I was just getting ready to send you a message. I pulled the cluster out today and unplugged. Checked pins 6&14 and got a 61. With it plugged in I got a 41. I would have gotten to the cluster yesterday but forgot my torx bit at home. Does that mean anything? I will wait to proceed on the last message you sent to make sure. You’re awesome and thanks for the help!!!

 

With the cluster unplugged you should have gotten 120. The cluster has a 120 ohm resister and the ABS has another 120 ohm resistor. When they are both in the circuit and everything is good it reads 60. Since you have the cluster out then un-plug the ABS module and test across 6 and 14. If you get any reading other than OL then the wires are shorted together and follow what I said in my last message so we can figure out which side it is on.

 

Sounds good. I will test 6&14 with the ABS unplugged this afternoon after I get off work. When it comes to other connections and pins. Are the pin configuration top left to right 1,2,3,4,etc? Want to make sure I check the correct pins when I move to the next area. Thanks again.

 

Okay, I unplugged the ABS with the cluster out and still got a 61. I plugged everything back in and tried to locate the next connection under the hood and I think I got the right one. However I am not sure which pins are 4&5. I tested across several and didn’t really get anything. Here are some pics of the connector I unplugged. Was I on the right one, and if I was do you know the correct pins? I looked all over for numbers on the plug and saw nothing. Thanks again for the help.

 

Ok just to confirm, you had the cluster and the ABS module both disconnected and you still got 61ohms at pins 6 and 14? That almost sounds like it is shorting to the medium speed can bus, but we will get to that in a bit.

Yes that is the correct connector. I have attached to callout of the one you are holding in your, but since you took the locking mech out I am not sure if you have it upside down or not. I have marked up with red the 2 wires that are the can bus on the picture you sent. Yellow with black stripe and yellow with brown stripe. Check those across each other on both sides of that split connector.

 

Yes. With the ABS module under the hood disconnected and the Cluster still out, I got a 61. This is with the middle plug on the A pillar disconnected. I will go back and test the 2 pins (4&5) behind the battery and see what it gives me. I have reconnected everything(abs,cluster,a pillar) except the connector behind the battery that you just described the pins about. I will let you know what that says. We are on about day 3 of rain here, so as soon as it permits I will check it out and let you know. Thanks again.

 

Well another curve ball. I went just a second ago to check the resistance on 4&5 on the connection mentioned above and both sides gave me nothing on 4&5(yellowbrown&yellowblack). I checked multiple times and my meter never moved. I tested my meter by connecting my probes just to make sure and all seemed ok. That indicates an open circuit if I’m thinking right but I have no idea why and why on both sides. Glad you are here because this is over my head. Thanks for the help.

 

4 to 5 on the male side of the connector (that is the pin not the plastic housing) goes through the transmission control module and then back up to the same connector to pins 2 and 3. Please double check your pins that you are testing. Check on the male side from 4 to 2 and 5 to 3. On the female side check from pin 4 to the OBD pin 6 and from pin 2 to the ABS module pin 35. Then check from pin 5 to pin 14 on the OBD and pin 3 to the ABS pin 14. Also check resistance to ground on both 6 and 14 just to eliminate that. Just to satisfy my curiosity too, please reconnect everything, but leave the battery out and test every combo for resistance from pins 6 and 14 to pins 3 and 11 on the OBD. so 6-3, 6-14, 6-11, 3-14, 3-11, 11-14. Give me all these readings and hopefully it points us in the right direction.

 

Ok. I will go back to recheck pins 4&5(maybe I had it upside down) and will also check the rest listed. I may need to add some extension leads to my meter. Not sure if they will reach from the pin behind the battery to the OBD. Would you happen to have the pin configuration for the ABS module? Thanks again.

 

I will get to these as soon as I can. My daughter is flying home from the Air Force today so I may be out of the pocket for a couple days spending time with her. Then again I May drag her out there to help me. 😁. Here is my list and I will get it filled out asap.
