WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

Ignition ON, clear all SIR and PPS DTCs. Refer to Passenger Presence System Flash Code Procedures (SS) . Rezero the PPS using the Passenger Presence System Preload Test (Base) procedure. Verify DTC 063 does not reset.

If DTC 063 resets, replace the PPS module.
