conditions at the time the DTC was detected using the following procedure. Implement the repeatability verification procedure. (See REPEATABILITY VERIFICATION PROCEDURE .) Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)] .) If the CAN communication is normal, perform the diagnosis from Step 1. If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION (VIN M) .) (See PCM REMOVAL/INSTALLATION (VIN 7, L) .)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
