        Tech Tips


        • When CAN communication system DTCs are output, repair the CAN communication system first.

        • If DTC U0100, U0123, U0124, U0126, U0131 and/or U0142 are among the CAN communication DTCs that are output, first use the Data List to check for a momentary open circuit.

        • If the GTS cannot communicate with the skid control ECU (brake actuator assembly), inspect the CAN communication system.

        • If there is no response from the skid control ECU (brake actuator assembly), inspect the +BS circuit of the skid control ECU (brake actuator assembly).
