It is critical that T-SB-0012-13 in addition to the Technical Instructions for this LSC are followed. This TSB
outlines all steps necessary to prevent reprogramming failure. Toyota will not provide reimbursement
coverage for reprogramming failures if this TSB is not followed. If you have a reprogramming failure that
requires ECU replacement and the Technical Instructions and TSB were followed correctly, please create a
case with the Technical Assistance Hotline documenting all information related to the failure. If sufficient
reporting is received related to re-flash failure, there will be consideration for reimbursement.
NOTE: There will be a limited inventory of ECUs available in the rare case that a reprogramming failure
occurs.

For general reprogramming procedures, refer to T-SB-0012-13.
