Right 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 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 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
