am currently working on jaguar xj 350 2009 model. the gear box fault light is permanently on and scanner cant see tcm .the fault codes are as follows, pcm - u0101-00, ABS - U0402-00 , PBM - U 0101-00 and ICM - U 2522. I have checked and clean all the earth signal points and have even tested the can signals .

i just want to know where is the tcm located on this model .


thanks House.

 

Mechatronics, part of the valve body inside the gearbox.

 

Make sure that the connector is not full of transmission fluid due to the seal leaking.

 

DE,
Before anything else, check battery voltage AND wheel sensors.
(Look at fault history. If it started with wheel sensor, fix and clear first. Car driven with bad sensor can arrive at this state. TCM is separate module)

 

As Motorcarman said the TCM is inside the transmission.
