The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
On some early build 2000 DeVilles after replacing the PK3 Module, a technician may encounter DTCs B3031 and B3055. Bulletin 00-02-35-006 references a change to the lock cylinder housing and PK3 Module for a binding key concern, which changes the cylinder housing from plastic to zinc and provides a new PK3 module.
Note: Only Vehicles Built prior to VIN Breakpoint YU315493
Recommendation/Instructions:
If a technician encounters the above two codes B3031-B3055 they need to make sure they also replace the lock cylinder housing from plastic to zinc. If a plastic cylinder housing is on the vehicle the new PK3 module will not communicate with the key causing the above DTCs. Both parts have been released in one kit, P/N 26089463 (Ignition Lock Cylinder Case with Theft Deterrent Module Assembly).
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
