Multiport Fuel Injection

Safety Precautions

If testing equipment must be used during a road test, observe the following:

Improperly secured testing and measuring equipment and distraction during a road test increase the risk of an accident.

The passenger airbag could pose a risk if it deploys in a collision.

• Operating testing equipment while driving causes it to shift position.

• There is an increased risk of injury due to unsecured testing equipment.

• Always secure testers on the rear seat with a strap and have a second person on the rear seat to operate them.

• Always follow the instructions when disconnecting the battery.

Note the following when working on the fuel system:

There is a risk of injury because the fuel is under very high pressure.

• The fuel pressure must be reduced to residual pressure before opening the high pressure area of the fuel injection system. Refer to => [ Releasing Pressure in High Pressure Area ] Releasing Pressure In High Pressure Area.

• To reduce remaining residual pressure, place a clean cloth around the connector and carefully loosen the connector.

- Procedures before opening the high pressure fuel injection system. Refer to => [ Releasing Pressure in High Pressure Area ] Releasing Pressure In High Pressure Area.

To prevent personal injury and damage to the injection and ignition system, observe the following:

• Individuals with a pacemaker must not stay in the danger area of high voltage systems, for example ignition systems, xenon light.

• Turn off the ignition before disconnecting and connecting the wiring for the injection and ignition system. This includes tester cables as well.

• Fuel lines must not be opened when the engine is running.

• Only clean the engine with the ignition turned off.

• While testing it is possible that there may be some faults stored in the Engine Control Module (ECM). After completing all testing and repairs, check the Diagnostic Trouble Code (DTC) memory. If a fault has been stored:
