ABS hydraulic unit / control module assembly DTC Detecting Condition The ABS (ESP®) control module monitors the voltage at monitor terminal of pump motor circuit constantly with the ignition switch turned ON. It sets this DTC when the voltage at the monitor terminal does not become high / low according to ON/OFF commands to the motor driver (transistor) of the module (does not follow these commands). DTC Troubleshooting Step Action 1 Was "ABS Check" performed?3) Check for proper connection to ABS (ESP®) control module connector at terminal "E03-1" (or "E53-32"). 4) If OK, then measure voltage between terminal "E03-1" (or "E53-32") of module connector and body ground. Measure resistance between terminal "E03-13" and "E03Substitute a known26" (or "E53-16" and "E53-47") of ABS (ESP®) hydraulic unit good ABS (ESP®) / control module connector and vehicle body ground. hydraulic unit / control module assembly and Is resistance less than 1 ?Ground circuit for ABS (ESP®) control module open or high resistance.
