2011 Honda CR-V Rear Hatch Won't Open

Рет қаралды 16,135

Күн бұрын

This 2011 Honda CR-V was brought in to diagnose the rear lift gate or Hatch not opening. The problem turned out to be a broken wire to the left rear door lock knob switch. The wire was broken in the flexible boot between the door and B pillar. This open wire simulated the lock knob switch being in the locked position and caused the MICU to not open the latch. There were no codes related to the condition. The status of the various switches and the output of the MICU to the rear hatch release can be found under Security data.
Jump to 18:40 for the cause of the problem.

Phillip, you are an excellent mechanic, there are not many who would have figured that out. I hope that is not my problem but if so you gave a whole bunch of people great insight! Thank you!

This is so well done. You have the patience of Job. My gate will not lock. I do not have the scanners. I gather this would be next to impossible with out it.

If you can access the latch motor you could test for power and ground a the motor with a test light across the connector. it should light in lock and unlock if not check the wiring at the hinge. you might get lucky.

We just experienced this failure. I’m gonna tell my mechanic so he knows where to look. I did start yelling at the screen when you missed the lock statuses at the beginning, but being in the thick of it without knowing what causes the problem is completely understandable.

Great job!!!!! Definitely a wonky logic. Why would it matter if a door stays locked to allow the hatch to open. 🤦‍♂️

When doors were unlocked, would the driver rear remain physically locked? Trying to troubleshoot without a diagnostic tool. Excellent video! I just paid to have the latch replaced. The intermittent issue quickly returned.

@PhillipBailey 2 ай бұрын

No the door locks worked properly but the wire to the left rear door lock status switch was broken. This caused the door to be reported as locked preventing the rear Hatch from opening. Very stupid logic I'm my opinion. Pop the boots off the door pillars and physically look for broken wires.

I have a CRV that had the lift gate damaged due to an accident. The latch is draining the battery because it’s showing as open. If I cut the purple cable will it stop draining the battery? Thanks

@PhillipBailey Жыл бұрын

If you're referring to the purple wire I fixed in this video then no that won't do it. If the lift gate is showing as open when it's closed it could theoretically cause a battery drain but I'm not 100% certain. Also if I remember correctly the lift gate latch switch is normally closed and opens with the gate open. You could try disconnecting the latch switch and see what happens to the warning message on the dash. If that still shows open the jump the two wires together. Should show closed now. Be sure your on the liftgate latch switch wires.

Thanks for the video, very informative. My wife's 2014 crv rear hatch works ok in warm weather but will not open in cold weather. (Below about 35 degrees) Any ideas??

@PhillipBailey Жыл бұрын

Could be one of the door switches fails based on temperature but could also be wiring. Temperature alters the flexibility of the wires.

@Lu_o3 Жыл бұрын

Same problem here, its common on the 4th gen. Dealer said it freezes in cold weather. I am not paying the 400 for a new one. But you can open it from inside by popping open the little door and pushing the latch to the right with a small screwdriver

Sir am not getting power at purple wire at left rear driver side door.has continuity till micu unit.possible unitnis faulty.

@PhillipBailey Жыл бұрын

How are you testing it for power. You should see 12volts with a volt meter if the switch is open and 0 volts switch closed. If you have continuity on the wire from the micu to the switch check for a short to ground on the circuit. Cut the wire at the minute and see if you have 12volts leaving the micu. Good luck.

So that purple wire was causing the rear hatch door not to open?

@PhillipBailey 2 жыл бұрын

Yes that purple wire is pulled to ground by the internal latch switch when the door is unlocked. If the micu thinks a door is locked it won't allow the operation of the rear Hatch. Could happen with any of the four doors. Stupid logic...

@@PhillipBailey crazy I ordered a new rear hatch Actuator for my 2008 Crv ...replaced it but it does nothing now I'm wondering if something else is causing it....other problems with the crv are the 2 rear door Actuators are going out as well (nasty irritating noise) when unlocking....my ac compressor is not being turned on (something in the relay box) not giving signal from the ground connector to the compressor ...hopefully it's not an expensive fix

That’s the dumbest logic. Honda does some pretty stupid crap. It was looking like the micu at the beginning of the video. Thanks to that tsb

@PhillipBailey 2 жыл бұрын

What adds to the confusion is there are 4 data parameters related to each door that have to do with switches. Lock Knob switch unlocked and locked, latch switch open and closed, lock button on and off. It's so confusing but make sense now. On top of that the data is in several lists...
