Mazda 2: Before/After Service

BEFORE SERVICE PRECAUTION

WARNING:

• Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage.

  Always keep sparks and flames away from fuel.

• Fuel line spills and leakage from the pressurized fuel system are dangerous. Fuel can ignite and cause serious injury or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Line Safety Procedure".
• 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.

CAUTION:

• If there is foreign material on the connecting area of the quick release connector, it might damage the connector or fuel pipe. To prevent this, disconnect the connector and clean the connecting area before connecting.

Fuel Line Safety Procedure

1. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION).

2. Remove the fuel-filler cap to release the pressure inside the fuel tank.

3. Remove the fuel pump relay.

4. Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION).

5. Start the engine.

6. After the engine stalls, crank the engine 2-3 times.

7. Switch the ignition to off.

8. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION).

9. Install the fuel pump relay.

10. Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION).

AFTER SERVICE PRECAUTION

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. (See 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. (See BATTERY REMOVAL/INSTALLATION).

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. (See BATTERY REMOVAL/INSTALLATION).

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.
