B19F3-RIGHT POWER SLIDING DOOR LATCH CONTROL 2 CIRCUIT LOW - DMRR





For a complete wiring diagram Consult Diagrams/Electrical

- 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 or release output is pulled low prior to or during a latch cinch or release operation for more than 100ms, this code will set.





Diagnostic Test

1. CHECK FOR DTCS
With the scan tool, record DTC's and any power sliding door inhibitors.
Erase the DTCs.
Turn the ignition off, wait 10 seconds, then turn the ignition on.
Attempt to operate the Right Power Sliding Door
With the scan tool, read DTCs.
Does the scan tool display this DTC?

Yes

- Go To 2

No

- Using the wiring diagrams as a guide, inspect the wiring and connectors for an intermittent condition.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

2. BINDING POWER SLIDING DOOR
Examine the power sliding door for proper alignment, worn or binding upper and lower rollers, or a loose/damaged weatherstrip.
Examine the power sliding door track assembly for wear or anything that would cause an obstruction to proper operation.
Manually operate the power sliding door on a known good vehicle and notice the effort needed to open and close for comparison.
Especially notice the effort needed to unlatch and latch the power sliding door.
Open the door and manually close the latch. Open and close the latch manually several times and check for any sticking conditions
Were there any mechanical problems found?

Yes

- Refer to Service information for the related procedure(s).
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

No

- Go To 3

3. REAR DOOR MODULE




Turn the ignition off.
Remove the Right Rear Door Trim Panel.
Disconnect the Right Rear Door Module C1 and C2 connectors.
Turn the ignition on.
Manually open the sliding door part way.
Connect a jumper wire from the (Z909) Ground circuit to the (Q48) Right Cinch/Release Motor Unlatch Driver circuit in the C1 connector.

NOTE: Be careful not to spread the terminals in the connector.

Observe the rear door latch position.
Momentarily connect a jumper wire between the Fused (B+) circuit and the (Q46) Right Cinch/Release Motor Latch Driver circuit in the C1 connector.
Reverse the polarity of the jumper wires several times and observe the rear latch to see if it changes each time the wires are reversed.
Does the rear latch change from Latched to Unlatched each time the wires are reversed?

Yes

- Replace the Right Rear Door Module.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

No

- Go To 4

4. CHECK THE (Q46) RIGHT CINCH/RELEASE MOTOR LATCH DRIVER CIRCUIT FOR A SHORT TO GROUND




Turn the ignition is off.
Reconnect the Rear Door Module C2 connector.
Measure the resistance between the (Z909) Ground and the (Q46) Right Cinch/Release Motor Latch 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 below 10,000.0 ohms?

Yes

- Repair the (Q46) Right Cinch/Release Motor Latch Driver circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

No

- Go To 5

5. CHECK THE (Q48) RIGHT CINCH/RELEASE MOTOR UNLATCH DRIVER CIRCUIT FOR A SHORT TO GROUND




Measure the resistance between the (Z909) Ground and the (Q48) 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 below 10,000.0 ohms?

Yes

- Repair the (Q46) Right Cinch/Release Motor Latch Driver circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

No

- Go To 6

6. CHECK FOR (Q46) RIGHT CINCH/RELEASE MOTOR LATCH DRIVER SHORT TO THE (Q48) RIGHT CINCH/RELEASE MOTOR UNLATCH DRIVER




Remove the Door Module Assembly.
Disconnect the Right Rear Door Latch C3 harness connector.
Measure the resistance between the (Q46) Right Cinch/Release Motor Latch Driver circuit and the (Q48) 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 below 10,000.0 ohms?

Yes

- Repair the (Q46) Right Cinch/Release Motor Latch Driver circuit for a short to the (Q48) Right Cinch/Release Motor Unlatch Driver circuit.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.

No

- Replace the Right Rear Door Latch Assembly.
- Perform BODY VERIFICATION TEST - VER 1. Verification Tests.
