Programming and Relearning

The toggling of the horn chirp (between enabled and disabled) can be performed with the use of the DRB III(R) scan tool or by the customer.

DRB III(R) PROGRAMMING
When using the DRB III(R) scan tool, select:
1. "Theft Alarm"
2. "VTSS"
3. "Miscellaneous and then the desired function."

CUSTOMER PROGRAMMING
Using a transmitter programmed to the RKE Module, the status of the horn chirp may be toggled by the customer.

NOTE: The RKE Module is responsible for keeping track of the horn chirp status; thus this procedure does not need to be repeated for each transmitter programmed to the system.

1. With the ignition switch in RUN position, press and hold the transmitter Unlock button for a minimum of 4 seconds to a maximum of 10 seconds.
2. While holding the UNLOCK button for 4-10 seconds, press the LOCK button. A chime will be heard to indicate a successful toggle, at which time both buttons may be released.
