Fuel Delivery and Air Induction: Testing and Inspection

AFTER SERVICE PRECAUTION [LF, L5]

WARNING:
- Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. When installing the fuel hose, perform "Fuel Leakage Inspection" described below.
- A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before performing work on the fuel system, discharge static electricity by touching the vehicle body.

Fuel Leakage Inspection

CAUTION:
- Connecting to the wrong check connector terminal may cause a malfunction. Carefully connect only to the specified terminal.

Using M-MDS

1. Connect the M-MDS to the DLC-2.






2. Switch the ignition to ON.

3. Using the simulation function "FP", start the fuel pump. On-Board Diagnostic Test

4. Verify that there is no fuel leakage from the pressurized parts.

Standard
- There shall be no leakage after 5 min.

5. In the case of fuel leakage, replace the following components and then do the recheck by the fuel leakage checking procedure.

- If there is leakage, replace the fuel hoses and clips.
- If there is damage on the seal on the fuel pipe side, replace the fuel pipe.

Without using M-MDS

1. Disconnect the negative battery cable.

2. Remove the fuel pump relay.






CAUTION:
- Short the specified terminals because shorting the wrong terminal of the relay and fuse block may cause malfunctions.

3. Using a jumper wire, short fuel pump relay terminals C and D in the relay and fuse block.






4. Connect the negative battery cable and operate the fuel pump.

5. Verify that there is no fuel leakage from the pressurized parts.

Standard
- There shall be no leakage after 5 min.

6. In the case of fuel leakage, replace the following components and then do the recheck by the fuel leakage checking procedure.

- If there is leakage, replace the fuel hoses and clips.
- If there is damage on the seal on the fuel pipe side, replace the fuel pipe.
