Repeatability Verification Procedure

PID Item/Simulation Item Used In Diagnosis

Function Inspection Using M-MDS

Step	Inspection	Results	Action
1	PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY •  Verify related Service Bulletins, on-line repair information, or Service Information availability. •  Is any related Information available?	Yes	Perform repair or diagnosis according to the available information. •  If the vehicle is not repaired, go to the next step.
		No	Go to the next step.
2	PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION •  Record the freeze frame data/snapshot data. Note •  Recording can be facilitated using the screen capture function of the PC.	—	Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

―  Perform an inspection of the connectors and wiring harnesses between the revolution sensor and the PCM.

―  Verify the revolution sensor installation condition.

―  Perform a unit inspection of the revolution sensor.

―  Inspect the manual transaxle for a malfunction depending on repeatability.

―  Verify that the primary malfunction is resolved and there are no other malfunctions.

Step	Inspection	Results	Action
1	PURPOSE: INSPECT REVOLUTION SENSOR CONNECTOR FOR MALFUNCTION •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
2	PURPOSE: INSPECT REVOLUTION SENSOR POWER SUPPLY CIRCUITS, SIGNAL CIRCUITS, AND GROUND CIRCUITS FOR SHORT TO GROUND •  Inspect the applicable circuit for a short to ground. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
3	PURPOSE: INSPECT PCM CONNECTOR FOR MALFUNCTION •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
4	PURPOSE: INSPECT REVOLUTION SENSOR POWER SUPPLY CIRCUITS, SIGNAL CIRCUITS, AND GROUND CIRCUITS FOR SHORT TO POWER SUPPLY •  Inspect the applicable circuit for a short to power supply. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
5	PURPOSE: INSPECT REVOLUTION SENSOR POWER SUPPLY CIRCUITS, SIGNAL CIRCUITS, AND GROUND CIRCUITS FOR SHORT CIRCUIT •  Inspect the applicable circuits for a short circuit. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
6	PURPOSE: INSPECT REVOLUTION SENSOR POWER SUPPLY CIRCUITS, SIGNAL CIRCUITS, AND GROUND CIRCUITS FOR OPEN CIRCUIT •  Inspect the applicable circuit for open circuit. (See CIRCUIT INSPECTION.) •  Is the circuit normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1.
7	PURPOSE: VERIFY IF REVOLUTION SENSOR IS INSTALLED CORRECTLY •  Verify the revolution sensor installation condition. (See REVOLUTION SENSOR REMOVAL/INSTALLATION [C66M-R, C66MX-R].) •  Is the installation condition normal?	Yes	Go to the next step.
		No	Correctly install the revolution sensor and perform the repair completion verification 1. (See REVOLUTION SENSOR REMOVAL/INSTALLATION [C66M-R, C66MX-R].)
8	PURPOSE: INSPECT REVOLUTION SENSOR FOR MALFUNCTION •  Inspect the applicable part. (See REVOLUTION SENSOR INSPECTION [SKYACTIV-D 1.8].) •  Is the part normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location and perform the repair completion verification 1. (See REVOLUTION SENSOR REMOVAL/INSTALLATION [C66M-R, C66MX-R].)
9	PURPOSE: INSPECT MANUAL TRANSAXLE FOR MALFUNCTION DEPENDING ON REPEATABILITY •  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	Replace the manual transaxle and perform the repair completion verification 1. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [C66M-R (SKYACTIV-D 1.8)].)
		No	Go to repair completion verification 2.
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 [(E)].) 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 [SKYACTIV-D 1.8].)
		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.
		No	DTC troubleshooting completed.
