Safety Precautions: Notes
Note the following when working on the fuel system:
There is a risk of injury because the fuel is under very high pressure.
- Before opening high pressure components of the fuel injection system, pressure must be relieved to residual pressure.
- To reduce residual pressure, lay a clean cloth around the connector and carefully loosen connector.
-- Procedures before opening high pressure fuel injection system, refer to BEFORE OPENING HIGH PRESSURE FUEL INJECTION SYSTEM .
To prevent personal injury and damage to the injection and ignition system, observe the following:
- The ignition must be switched off before connecting or disconnecting injection and ignition system wiring or tester cables.
- Wash the engine only when the ignition is turned off.
- If electrical connectors were disconnected, faults are saved in ECM:
-- Connect Vehicle Diagnostic Tester.
-- Start "Guided Functions " operating mode.
-- Generate readiness code in ECM.
Danger of causing damage to other electronic components when disconnecting the battery.
- Complete the steps for disconnecting the battery.
- Always turn off the ignition before disconnecting the battery.
-- Disconnect the Battery, refer to BATTERY, DISCONNECTING AND CONNECTING .
Risk of scalding due to hot steam and hot coolant.
- The coolant system is under pressure when the engine is warm.
- Cover the coolant reservoir cap with a cloth and then open it slowly to release the pressure.
If testing equipment must be used during a road test, observe the following:
Distraction and testing equipment that is not secured properly can cause accidents.
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 testing equipment on the rear seat with a strap and have a second person on the rear seat operate them.
