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.
