Circuit/System Description
Control modules connected to the serial data circuits monitor the communication during normal vehicle operation. Operating information and commands are exchanged among the control modules. Each module on the serial data circuit maintains a transmit error counter and a receive error counter. The counter values increase with detected errors and decrease with error-free messages.
Conditions for Running the DTC
- Ignition=On - For greater than 3 s
- Serial Data=Enabled
Frequency the DTC runs=Continuously - After the running conditions are met
Conditions for Setting the DTC
Serial Data=Message Counter Incorrect - Control module that has set the DTC
The above condition(s) must occur 5 times.
Actions Taken When the DTC Sets
DTCs listed in the DTC Descriptor Category=Type C DTC
Conditions for Clearing the DTC
DTCs listed in the DTC Descriptor Category=Type C DTC
