Pinpoint Test R : B1087:83, B1087:86 Or B1087:88: Notes
Refer to Power Door Locks for schematic and connector information.
Refer to Power Windows for schematic and connector information.
Normal Operation and Fault Conditions
The DDM and PDM communicate with the corresponding rear door module (Driver Rear Door Module (DRDM) and Passenger Rear Door module (PRDM)) over a LIN. The window control switch on the driver door also provides information to the DDM over the same LIN. In the event of a failure on a LIN, the power windows, power locks and switch illumination are inoperative in the corresponding rear door. If there is a LIN failure for the DDM, the controls from the driver window control switch are also inoperative.
DDM/ PDM DTC Fault Trigger Conditions

| B1087:86 | LIN Bus "A": Signal Invalid | Sets when the DDM/ PDM receives invalid data over the LIN. |
| B1087:88 | LIN Bus "A": Bus Off | Sets when the DDM/ PDM receives no data over the LIN. An open or short on the LIN can cause this. |
