B2760

DTC B2760

CIRCUIT DESCRIPTION
The memory select switch signal circuits are supplied 12 volts through a resistor and monitored within the memory seat module (MSM). When a memory select switch is pressed, the signal circuit is closed to ground and the signal circuit voltage is pulled low.

DTC DESCRIPTORs
This diagnostic procedure supports the following DTCs:
- DTC B2755 Memory 1 Select Switch Circuit
- DTC B2760 Memory 2 Select Switch Circuit

CONDITIONS FOR SETTING THE DTC
A memory select switch input to the MSM is active for more than 30 seconds.

ACTION TAKEN WHEN THE DTC SETS
- The MSM will ignore the switch input for which a current status DTC is set.
- When the fault is no longer present a history status DTC will be stored, and switch operation will be restored.

CONDITIONS FOR CLEARING THE DTC
- The DTC will be current for as long as the fault is present.
- When the fault is no longer present the DTC will be a history status code.
- The history DTC will be cleared after 100 error free ignition cycles, or by using the scan tool clearing DTCs feature.

TEST DESCRIPTION

Steps 1 - 9:

The numbers below refer to the step numbers on the diagnostic table.
2. This step verifies that the DTC is current or history by monitoring the switch status for which the code is set.
3. This step tests the memory select switch for an internal fault.
