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 display
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.
4.9 Generic OBD II Operations
A fast-access option for OBD II/EOBD vehicle diagnosis is available on the
Vehicle Menu screen (Figure 4-2). 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 OBD II/EOBD compliant vehicles
that are not included in the Diagnostics database.
Functions of the diagnostics toolbar buttons at the top the screen are the
same as those available for specific vehicle diagnostics. See Table 4-2
Diagnostics Toolbar Buttons on page 31 for details.
