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.
