SIREN
TEST
ACTION
APPLICABILITY
1
With the DRBIII
t, record and erase DTC’s.
Remove the ignition key.
Close and lock all doors and set the Vehicle Theft Security System.
Wait 1 minute.
Disarm the Vehicle Theft System.
With the DRBIII
t, read DTC’s.
Does the DRBIII
t display the same DTC?

wiring and connectors for an intermittent condition.
Perform BODY VERIFICATION TEST - VER 1.
2
With the DRBIII
t, actuate the Siren.
Did the siren sound with the actuation and does the Siren function properly
otherwise?
All
Yes
→ This DTC can be ignored if there are no other complaints with the
operation of the Siren.
Perform BODY VERIFICATION TEST - VER 1.
