All
Yes
→ Go To 4
No
→ Repair the ground circuit for an open.
Perform VTSS VERIFICATION TEST - 1A.
4
With the VTSS Siren connector disconnected.
Turn the ignition on.
Measure the voltage of the Siren Signal Control circuit (cavity 2) in the VTSS Siren
connector.
Is the voltage approximately 5.0 volts +/- 1.0 volt?
All
Yes
→ Replace the VTSS Siren.

VEHICLE THEFT/SECURITY
*VTSS SIREN INOP (EXPORT ONLY) —
Continued
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.
Perform BODY VERIFICATION TEST - VER 1.

VEHICLE THEFT/SECURITY
Symptom:
FR WIPER HI-LO RELAY OPEN
POSSIBLE CAUSES
FUSED B(+) CIRCUIT
COMMON CIRCUIT OPEN
WIPER HI/LOW RELAY
WIPER ON/OFF RELAY
WIPER HI/LOW RELAY CONTROL CIRCUIT OPEN
FCM-ON/OFF RELAY DRIVER OPEN
TEST
ACTION
APPLICABILITY
1
Turn the ignition off.
Remove the Wiper On/Off Relay from the PDC.
Using a 12-volt test light connected to ground, probe both Fused B(+) circuits in the
PDC.
NOTE: The test light must illuminate brightly. Compare the brightness to
that of a direct connection to the battery.
Does the test light illuminate brightly at each terminal?
All
Yes
→ Go To 2
No
→ Repair the Fused B(+) circuit(s) for an open.
Perform BODY VERIFICATION TEST - VER 1.
2
Install a substitute relay in place of the Wiper On/Off Relay.
Turn the ignition on.
Turn the wipers on.
Does the system operate correctly?
All
Yes
→ Replace the Wiper On/Off Relay.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 3
3
Turn the ignition off.
Remove the wiper High/Low Relay from the PDC.
Remove the wiper On/Off Relay from the PDC.
Measure the resistance of the Common circuit between the High/Low Relay and the
On/Off relay in the PDC.
Is the resistance below 10.0 ohms?
All
Yes
→ Go To 4
No
→ Repair the Common circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
4
Install a substitute relay in place of the Wiper Hi/Low Relay.
Turn the ignition on.
Turn the wipers on.
Does the system operate correctly?
All
Yes
→ Replace the Wiper Hi/Low Relay.
