Cell 147: Left Outside Power Mirror
The LH front power window switch receives inputs from the memory function switch EXIT switch through simultaneous memory 1 and memory 2 inputs when you press the EXIT button. The LH front power window switch recognizes the input and sends a message on the simple bus interface (SBI) to the driver door module (DDM).
The message indicates that the LH front power window switch received a memory exit input. The DDM then relays the message through the class 2 serial data line to the Memory Seat Module (MSM).
• | DTC DDM B2242 sets when the EXIT switch is active for 30 seconds continuously. |
• | DTCs B1982 (Battery Voltage High) and B1983 (Battery Voltage Low) must not be current or the diagnostic will not run. |
• | The DDM will not respond to memory EXIT inputs. |
• | The following buttons will not respond because the memory exit button is an input on the memory 1 and memory 2 inputs to the LH front power window switch: |
- | The MEMORY-1 button |
- | The MEMORY-2 button |
• | This DTC will set from current to history when the EXIT input cycles off or when the power mode changes from OFF to RUN. |
• | The history DTC will clear after 50 ignition cycles. |
• | Use a scan tool in order to clear a history DTC. |
A history DTC is evidence of an intermittent condition.
The number(s) below refer to the step number(s) on the diagnostic table.
Clear all DTCs and cycle the ignition in order to test that the DTC did not set falsely.
