DTC P16C0: Powertrain Control Module (PCM) CVT Control System Incomplete Update: General Description

The control program in the powertrain control module (PCM) has a rewriting function that can be done in the field. The programs in the PCM CPU are the powertrain control program (rewritable program) and the update program (non-rewritable program). When the program rewriting process is not finished normally, such as turning off the PCM power during the rewriting process, and then turning the ignition switch to ON (II) again, the CVT CPU starts according to the rewriting function program, and this DTC is sent to the FI CPU via serial communication and stored in the PCM.
