**Update** XYZ switch replaced, Battery and Alternator check out fine, over 14 volts under load, all terminal ends cleaned and contact points cleaned and re-seated. Again the Disco shifts fine(gears 1-4) and seems to run great yet the M & S lights are still blinking along with the D on the digital display. The check engine light is ON as is the Traction/Hill descent. The codes are as follows:

Check Engine light is ON with code: P0122- stored- Throttle/Pedal Position Sensor/Switch A Circuit Low (I just replace the TPS sensor, perhaps the new one is faulty) Bought from Atlantic British was NOT a Bosch sensor.
ABS code: 0202- state- none- PWM Signal Failure From Engine ECU
Transmission code: 12- state- none- CAN Message WFPDK (DKI) Invalid (FFh)

Any hints or points in the right direction for the next step would be great. Thank you all that have helped so far in this, my other post was under another profile Alt3rEgo74.

 

Did you clear any existing codes after you replaced parts? Some of them won't reset on their own.

 

Mollusc, I have an Icarsoft scanner for the Disco and went into each system and cleared the codes. The check engine code clears but the other 2 codes do not clear. It says the function was successful yet the lights remain on.

 

**UPDATE** weirdest thing. So I swapped out the TPS sensor to try and eliminate the CEL..........**BOOM** all lights went off. Crazy? Maybe but I will take it. I have driven it 60 miles so far and no issues or lights! Thank you Jesus. Now to start saving for the next project/repair. lol
