Telematics system, troubleshooting 
using telematics indicator lamp 

 

  

   The following allows technicians to perform 

an initial evaluation of Telematics system 
operation status for troubleshooting using 
the OnStar

telematics indicator lamp (and 

pre-recorded system messages where 
applicable).  

  

   This serves only as an initial evaluation 

only and is not meant to supercede 
detailed OBD program procedures 
carried out with VAS 5051 Vehicle 
Diagnostic Testing and Information 
System in operating mode "Guided Fault 
Finding". 

  

   The telematic indicator lamp LED is located 

in the telematic control head. LED 
indications are red or green, lighting 
continuously, blinking slowly or quickly.  

  

   Telematic system status can be determined 

via the LED with the ignition switched on and 
referenced from the following table:

LED indication  

System status:  

Off  

No connection, no malfunction  

Red - contiuously  

No connection, malfunction in telematics hardware  

Green -continuously  

After completion of self-test or when OBD program is 

performed  

Red - blinking slowly  

Establishing connection, malfunction in telematics hardware  

Red - blininking 
quickly  

Connection active, malfunction in telematics hardware  

Green - blinking slowly   Establishing connection, no malfunction  

Green - blinking 
quickly  

Connection active, no malfunction  

  

   Indications, overview: 

  

  

 LED is off when ignition is off. 

  

  

 The green LED comes on after a self-check 

routine is performed (approx. 10- 15 seconds 
after ignition is switched on). Sending or 
receiving voice communication with the 
OnStar

call center is now possible. LED 

remains on even in areas without cellular 
coverage. 

  

  

 The green LED slowly blinking indicates a 

communication request has taken place and the 
system is in the process of establishing a 
cellular connection. 

  

  

 The red LED indicates a malfunction in the 

telematics hardware was determined during the 
self check.

   Note:  

  

   After pressing either the OnStar

 or Emergency 

button, a recorded message announces: 
"connecting to OnStar," followed by progression 
tones. Normal connection time is 10 - 15 
seconds. However, due to local cellular/GPS 
conditions, making a connection could take up to 
three minutes. Be patient. 

  

   Condition - telematics indicator lamp "green" 

plus:  

  

  

 message "unable to contact OnStar

" and 

disconnect, 

  

  

 message "OnStar

request ended", 

  

  

 nothing happens, 

  

  

 or a cellular message 

  

   indicates system cellular reception is affected. 

Proceed as follows:  

  

  

-  Relocate vehicle to a more elevated or open 

area and repeat connection attempts. 
Depending on the local cellular/GPS traffic 
conditions, several connection attempts may be 
necessary (and are normal). 

  

  

-  Shortcomings in the vehicle's cellular/GPS 

antenna system also affects connectivity. Check 
all cellular/GPS antenna connections, and 
perform OBD program using VAS 5051 Vehicle 
Diagnostic Testing and Information System in 
mode "Guided Fault Finding". Check for DTCs 
related to antenna function.
