INFORMATION
An enhancement to the existing Automatic TeleService Calls (ASC) is the introduction of event-triggered calls, based on the ability of the battery to start the vehicle. An Automatic TeleService Call is sent out based on the state of charge of the battery.
There are two situations that might occur in the vehicle to trigger a call:
1. The minimum state of charge of the battery necessary for the vehicle to start has not been reached yet, but if the situation is not corrected right away the vehicle may not start. This situation is caused by the lights (parking or side marker) being left on after the vehicle is parked. This triggers an immediate call to the center. The center can then contact the customer and inform him or her to turn off the lights so the vehicle will be able to start.
2. The minimum state of charge of the battery in order for the vehicle to start has been reached and the vehicle may not start. This situation is caused by a vehicle fault (excessive closed circuit current draw, sleep mode prevented, frequent wakeups or undetermined causes). A TeleService call will be triggered the next time the vehicle is started. The center can then contact the customer and request an appointment in order to troubleshoot the problem before the battery is discharged and the vehicle's ability to start is affected.
However, in many cases, the underlying reason for reaching the low battery state of charge is more subtle and cannot be diagnosed by the transmitted information. In these cases, the center receives a notification about the case, but is also informed that a further analysis is not possible without actual diagnosis on the vehicle using ISTA (Integrated Service Technical Application).
Please be sure to review the Appointment Screen to determine the appropriate steps in handling the TeleService request (see the attachment for an example).
