Default faults UO121 PO500 on 207

Hi
Peugeot 207 sport 110 1.6 diesel
engine nu JBS10003070

The engine management light came on. Came up on the centre console braking system faulty. Then the fault lights for power steering , ABS and stop light and the Speedometer doesn't work.

I have checkout the faults out using a konnwei and it showed

UO121 lost connection with abs module
PO 500 speed sensor A
P1351 IDM input circuit MF ignition coil control circuit high voltage

I cleared them and re tested the abs fault is still there.

i spotted this on the forma and it looks very similar

https://www.peugeotforums.com/forums/...working-311377


Could this be the way to go I will check the ABS ECU module/pump tomorrow for loose wire connections but thinking it going to be the same as above and refit a ABS ECU module/Pump Which i think is at NS front wheel arch behind plastic housing.

Any more info and help would be gratefully received

Thanks

That number is the main number for the whole unit you may be able to just change the ecu section it has a different number on it though BUT before you do that the power needs to be checked as no power will cause those faults too.

The grease is good leave it there it stops water as you guessed.

How would i go about checking the power. I am trying to find the wiring diagram for the Plug but finding this very difficult to find


So would i just try all the pins for out put in any two or could this do more damage

from what i have read 9/10 it will just be the ecu part, i got the whole pump and just changed the ecu which worked and saved messing with brake fluid etc, but still had the pump on standby.
guess you would just use a multimeter to check for voltage at the plug.

anyway you need the number off the ecu part to match, think some have used other part numbers but i would try to match like for like.
