Left Front Door Module

B210B - System Voltage High






For a complete wiring diagram, refer to.

• When Monitored: At all times.

• Set Condition: When the TIPM sends a message to the door module that the input voltage of the vehicle is above 16 volts for over 15 seconds, this code will set.






Test Step 1 - Check Engine DTCs

• With the scan tool, read engine DTCs

Are there any battery or charging system 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, record and erase the DTCs.

• Start the engine and run for two minutes.

• With the scan tool, read the DTCs in the door module.

Does the scan tool display B210B - System Voltage High?

Yes

• Go to Test Step 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 Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

Test Step 3 - Check the Door Track Harness Voltage

• Stop the engine.

• Turn the ignition ON.

• Using the scan tool, read and record the battery voltage of the door module.

• Turn the ignition OFF.

• Disconnect the door module C3 connector.

• Turn the ignition ON.

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

Does the measured voltage differ from the scan tool voltage by more than one (1.0) volt?

Yes

• Replace the door module.

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

No

• Compare this voltage reading to direct battery voltage. If the voltage differs by more than one volt, repair the wiring. If not - Test complete.

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