If no scrappy in Taiwan you must use eBay or something like this.
You can’t read the MCU in this ELV, so you must swap it from broken ELV to working ELV. Don’t try to read, you can erase it and then only dealer can help you with new entire steering barrel because ELV is not sold lonely as spare part.
To disassemble it no need any special tool, only you have to unscrew the two security screw on it. You make a slit and then unscrew with flat screwdriver.

I can't find the 2 security screws on the ELV. I found only one piece of plastic near the connector. I will share a picture of it.

Ok you already removed it from steering, so you already unscrew the security screw.
At this point is very simple open it: you have to remove the metal cover on the connector side.
You have many folded edges that hold cover it in place.
You need to straighten up these and then remove the cover.
Please if my post helps you push thanks button

Thanks, paskuale. Now I removed the cover. I can see the PCB with only 2 screws. Then I unscrew them but seems the PCB is still attached to the ELV case. I didn't dare to pull the PCB out. Any suggestions?

By the way, how did you test the motor is working or not? Simply apply 12v on the terminal?

Hi mate.
After you removed the two screws you can gently push out the pcb. You need to apply some force because motor terminal are pushed on pcb contacts, don’t worry.
To test motor you can apply 12v on motor terminal, but you must remove pcb first! When you test motor pcb and motor must be disconnected!
Let me know!

Thanks, mate. I used a thin wire in the 2 screw holes to pull it out. Now I can see the motor inside the case. There are two terminals on it, so if I apply 12v on it and motor and mechanical parts move, then I can be sure the motor is working properly? Thanks.

Hello mate! In the first picture you can see the two power terminals of ELV motor. Apply 12v on both terminals and you can see the motor will moove (if it works). To make it moove in contrary you can invert 12v on the terminals.
Pay attention when you make this test, be sure that 12v are only on terminals and not on metal box of ELV.
The motor will start rotate at high speed, when it arrive to end point you will hear “ta-ta-ta-ta” and you must remove power.
Let me know!

Hi mate. I applied 12v on the terminal of motor and the motor rotates in one direction. Then I tried the other direction by inverting 12v. At first it won't rotate, then I increased the current limit to 2A and it rotates. Now the motor can rotates in both direction (with 1A current limit). I guess the motor and mechanical part is fine. Looks like I need to find a good used ELV to transplant the MCU.

I think the same my friend !
Search another ELV with identical part number and final letter too, but with most recent production date and swap MCU and you will be fine!

**yunchuli** · 2nd August, 2018, 11:39 AM

Hi mate, thank you for all the details provided. One further question, do I need to assemble and install the steering column back to the car then test if transplanted ELV works? Or simply connect the cable to the ELV's connector and turn the key to see it gives ignition or not? Any risk if not install the steering column back the car before turn on ignition?

**paskuale** · 2nd August, 2018, 01:20 PM

Mate you can just connect ELV to the car cable, no matter if ELV is on steering column or not!
You can test it without steering column too!

Mate, I soldered 2 new relays that I received from vendor in china but no luck. After clearing the fault code and insert the key, the ELV is not moving a bit and the same fault code (00288, 014) appears. I am going to check the fuse box to see if there's any blown fuses. In addition, I am checking the ebay for the good used ELV, however, I can't find any near Taiwan so far. Is there any ways to bypass the ELV and start the car? Otherwise, I need to buy it from overseas and takes so long to get it....
