Hi guys

Does anyone have a picture or any info on jb131 connector is this small 10 pin connector it? I have to check some pins and can't see what ones to check! This was the small one above the jb155 as shown in picture. Thanks for any help trying to complete the steps according to manual as shown in picture as p4 but the p3 step asked for pin 17 which doesn't exist on this connector so I'm stumped if this is even the right one or not

any pics of loctaion or the actual harness would would be much appreciated

 

JB155 is ON the gearbox CASE. It is not an in-line connector.

The electrical guide is your friend. Page 24 in the front matters section shows in-line harness connectors and the FIGURE 4.1 or 4.2 is the gearbox electrical connections that clearly state the pin numbering at the gearbox to be JB155.

Also please give a MY to your request for info. These cars were made over several years and had changes to the electrical guides over the years.

Thanks Bob but am looking for info on jb131 not jb155! Was having trouble with a code I have come up as p0778 as a 2/4 brake duty problem. I've since changed both of the 2-4 brake duty solenoids and still have the problem and it won't clear. Now I am suspecting a it's a wire problem, unless you have any other ideas. I've also pulled out the tcm and opened it up but there is zero sign of water damage.

Thank car seems to be rough idling a tad but cannot figure this problem out.

 

I did think I remember reading jb131 was the connector to the tcm. Is this correct?

 

The JB131 is the TCM connector ON the TCM (16 bit module).
There are no harness connectors between the TCM and the gearbox for the control valves.

Do you have a 16 bit or 32 bit?? What MY is the car??

You need to look at figures 4.1 or 4.2.
All you need to know is on one of those diagrams.
