Memory Seat Module (MSMD)

B210E-BATTERY VOLTAGE HIGH

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Engine running, during seat operation.

- Set Condition:
This code is set immediately after the Memory Seat Module receives a high charging system voltage message over the CAN B Bus or detects voltage over 16.5 volts on the (A33) Fused B(+) circuit.





1. CHECK ECM/PCM FOR CHARGING SYSTEM DTC
1. With the scan tool, read ECM/PCM DTCs.

Are there any Charging System DTCs set in the ECM/PCM?

Yes

- Perform the Charging System diagnostic procedures. For diesel engine applications, Testing and Inspection. For gasoline engine applications,Testing and Inspection.

No

- Go To 2

2. VERIFY THAT DTC B210E-BATTERY VOLTAGE HIGH IS ACTIVE
1. With the scan tool, record and erase DTCs.
2. Turn the ignition switch to the OFF position then start the engine and let run for one minute.
3. Attempt to operate the driver power seat.
4. With the scan tool, read DTCs.

Does the DTC B210E-BATTERY VOLTAGE HIGH reset?

Yes

- Go To 3

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the POWER SEAT SYSTEM VERIFICATION TEST. Power Seat System Verification Test.

3. CHECK THE VOLTAGE ON THE (A33) FUSED B(+) CIRCUIT




1. Disconnect the Memory Seat Module connector.

NOTE: Check connectors - Clean and repair as necessary.

2. Start the engine and let idle.
3. Measure the voltage on the (A33) Fused B(+) circuit at the Memory Seat Module connector and compare to voltage at the vehicle battery.

Is the voltage at the Memory Seat Module connector the same as measured at the battery?

Yes

- Replace the Memory Seat Module.
- Perform the POWER SEAT SYSTEM VERIFICATION TEST. Power Seat System Verification Test.

No

- Repair the (A33) Fused B(+) circuit as necessary.
- Perform the POWER SEAT SYSTEM VERIFICATION TEST. Power Seat System Verification Test.
