repair of a car fault has been performed correctly.

6.2.2 Read Live Data

This function retrieves and displays live data and parameters from the

vehicle's ECU.

This function takes the snapshot of the operating conditions when an

emission-related fault occurs.

This function can identify which section of the emission control system has

malfunctioned.

Note: Retrieving and using DTCs for troubleshooting vehicle operation is only

one part of an overall diagnostic strategy. Never replace a part based only on the

DTC definition. Each DTC has a set of testing procedures, instructions and flow

charts that must be followed to confirm the location of the problem. This information

can be found in the vehicle's service manual.

This function erases the codes from the vehicle, after retrieving codes from the

vehicle and certain repairs have been carried out.

Make sure the vehicle's ignition key is in the ON position with the engine off

before the operation.

Notes:

1. If you plan to take the vehicle to a Service Center for repair, DO NOT erase the

codes from the vehicle's computer. If data is erased, valuable information that

might help the technician troubleshoot the problem will also be erased.

2. Clearing DTCs does not fix the problem(s) that caused the code(s) to be set. If

proper repairs to correct the problem that caused the code(s) to be set are not

made, the code(s) will appear again and the check engine light will illuminate as

soon as the problem that cause the DTC to set manifests itself.

This function retrieves test results for emission-related powertrain components

and systems that are not continuously monitored. The test's availability is

determined by the vehicle manufacturer.
