Left Power Sliding Door Module
B210A - System Voltage Low
For a complete wiring diagram, refer to.
• When Monitored: At all times.
• Set Condition: When the TIPM sends a message to the power sliding door module that the vehicle voltage is below 10.0 volts for over 15 seconds, this code will set.
Test Step 1 - Check Engine DTCs
• The most probable cause for this DTC in this module is that the charging system or battery has failed, causing a low vehicle system voltage.
• Ensure the battery is fully charged and serviceable before proceeding.
• With the scan tool, read engine DTCs
Are there any engine DTCs present?
No
• Go to Test Step 2
Yes
• Refer to symptom list for problems related to engine.
Test Step 2 - Test for an Intermittent Condition
• With the scan tool, record and erase DTCs
• Start the engine and run for two minutes.
• With the scan tool, check for DTCs.
Does the scan tool display B210A - System Voltage Low?
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 Fused B+ Circuit For High Resistance
• Using the scan tool, read the battery voltage of the power sliding door module.
• Using the scan tool, read the battery voltage of the TIPM (Central Gateway).
Is the voltage within 1.0 volt of each module?
Yes
• Replace the power sliding door module.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Go to Test Step 4
Test Step 4 - Check the Left Power Sliding Door Module Harness
• At this time it will be necessary to remove the power sliding door drive unit assembly from the vehicle.
• Turn the ignition OFF.
• Remove the power sliding door drive unit assembly from the vehicle.
• Disconnect the power sliding door module connector.
• Remove the power sliding door module from the track.
• Connect the C383 left body 4 way harness connector.
• Turn the ignition ON.
• Using a 12 volt test lamp, connect one end to the fused B(+) circuit and the other to the ground in the PSDM 6-way connector.
• The test lamp must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
Does the test tight illuminate brightly?
No
• Repair or replace the track harness as necessary. If you have to order a new harness, be sure to specify if it is for the driver or passenger side of the vehicle. the driver side has a jumper wire in the PSDM connector for driver side identification.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Yes
• Replace the power sliding door module.
