B2767

DTC B2767

Circuit Description
When the memory recall switches are pressed they send a 12-volt signal to the memory seat module (MSM)/driver position module (DPM). The MSM/DPM then commands the driver seat to move in response to the switch inputs.

DTC Descriptors
This diagnostic procedure supports the following DTCs:

^ DTC B2757 Memory 1 Select Switch Circuit Low
^ DTC B2762 Memory 2 Select Switch Circuit Low
^ DTC B2767 Memory Set Switch Circuit Low
^ DTC B2772 Memory Exit Switch Circuit Low

Conditions for Running the DTC
The MSM/DPM must be powered and cannot have B1327 - Battery Voltage Low as an active DTC for this DTC to set.

Conditions for Setting the DTC
^ If a memory switch continues to be active for 30 seconds after the last motor controlled by MSM/DPM reaches the end of its travel, the switch will be considered shorted and the MSM/DPM will set a switch DTC.
^ If a position sensor DTC is current and the associated switch is active for 30 continuous seconds, the switch will be considered shorted and the MSM/DPM will set a switch DTC.

Action Taken When the DTC Sets
^ Current and history codes are set.
^ All memory recall commands and Class 2 Driver Identifier are ignored.
^ The MSM/DPM will respond to any other switch signal that has not set a DTC.

Conditions for Clearing the DTC
^ The DTC automatically clears when the switch circuit setting the DTC is no longer active.
^ The MSM/DPM will clear the history DTC after 50 fault free ignition cycles.

Diagnostic Aids
The MSM is also known as the DPM for this vehicle.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. Checks the existing state of the memory switch by using the current state of the switch parameter.
10. This step verifies the repair.
