4x4 not engaging

[Mukundan Nair]

Team, 

Really would require your support here, from today during our morning drive the 4WD warning light lit up while tried shifting to 4H from 4L. It went off after restarting the vehicle, however now if i try shifting from 2WD to 4H the display blinks and goes blank. The 4WD warning is showing up. Not sure even it is shifting. have anyone experienced such issues with your Xterra's. 

Appreciate everyones input on the matter, any checks i can do / solve myself or do i need to take to garage?

 

Thanks in advance

Seems like a dying solenoid or dead.

Remove battery terminals for 15 min so it can eliminate any electrical gone wonky scenario.

If still behave the same after 15 min, you need to show it to mechanic to check solenoid or its connections.

@Mukundan Nair did you install ABS kill switch ? 
regardless I agree with @Gaurav for checking . 
sometimes even washing can cause this if there is contact !

 

cheers

Hi ,

Seems it was a stuck relay, did the self diagnose.  In the engine bay on left side you can find the relay box. It was relays No:7 &9. removed them cleaned and gave a tap. Reinstalled them and the issue is resolved. Not sure though what has caused it in the first place and hoping it wont repeat.

Thanks for the inputs @Gaurav @Mohamed Seidam & ABS kill switch not yet installed, is it really necessary?

Below are steps on how to do the self diagnose  (without a tool) and the flash code chart, might help someone out later..

" If the engine starts when there is something wrong with the 4WD system, the 4WD warning lamp turns ON or
flickers in the combination meter. When the system functions properly, the warning lamp turns ON when the
ignition switch is turned to “ON”, and it turns OFF after engine starts. To locate the cause of a problem, start
the self-diagnosis function. The 4WD warning lamp in the combination meter will indicate the problem area by
flickering according to the self-diagnostic results. Refer to DLN-59, "DTC Index".
Diagnostic Procedure (A/T models)
1. Warm up engine.
2. Turn ignition switch “ON” and “OFF” at least twice, and then turn ignition switch “OFF”.
3. Move A/T selector lever to “P” position.
4. Turn 4WD shift switch to “2WD” position.
5. Turn ignition switch “ON”. (Do not start engine.)
6. 4WD warning lamp should turn ON.
If 4WD warning lamp does not turn ON, refer to DLN-72, "Diagnosis Procedure".
7. Move A/T selector lever to “R” position.
8. Turn 4WD shift switch to “2WD”, “4H” and “2WD” in order.
9. Move A/T selector lever to “P” position.
10. Turn 4WD shift switch to “4H”, “2WD” and “4H” in order.
11. Move A/T selector lever to “N” position.
12. Turn 4WD shift switch to “2WD” position.
13. Move A/T selector lever to “P” position.
14. Read the flickering of 4WD warning lamp.

Well done @Mukundan Nair for finding a working solution and coming back to post a copy here for everyone's future reference.

THIS IS THE TRUE COMMUNITY SPIRIT. 👏

Rather than just sitting and complaining Xterra forum is not informative here as not many BOTHER to come back and contribute with the working solution, once their problem is resolved.

Hi @Mukundan Nair 

Totally agree with Gaurav here and pleased for you that you managed to get this sorted. Was really worried on Friday we would need to let you exit once this problem started showing. Delighted you got to enjoy the rest of the drives.
