If DTC P1326 is present, first perform the bearing clearance inspection with the Engine Bearing
Clearance Tester device (SST KQ231-2T110QQK). This device checks the rod bearing clearance
by placing air and vacuum into the cylinder block. Measure the bearing clearance and follow the
instructions in this bulletin. Refer to the flow chart found on page 2, then follow the appropriate
procedure as outlined in this bulletin.
A Vehicle Diagnosis Number (VDN) must be created with or without DTC P1326 after scanning
for DTCs, prior to performing PI1802Y/Z. If a VDN is not created, Warranty claim submission
issues WILL occur.
Before conducting the procedure, verify the vehicle is included in the list of affected VINs.

 NOTICE
To ensure complete customer satisfaction, always remember to refer to WebDCS Warranty
Coverage (validation) Inquiry Screen (Service → Warranty Coverage → Warranty Coverage
Inquiry) for a list of any additional campaigns that may need to be performed on the vehicle
before returning it to the customer.
