DTC C1061: Pump Motor and/or Motor Driver Circuit

Wiring Diagram










DTC Detecting Condition

The ABS (ESP(R)) 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

1.
Was "ABS Check" performed?
YES -
Go to Step 2.
NO -
Go to ABS Check ABS Check.

2. Turn Ignition switch to OFF position.
Disconnect ABS (ESP(R)) control module connector.
Check for proper connection to ABS (ESP(R)) control module connector at terminal "E03-1" (or "E53-32").
If OK, then measure voltage between terminal "E03-1" (or "E53-32") of module connector and body ground.

Is it 10 - 14 V?
YES -
Go to Step 3.
NO -
"WHT/BLU" circuit open.

3.
Measure resistance between terminal "E03-13" and "E03-26" (or "E53-16" and "E53-47") of ABS (ESP(R)) hydraulic unit / control module connector and vehicle body ground.

Is resistance less than 1 ohms?
YES -
Substitute a known-good ABS (ESP(R)) hydraulic unit / control module assembly and recheck.
NO -
Ground circuit for ABS (ESP(R)) control module open or high resistance.
