Let me check.
Okay, this is a communication network issue between the PCM and the data link connector.
The serial data line is how the modules all communicate with each other. When there is an issue, information does not get there quick enough and the result is what you have.
It is not a generic code at all. It is an important code.
Note
This Pinpoint Test is intended to diagnose the following:
- Standard corporate protocol (SCP) communication bus harness circuits: BUS(+), BUS(-), between DLC and PCM
- Data link connector harness circuits: chassis ground, power ground (PWR GND), battery positive voltage (B+)
- Open VPWR to Powertrain control module (PCM) (12A650)
- Powertrain control module (PCM) (12A650)
Note:Concerns found that affect the entire network are referred to in the Module Communication Network, Information Bus.
Pinpoint Test Schematics and Connectors
You are going to need someone with an advanced scan tool check this and have them test the serial data lines to see if there is corrosion somewhere causing this issue.
