On
the 2009-2010 Escalade, Escalade EXT, Escalade ESV, Avalanche, Suburban,
Silverado, Tahoe, Sierra, Yukon, Yukon Denali, Yukon XL, and Yukon Denali XL,
the Passenger Presence System (PPS) re-zero procedure is not required.
TIP: 2009-2010 Tahoe
Hybrid and Yukon Hybrid only (NOT Denali or XL Models) are the only full-size
truck models that require the re-zero procedure.
Starting
in 2009 on the full-size pickup and utility models, the PPS features a new
design that does not require it to be re-zeroed using the Tech 2. The re-zero
procedure updated the empty seat reference values stored in the ECU. The re-zero
procedure has been removed from the Tech 2 menu for these models that do not
require a re-zero. Service Information is being updated.
The
Tech 2 looks at the GM part number in the PPS Module and determines if a re-zero
process is needed. If a re-zero is needed, then the option will be available on
the Tech 2 menu. If no re-zero function is listed, it's not necessary to perform
the re-zero procedure.
