| Subject: | Door Locks Delayed Locking Feature Added with Body Control Module (BCM) Replacement |
| Models: | 2002 Chevrolet TrailBlazer, TrailBlazer EXT |
Customers who have had the body control module (BCM) replaced may notice a change
in how their door locks function.
The delayed locking feature was not available for 2002 models. However, after
replacing the BCM with P/N 15065293, the system will function as designed for
the 2003 model year, which has the delayed locking feature. This feature may be turned
on as the default position when the new BCM is programmed and installed. The delayed
locking feature operates with a chime sound when the customer attempts to lock the
vehicle with the driver's door open. This will occur the first time the door lock
button or remote keyless entry is depressed. The doors will not lock for 5 seconds
after the last door is closed.
Because delayed locking was not available in 2002, there is no explanation of
this feature in the Owner's Manual. When a BCM (P/N 15065293) is replaced in
any of the above vehicles, please provide the customer with a copy of page 2-9 from
a 2003 Owners Manual (SI Document ID #878793).
