TeleAid Runaway
If you receive customer reports in the above model vehicles of TeleAid Runaway, please note a TeleAid "Runaway" is defined as a vehicle that has the TeleAid control unit perform either Alarm Activation Notification (AAN) or Remote Door Unlock (RDU) calls more than 10 times per day. In most of these cases, fault is found with components other than the TeleAid. For example, a runaway that is making RDU calls might have a malfunctioning trunk latch, or a short in the SAM.
The following is a method to determine the root cause for TeleAid runaways. It is always helpful to determine the type of runaway signal that the vehicle was transmitting. The only two options are Alarm Activation Notification (AAN), or Remote Door Unlock (RDU). If the runaway status of the vehicle is not known, then obtain the Mobile Identification Number (MIN), Electronic Serial Number (ESN), and VIN, and call the ATX Call Center at 800-756-9018. When you provide this vehicle specific information, the call center representative will be able to provide you with the type of signal and the occurrence of each signal.
I. HOW TO DETERMINE LAST TRIGGERED ALARM SIGNALS:
In some models, Star Diagnosis can be used to determine what anti-theft alarm components triggered the most recent AANs. Other models list the real-time current status of the alarm and door contacts. Use the following tables to determine what device triggered the alarm, or what device is being activated.
The "ATA alarm sources" page will list the last 5 alarm activations along with the description of the component that caused the alarm activation. If in the last 5 activations there is a high frequency of one particular component, then it is very probable that component or its circuitry is responsible for the activations.
The "Actual Values" and Central locking" page will list the real4ime current status of the ATA contact switches. This can help determine if a switch is being activated inadvertently.
II. HOW TO DETERMINE REMOTE DOOR UNLOCK MALFUNCTION USING DAS:
Star Diagnosis can also be used to determine if an unwarranted RDU signal is being transmitted. Use the following table to determine the actual value of the trunk latch or button. For models 170, 208, and 210, use the List of Actual Values" table shown above. There is no information for the trunk lid on 209.
Observe the status of the switches. If problem is intermittent, then manipulate switch and/or wiring in order to provoke failure. If any of the Actual Values register as OPERATED or ON, while the trunk is closed, then further inspection is required of the trunk latch assembly.
III. DIAGNOSIS USING WIS DOCUMENTATION:
There are many components in the anti-theft alarm (ATA) system connected with the TeleAid control unit. There is the case where any one of these components could become faulty and cause an unwarranted AAN signal to the TeleAid control unit. The following WIS documentation lists information regarding the anti-theft alarm (ATA) system in different models. These control units can be found in WIS under group 80.50: Anti- theft alarm system (ATA), interior motion sensor/Tow sensor for all models. Here are more specific documents found in group 80.50:
IV. SUPPLEMENT FOR RDU DIAGNOSIS
In all of these documents, it is possible to find the trunk latch/button. Not only is this a component of the ATA, but it also responsible for the triggering of a Remote Door Unlock. The following table lists all the trunk latch/button respective to all models taken from the WIS documentation. The trunk latch/button should be the FIRST component diagnosed. Use this in RDU cases:
V. DETECTING DISCRETE RDU AND AAN SIGNALS FROM TELEAID CONNECTOR:
Note:
The following method only apples to vehicles with TeleAid 2 units. All vehicles with a CP (e.g. 211) only transmit RDU and AAN signals via CAN).
The table describes the type of signals used to communicate the RDU and AAN signals to the TeleAid control unit:
^ If the vehicle supports a discrete signal for AAN, a 12V signal to pin 32 on the TeleAid control unit will trigger a call for an alarm notification.
^ If the vehicle supports a discrete signal for RDU, a 0V signal to pin 41 on the TeleAid control unit will trigger a call for a remote door unlock request.
Some models support CAN messages to the TeleAid control unit for both RDU and AAN.
