VTSS/SKIS INDICATOR LAMP
DESCRIPTION
The Sentry Key Remote Entry System (SKREES)
uses an indicator light to convey information on the
status of the system to the customer. This light is
shared with the Vehicle Theft Security System
(VTSS). The light is located in the Mechanical
Instrument Cluster (MIC). The VTSS status is controlled
by the Body Control Module (BCM), via Programmable
Communication Interface (PCI) data bus
communication with the MIC, based upon messages
it receives from the Sentry Key Remote Entry Module
(SKREEM) on the PCI data bus.
OPERATION
The Mechanical Instrument Cluster (MIC) performs
a four second bulb check via PCI communication
with the Sentry Key Remote Entry Module
(SKREEM). After the bulb check, the lamp is controlled
according to SKREEM messages. Then, the
SKREEM sends messages to the BCM to operate the
light based upon the results of the Sentry Key
Remote Entry System (SKREES) self tests. The light
may be actuated in two possible ways, flashing or on
solid. If the light comes on and stays on solid after a
power-up test, this indicates that the SKREEM has
detected a system malfunction. If the SKREEM
detects an invalid key when the ignition switch is
moved to the ON position, it sends a message on the
PCI bus to the MIC, to flash the light. The SKREEM
can also send a message to flash the light and generate
a single audible chime at the same time. These
two events occurring simultaneously indicate that
the SKIS has been placed into the 9Customer Learn9
mode (Refer to 8 - ELECTRICAL/VEHICLE THEFT
SECURITY/TRANSPONDER KEY - STANDARD
PROCEDURE). If the light comes on and stays on
after the power-up test, diagnosis of the SKREES
should be performed using a DRBIIIt scan tool and
the appropriate Body Diagnostic Procedures information.
The light is a Light Emitting Diode (LED) and
is not a serviceable component.


It is staying solid for me... where do I get a DRBIII scan tool cheep? Thanks all

 

Get a DRBIII cheap? You don't. They costs upwards of $1500+. The only way to proceed I know of is to read the codes causing the failure and follow the prescribed troubleshooting tree as a dealership would or inspect connections and wire harnesses or start swapping parts as we would. Trouble is the DRBIII is needed to set the security codes in the parts. Have you tried posting your problem on the other forums I suggested? I sure don't have a knowledge monopoly on these vans. Somebody may have a solution I'm not aware of.

Tizzy1, Steak59 and Master Tech are very knowledgeable techs on this forum. No doubt I'm forgetting others and my apologies to them. Give them a little nudge with a private message. Keep us posted.
