Rear O2 Sensors

    CDKAT - Cat diagnosis in OBDII-Mode. Set to zero to disable rear cat DTC

If you want to remove your rear O2s entirely, also set these to zero:

    CDHSH - Post cat O2 heater diagnosis
    CDHSHE - Post cat O2 heater amplifier diagnosis
    CDLSH - Post cat O2 sensor diagnosis
    CLAHSH - Error Class: Bank 1 post cat O2 sensor heater
    CLAHSHE - Error Class: Bank 1 post cat O2 sensor heater amplifier
