Condition

Some technicians may comment that after the GM Accessory Interior
Spectrum Lighting Kit (commonly referred to as the Interior Ambient
Lighting Kit or the Interior Accent Lighting Kit) the lighting is
inoperative. The purpose of this Preliminary Information is to provide
dealership technicians some tips on installation of this kit, as well as
some common areas to check if the system is inoperative after
installation is completed.
The Interior Spectrum Lighting kit is a GM Accessory kit that allows
color changing lighting to be installed inside the vehicle. The system
is capable of producing 24 different colors. There are three different
types of Lighting kits listed below that may be installed in the 6th
generation (2016+) Camaros, so it is very important to know which kit
is being installed.
1) Light up Accent Lighting on the door panels only

2) Footwell Lighting only

3) Light up Accent Lighting on the door panels AND Footwell Lighting
IMPORTANT: All Camaros have a light pipe around the radio display,
as seen in the photo below. When installing a GM Accessory Lighting
Kit on a vehicle that is NOT equipped with the factory C70 RPO, the
light strip around the radio display will illuminate white, and it can
not be changed or controlled. This is normal. There will not be a
color changing light in this kit for the center cupholder either. The
only way to get these two lights to operate in a controlled manner is
to purchase the vehicle with the factory C70 RPO.
Again, the GM Accessory Interior Spectrum Lighting kit will not
provide illumination for the cupholders, nor will the built-in light pipe
that surrounds the radio display be able to be changed or controlled

as far as color goes. It will illuminate with a white appearance, no
matter what.

Installation Tips:
The first thing that needs to be done when installing any GM
Accessory kit, is to have the Parts Department contact Partech, obtain
a case number, and verify that the kit being installed is the correct
one for the VIN in question. Many kits looks similar, but are only
intended for specific options or RPOs. If the incorrect kit is installed
on a vehicle, it will result in much frustration and wasted time by the
technician.

Along with each of the three types of Light Kits, each kit comes in
several different trim colors as well. These are currently available in
silver, black, and red. In addition to that, which kit is needed depends
on the radio that the vehicle is equipped with. As you can see,
obtaining the correct kit PN is crucial for a smooth, trouble-free
installation.
Once the correct kit has been verified through Partech, determine
which of the three types of Lighting Kits you will be installing. Then,
refer to SI and read through the instructions. These are broken up in
sections based on which kit is being installed.
IMPORTANT: NOTE - Be sure that the correct section of the
installation instructions is being followed for the type of kit that is
being installed.

One question that consistently comes up during the installation of
this kit, is regarding steps 25-31. On many vehicles, it may be noted
that there are already wires present in the side body-to-door
connectors (X500 or X600) in cavities 42 and 43. This is not a mistake
or a misbuild. These wires have been inserted in these cavities on
purpose. To complete the installation of this GM Accessory kit, simply
remove these two existing circuits from the connector in question,
tape them up, and secure them out of the way. Then, continue
installing the wires from the Accessory kit as directed.

Troubleshooting Tips:
If the Lighting Kit is inoperative upon installation, the following items
should be inspected:
If the entire kit has been installed and the lighting is entirely
inoperative, there are a few things to go back and check. The
most common area for concern is G202, which is located at the
right hand kick panel. Typically, this ground has paint on it when
the kit's eyelet is installed. Just tightening the fastener does not
provide a good ground path if there is still paint covering the
sheet metal. The fastener will have to be removed, the paint
needs to be cleaned or ground off, and the ground path verified.

There are 3 circuits that are spliced or plugged into the BCM
related wiring. One of the circuits in the kit has a blunt cut end
and must be tapped into the dash wiring going to the BCM. The
two other wires have terminals crimped on the end and they are
supposed to be inserted into empty BCM connector cavities. A
common installation error is to install either of these circuits into
the incorrect connector cavity. Either one of these terminals can
easily be installed accidentally into an adjacent BCM connector
cavity.
Another common issue that is seen relates to the Posi-Tap
connectors used in the kit. These connectors are used to splice
the accessory harness to the vehicle's wiring harness.
Dealership technicians are to go back through the installation
and verify that each connector is tight. If one or more of these
connecters is/are loose, this will cause any number of
performance issues with the kit. The connector shown in the
photo below does not have tape or a zip tie covering it for clarity.
Once the connector is properly installed, the instructions have
the technician tape back the splice to the main harness using
cloth tape. This will prevent the connector from loosening up
over time.

If the vehicle is equipped with an "uplevel" radio (RPOs IO5, IO6,
IOS, or IOT) various modules will require reprogramming through
Techline. This programming allows the customer to select the
various lighting colors on the radio's touchscreen, as seen in the
color palette photo below. As seen in the second photo below,
there will also be a sheet of paper included in the kit that has an
authorization code printed on it. Once that code is provided to
Techline, they will be able to assist in correctly programming the
vehicle.
For the 2016 - 2018 models with the IO5 or IO6 radio, the HMI and the BCM will
require SPS programming.
For the 2019+ models with the IOS or IOT radio, the radio and BCM will require
SPS programming.

Vehicles equipped with the base radio (RPO IOB or IOR) do not
require any programming. That is why the color selections are
not available on the radio screen. This system uses a dashmounted switch to change the system's lighting colors. It is
installed on the left hand side of the steering column. This
switch can be seen in the photo below.
If a kit is being installed on a vehicle with either the IOB or the IOR
base level radios, and TCSC has provided any type of a calibration for
the kit, STOP, and do not proceed any further. Contact TCSC again
and request all cals be returned to OEM configuration as it relates to
this kit. Under no circumstances should BCM, HMI, or radio
calibrations be changed from factory cals in regards to the
installation of this Interior Spectrum Lighting kit.
