B19F0

B19F0 - Right Power Sliding Door Latch Control 1 Circuit High






For a complete wiring diagram, refer to.

• When Monitored: Whenever the right power sliding door is in a latch cinch or release operation.

• Set Condition: When the right power sliding door latch motor cinch/release output is pulled high prior to or during a latch cinch or release operation for over 100ms, this code will set.






Test Step 1 - DTC Present

• With the scan tool, record and erase DTCs.

• Turn the ignition OFF, wait 10 seconds, then turn the ignition ON.

• Operate the right power sliding door several times if possible.

• With the scan tool, check for DTCs.

• If the B210E Battery Voltage HIGH DTC is present, repair that code before proceeding.

Does the scan tool display B19F0 - Right Power Sliding Door Latch Control 1 Circuit High?

Yes

• Go to Test Step 2

No

• Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for an intermittent condition. Operate the right power sliding door several times and check for any binding conditions in the latch assembly.

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

Test Step 2 - Check For Right Cinch/Release Motor Latch Driver Short to the Right Cinch/Release Motor Unlatch Driver






• Turn the ignition OFF.

• Remove the door module assembly.

• Disconnect the right rear door latch C3 (motor) harness connector.

• Disconnect the right rear door module C1 harness connector.

• Measure the resistance between the right cinch/release motor latch driver circuit and the right cinch/release motor unlatch driver circuit in the right rear door module C1 harness connector.

• Wiggle the harness and check for an intermittent short circuit condition.

Is the resistance less than 10k ohms?

Yes

• Repair the right cinch/release motor latch driver circuit for a short to the right cinch/release motor Unlatch driver circuit.

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

No

• Go to Test Step 3

Test Step 3 - Check the Right Cinch/Release Motor Latch Driver Circuit for a Short to Voltage






• Set the door module assembly on the vehicle floor.

• Reconnect the rear door module C1 connector.

• Reconnect the C316 in Line connector that was disconnected during the removal of the door module assembly.

• Turn the ignition ON.

• Measure the voltage between the vehicle body ground and the right cinch/release motor latch driver circuit in the right rear door latch C3 harness connector.

• Wiggle the harness and check for an intermittent short circuit condition.

Is the voltage more than 4.6 volts?

Yes

• Repair the right cinch/release motor latch driver circuit for a short to voltage. If the wiring is all right, replace the 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 Right Cinch/Release Motor Unlatch Driver Circuit for a Short to Voltage






• Measure the voltage between the vehicle ground and the right cinch/release motor Unlatch driver circuit in the right rear door latch C3 harness connector.

• Wiggle the harness and check for an intermittent short circuit condition.

Is the voltage more than 4.6 volts?

Yes

• Repair the right cinch/release motor latch driver circuit for a short to voltage. If the wiring is all right, replace the door module.

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

No

• Replace the rear door latch assembly or door latch motor.

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