Ok the C1233 - C1234 or your front wheel speed sensors output

B1676 - is Batteyr voltage out of range.


Check these fuses first and also the abs module connector.

Also if you could give me your VIN number I will look up any recalls.


  • Central junction box (CJB) fuse(s): Interior fuse box
    • 15 (5A)
    • 24 (15A)
  • Battery junction box (BJB) maxi-fuse 24 (60A)
  • BJB mini-fuse 14 (25A)

    If they are ok than you will need to run pinpoint test to locate concern.

    I would fix the voltage first.


    All 3 codes could end up with the same results replace the module.
