DIAGNOSIS AND TESTING
GLIDE FEATURE
If seat isn’t sliding forward properly:
(1) First use the DRB scan tool to check whether
glide feature is enabled or not. Enable glide feature if
disabled, and go to Step 2.
(2) Turn the ignition ON and then back OFF.
Remove the key. If seat glides rearward, reinsert key
and turn to ON position. If seat doesn’t glide for-
ward, go to Step 3, otherwise the problem has been
fixed. If Learn Guard Bands test has been run and
problem persists, then replace MHSMM.
(3) Now run Learn Guard Bands Diagnostic test as
shown in this section, and go through Step 2 again.
SERVICE PROCEDURES

To program the second driver’s position, repeat the
above procedure using memory switch 2. The second
RKE transmitter can be programmed in the fashion.
To recall either of the programmed positions
momentarily press and release either memory selec-
tor switch 1 or 2. If using RKE, just press and

ment is activated whether manually or by memory
