Right Front Door Module

B210D - Battery Voltage Low

For a complete wiring diagram, refer to.

• When Monitored: At all times.

• Set Condition: The module senses voltage input below 9.0 volts for over 15 seconds.






Test Step 1 - Check Engine DTCs

• With the scan tool, read engine DTCs.

Are there any engine charging or battery DTCs present?

Yes

• Perform the appropriate diagnostic procedure.

No

• Go to Test Step 2

Test Step 2 - Test for an Intermittent Condition

• With the scan tool, erase all the DTCs.

• Start the engine and run for 2 minutes.

• With the scan tool, read the DTCs.

Does the scan tool display B210D - Battery Voltage Low?

Yes

• Go to Test Step 3

No

• The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Test Step 3 - Check the Voltage At the Door Module Harness

• Turn the ignition OFF.

• Disconnect the door module C3 Harness connector.

• Turn the ignition ON.

• Using a voltmeter, measure the voltage between the fused B + circuit and the grounds in the door module C3 connector.

• Measure the voltage across the battery terminals.

Is the voltage within one volt of battery voltage?

No

• Repair the fused B + circuit for high resistance.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Yes

• Replace the door module.
