DIAGNOSTIC PROCEDURE - FUNCTION INSPECTION USING M-MDS
| STEP |
INSPECTION |
RESULTS |
ACTION |
| 1 |
PURPOSE: VERIFY RELATED REPAIR INFORMATION AVAILABILITY
- Verify related Service Bulletins and/or on-line repair information availability.
- Is any related repair information available?
|
Yes |
Perform repair or diagnosis according to the available repair information.
- If the vehicle is not repaired, go to the next step.
|
| No |
Go to the next step. |
| 2 |
PURPOSE: RECORD FREEZE FRAME DATA/SNAPSHOT DATA AND DIAGNOSTIC MONITORING TEST RESULTS TO UTILIZE WITH REPEATABILITY VERIFICATION
NOTE:
- Recording can be facilitated using the screen capture function of the PC.
- Record the FREEZE FRAME DATA/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS (EVAP system related) on the repair order.
|
- |
Go to the next step. |
| 3 |
PURPOSE: VERIFY IF FUEL GAUGE SENDER UNIT HAS MALFUNCTION
- Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST
).
- Is the PENDING CODE/DTC P0460-00:, P0461-00:, P0462-00: or P0463-00: also present?
|
Yes |
Perform the DTC troubleshooting for the fuel gauge sender unit first because the fuel gauge sender unit cannot detect the fuel tank level and determines that a malfunction is occurring.
(See DTC P0460-00:
).
(See DTC P0461-00:
).
(See DTC P0462-00:
).
(See DTC P0463-00:
). |
| No |
Go to the next step. |
| 4 |
PURPOSE: VERIFY FUEL TANK PRESSURE SENSOR MEASURED CORRECTLY
- Start the engine and idle it.
- Access the following simulation items using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST
).
- Change to the following conditions using the simulation function.
- Access the FTP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST
).
- Does the negative pressure change when racing the engine?
|
Yes |
The fuel tank pressure sensor measures correctly.
|
| No |
The possibility of a fuel tank pressure sensor malfunction is high.
- Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
|
| 5 |
PURPOSE: VERIFY IF PURGE SOLENOID VALVE IS STUCK OPEN
- Perform the following procedure to induct barometric pressure to the fuel tank.
- EVAPCP
- Change to the following conditions using the simulation function.
- EVAPCP: 0 %
NOTE:
- The displayed PID value is as follows:
- Approx. 2.6 V (barometric pressure)
- Perform the following procedure to force drive the CV solenoid valve.
- Access the following simulation items using the M-MDS: (See ON-BOARD DIAGNOSTIC TEST
).
- EVAPCP
- Change to the following conditions using the simulation function.
- EVAPCP: 0 %
- Is the FTP PID value negative pressure?
|
Yes |
The possibility of a stuck purge solenoid valve open is high.
- Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 2.
|
| No |
The possibility of clogging between fuel tank pressure sensor and fuel tank is high.
- Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 3.
