ENGINE REPLACEMENT INSTRUCTIONS
FOR DTC P1326 (SC218YZ)

SUBJECT:

This bulletin provides information related to the Technical Service Bulletin previously published (SC218) titled
“Engine Inspection/Replacement and KSDS S/W Installation”. Specifically, this bulletin provides instructions on
which procedures to follow if, after installation of the KSDS, any one of the subject vehicles return to the dealer
with Diagnostic Trouble Code (DTC) P1326 (Knock Signal Range/Performance).
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 pages 2-4, then follow the appropriate procedure as outlined in this bulletin.
Before conducting the procedure, verify the vehicle is included in the list of affected VINs.
Note: TSB SC218 must be completed prior to addressing any concerns associated with DTC P1326, under
SC218YZ.

 IMPORTANT
A Vehicle Diagnosis Number (VDN) must be created with or without DTC P1326, after scanning for
DTCs, prior to performing SC218YZ. If a VDN is not created, Warranty claim submission issues WILL
occur.

 NOTICE
To assure complete customer satisfaction, always remember to refer to KDealer+ 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
