The main section of the reprogramming interface provides you certain hardware version,
and current software versions’ information, as well as the information of the newest
software versions to be programmed to the control units.
Throughout the programming procedure, a series of on-screen operational instructions
will display to guide you through.
Carefully read the on-screen information and follow the instructions to execute the
programming procedure.
Re-flash Errors
IMPORATANT
When reprogramming onboard, always make sure the vehicle battery is fully charged
and in good working condition. During reprogramming, there is a risk of having the
operation failure if voltage falls below the proper operation voltage. Sometimes a failed
operation can be recovered, but there is a chance that failed reprogramming could ruin
the control module. We recommend connecting an external battery charger to the vehicle
to ensure a successful operation.
Occasionally a flash update procedure may not complete properly. Common causes of
flash errors include poor cable connections between the tablet, VCI, and vehicle, turning
off the vehicle ignition switch before the flash procedure is complete, or low vehicle
battery voltage.
If the process crashes, recheck all the cable connections to assure good communications
and reinitialize the flash procedure. The programming procedure will automatically repeat
if the previous operation does not succeed.
Generic OBDII Operations
A fast-access option for OBDII/EOBD vehicle diagnosis is available on the Vehicle Menu
screen. This option presents a quick way to check for DTCs, isolate the cause of an
illuminated Malfunction Indicator Lamp (MIL), check monitor status prior to emissions
certification testing, verify repairs, and perform a number of other services that are
emissions-related. The OBD direct access option is also used for testing OBDII/EOBD
compliant vehicles that are not included in the diagnostics database. Functions of the
diagnostics toolbar buttons at the top of the screen are the same as those available for
specific vehicle diagnostics. See
Table 4-2 Diagnostics Toolbar Buttons on page 27 for
details.
General Procedure
