This diagnostic code is recorded when the "Power Control Converter 2" electronic control module (ECM) is not sending the necessary parameters to the "Advisor ECM" at the proper rate. The update rate for parameters that are generated by the "Power Control Converter 2ECM" is not correct. The communication failure may be due to disconnected connectors or a faulty wiring harness.The following conditions could cause this diagnostic code to be activated:
Software is installed on the "Power Control Converter 2 ECM" that is not correct.
Software is installed on the "Advisor ECM" that is not correct.
Incompatible software may be installed.
The fuse for the "Power Control Converter 2 ECM" may have failed.Test Step 1. CHECK THE "Advisor ECM" AND THE "POWERTRAIN ECM" FOR PROPER SOFTWARE VERSIONS.
