Telematics Indicator Lamp (K186), Malfunction Recognition
The following descriptions are for initial malfunction recognition with the OnStar Telematics indicator lamp.
Detailed fault finding is only possible using the Vehicle Diagnosis, Testing and Information System (VAS 5051B ) in the "Guided Fault Finding" mode.
A Telematics indicator lamp in the form of an LED is installed in the Telematics Control Head (E264). LED indications are red or green, blinking quickly or slowly.
Depending on the status of the Telematics system, activation of the Telematics indicator lamp with the ignition switched on corresponds to the following table:
Further Information
• If the ignition is off, the Telematics indicator lamp is also off.
• After ignition is switched on, self-check routine is performed in Telematics system. The green LED illuminates after approximately 15 seconds if no malfunctions are identified. System is now ready to send or receive calls. The green LED continues to illuminate if no reception is possible in certain areas.
• If the green LED flashes slowly, a communication request has been initiated and the system is in the process of establishing a connection.
• If the LED illuminates red, a malfunction was found during the self-check or the system performed a faulty function.
• After the OnStar or Emergency button is pushed, the message: "connecting to OnStar" is issued, followed by a sequence of tones. Normal connection time is 10 to 15 seconds. However, connection time can be up to three minutes, depending on reception conditions. Be patient.
The Telematics indicator lamp illuminates green and the following message can be heard:
• Message Unable to contact OnStar, connection is interrupted.
• Message OnStar request ended
• Cellular network message is heard
• nothing happens
All previous points indicate an issue with cellular reception.
Proceed as follows: Drive vehicle to more elevated or open area repeat connection attempt. Depending on local conditions, it is possible - and normal - that several connection attempts are necessary.
Malfunctioning antenna system of vehicle also affects connectivity. If necessary conduct fault finding for the antenna system with the Vehicle Diagnosis, Testing, And Information System (VAS 5051B) in the "Guided Fault Finding" mode.
If there is still no connection, write down the VIN and customer data. Call OnStar service at: 1-888-390-4050. Identify yourself to OnStar Service as a Volkswagen technician. OnStar Service will check and confirm that the customer account is active. Further troubleshooting assistance may be given.
The Telematics indicator lamp illuminates red.
Indicates fault on vehicle side. Proceed as follows:
Use on board diagnostic with the Vehicle Diagnosis, Testing And Information System (VAS 5051B) in the "Guided Fault Finding" mode.
• If any Telematics button in the Telematics Control Head (E264) is pressed either inadvertently or deliberately for longer than 15 seconds, on board diagnostic assumes that a button is sticking. The red LED illuminates and the malfunction 01526 - mechanical malfunction is stored in the DTC memory. Make sure buttons are fully operable, erase DTC and inform customer.
