You need to check the power supply to the steering rack, pins 1 and 2 of the main connector of the rack, should be a red and black wire. Also make sire there is 12 volts from pin 3 to ground. Let me know what the outcome is.
Customer: replied 1 year ago.
That 12v is ok
The code we getting is48000f ICM, active steering: rotor position sensor value invalid
DO1994 interface AL (front axle steering status 48.0.2 ): signal invalid
DO2C67 DSD interface ( status ,DSC 47.1.2) signal invalid
D51A53 signal ( actual value of front axle steering angle 57.1.2) invalid transmitter ICM
Please this are all the code we having problems
Help me
Expert:  JayPutelis replied 1 year ago.
You'll need to check the wiring from the steering rack to the central gateway module (located under the dash on the drivers side at the bottom of the a pillar). This is the flexray communication bus and may be your programming issue. These wires need to be checked for continuity and shorts. Pins 1 and 4 at sub connector of steering rack, and pins 34 and 16 at top connector at central gateway module. Colors of wires are pink/blue and green/blue. Let me know how you make out. -JP
Customer: replied 1 year ago.
We did look that wire an the module that is behind the drivers wheel and was all ok
That is the one I should look one more time ?
Expert:  JayPutelis replied 1 year ago.
You need to check the wires from the rack to module inside the car as stated.
Customer: replied 1 year ago.

Is connected An is not cut
