ACTION

APPLICABILITY

1

With the DRBIII

t, actuate the VTSS Siren.

Does the Siren sound while actuating?

All

Yes

→ The condition that caused this symptom is currently not present.

Inspect the related wiring harness for a possible intermittent
condition. Look for any chafed, pierced, pinched or partially
broken wires.
Perform VTSS VERIFICATION TEST - 1A.

No

→ Go To 2

2

Gain access to the VTSS Siren.
Disconnect the VTSS Siren connector.
Turn the ignition on.
Measure the voltage of the Siren Supply circuit (cavity 3) in the VTSS Siren
connector.
Is the voltage above 10.0 volts?

All

Yes

→ Go To 3

No

→ Go To 9

3

With the VTSS Siren connector disconnected.
Measure the resistance of the Siren Signal Return circuit to ground.
Is the resistance below 5.0 ohms?

All

Yes

→ Go To 4

No

→ Go To 7

5

Gain access to the Thatcham Alarm Module 16-way harness connector.
While back probing, measure the voltage of the Siren Signal Control circuit.
Turn the ignition on.
Is the voltage approximately 5.0 volts?

All

Yes

→ Go To 6

No

→ Replace the RKE/Thatcham Alarm Module.

Perform VTSS VERIFICATION TEST - 1A.

6

Disconnect the Thatcham Alarm Module 16-way harness connector.
Measure the resistance of the Siren Signal Control circuit between the Thatcham
Alarm Module and the VTSS Siren connectors.
Is the resistance below 5.0 ohms?

All

Yes

→ Replace the VTSS Siren.

Perform VTSS VERIFICATION TEST - 1A.

No

→ Repair the Siren Signal Control circuit for an open.

Perform VTSS VERIFICATION TEST - 1A.

7

Gain access to the RKE/Thatcham Alarm Module.
While back probing, measure the resistance of the Siren Signal Return circuit in the
Thatcham Alarm Module 16-way connector.
Is the resistance below 5.0 ohms?

All

Yes

→ Go To 8

No

→ Replace the RKE/Thatcham Alarm Module.

Perform VTSS VERIFICATION TEST - 1A.

8

Disconnect the Thatcham Alarm Module 16-way harness connector.
Measure the resistance of the Siren Signal Return circuit between the Thatcham
Alarm Module and the VTSS Siren connector.
Is the resistance below 5.0 ohms?

All

Yes

→ Replace the VTSS Siren.

Perform VTSS VERIFICATION TEST - 1A.

No

→ Repair the Siren Signal Return circuit for an open.

Perform VTSS VERIFICATION TEST - 1A.

9

Gain access to the RKE/Thatcham Alarm Module.
While back probing, measure the voltage of the Siren Supply circuit in the Thatcham
Alarm Module 16-way connector.
Turn the ignition on.
Is the voltage above 10.0 volts?

All

Yes

→ Go To 10

Symptom:

*VTSS WILL NOT ARM

POSSIBLE CAUSES

CHECK THE VTSS STATUS

CHECK FOR BCM DTCS AND VTSS ARMING INHIBITORS

CHECK FOR PCI BUS COMMUNICATION OF INSTRUMENT CLUSTER AND SKIM

BODY CONTROL MODULE

TEST

ACTION

APPLICABILITY

1

With the DRBIII

t in BCM, select Miscellaneous Function and check that the Theft

Alarm is enabled.
Was the Theft Alarm enabled?

All

Yes

→ Go To 2

No

→ With the DRBIIIt, enable the Vehicle Theft Security System

(VTSS).
Perform VTSS VERIFICATION TEST - 1A.

2

With the DRBIII

t, attempt to read the Module Display of the Instrument Cluster and

also the Sentry Key Immobilizer Module.
Was the DRBIII

t able to display the module information of the MIC and SKIM?

All

Yes

→ Go To 3

No

→ Refer to the Symptom List and diagnose the appropriate symptom

in the Communication category.
Perform VTSS VERIFICATION TEST - 1A.

3

Ensure all doors and hood (export only) are closed.
With the DRBIII

t, read the active DTC’s and the ajar switch states.

Does the DRBIII

t display any closed switches or VTSS related DTC’s?

All

Yes

→ Refer to the Symptom List and diagnose the appropriate symptom

in the DOOR AJAR or VTSS category.
Perform VTSS VERIFICATION TEST - 1A.

No

→ Replace the Body Control Module.
