COMPLAINT

After Programming Engine and/or Transmission Control Units, Fault Code 061B Stored in Transmission Control Unit

CAUSE

If you encounter the situation described in the above model vehicles, the cause may be a torque interface issue between the engine and transmission control modules.

REMEDY

To resolve, check for and install newer software for the engine control module using SDS and perform SCN coding of the engine control module as well. Perform quick test and erase fault code.

NOTE: If the fault code 061B reappears, it can be ignored. This is not cause for any parts replacement.

NOTE: If no newer software is available for the engine control module, simply perform the SCN coding of the engine control module.
