DTC P16C0: PCM CVT Control System Incomplete Update: General Description

A rewriting function of the control program is in the powertrain control module (PCM) and the control program can be rewritten in the field. The program in the CPU is classified into a powertrain control program (re-writable program) and a program for the rewrite function (non-re-writable program), and the program rewrite function only rewrites the powertrain control program.

When the program rewriting process is not normally finished due to an irregular process such as turning off the PCM power during the CVT CPU re-writing process, and the ignition switch is turned on 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.
