WARNING: 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.

C. Clear Fault Code

After reading the retrieved codes from the vehicle and certain

repairs have been carried out, you can use this function to

erase the codes from the vehicle. Before performing this

function, please be sure the vehicle’s ignition key is in the

ON position with the engine off.

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.

In Fig. 5-23, tap on “Clear Fault Code”, a conﬁrmation dialog

box pops up on the screen. Tap on “Yes” and the system will

automatically delete the currently existing trouble code.

Note: After clearing, you should retrieve trouble codes

once more or turn ignition on and retrieve codes again. If

there are still some trouble codes in the system, please

troubleshoot the code using a factory diagnosis guide, then

clear the code and recheck.

D. Read Data Stream

This option lets you view and capture (record) real-time

Live Data. This data including current operating status for

parameters and/or sensor information can provide insight

on overall vehicle performance. It can also be used to guide

vehicle repair.

DANGER: If you must drive the vehicle in order to perform a

troubleshooting procedure, ALWAYS have a second person

help you. Trying to drive and operate the diagnostic tool

at the same time is dangerous, and could cause a serious

trafﬁc accident.

In Fig. 5-23, tap on “Read Data Stream”, the system will

display data stream items.
