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. If the vehicle’s engine is already seized or severely knocking, dealers
are to obtain a techline Prior Warranty Authorization (PWA) to replace the engine.
A Vehicle Diagnosis Number (VDN) must be created with DTC P1326, prior to performing
PI1803Y. 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.
