DTC C1061 (No.61): ABS Pump Motor Circuit

Wiring Diagram










DTC Detecting Condition

The ABS 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 relay of the module (does not follow these commands).

DTC Troubleshooting

1. Check pump motor referring to ABS Hydraulic Unit Operation Check.

Is it in good condition?
YES
Check terminals "E15-25" and "E15-23" connection. If connections OK, substitute a known-good ABS hydraulic unit/control module assembly and recheck.
NO
Go to Step 2.

2. Ignition switch OFF.
Disconnect ABS hydraulic unit/control module connector.
Check for proper connection to ABS hydraulic unit/control module connector at terminal "E15-23".
If OK, then measure voltage between terminal "E15-23" 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 "E15-22" or "E15-24" of ABS hydraulic unit/control module connector and body ground.

Is it infinite (infinity)?
YES
"BLK" circuit open.
NO
Substitute a known-good ABS hydraulic unit/control module assembly and recheck.
