For a complete wiring diagram, Refer to the Wiring Information Electrical Diagrams.

Theory of Operation

When the PSM receives a command to perform a special function, it looks at all the variable conditions that must be right. If any one of those necessary conditions are not right, it will not perform that function and will report a DTC to explain why it could not.

- When Monitored:
Continuously with ignition on.

- Set Condition:
If the Programmable Special Module (PSM) receives this information from the BCM when it is commanded to perform a function that depends on the Rear Door being unlocked, this code will set.
