Dtc C1061: Abs Pump Motor And/Or Motor Driver Circuit - Suzuki Swift Sport 2004 Service & Repair Manual

Step
5 1) Measure voltage between terminals "E03-14" and "E03-
13" with engine running.
±
Is voltage 18 1.0 V or less?

DTC C1061: ABS Pump Motor and/or Motor Driver Circuit

Wiring Diagram
[A]: ABS hydraulic unit / control module connector
(viewed from terminal side)
1. Battery
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 driver (transistor) of the module (does not follow these commands).
DTC Troubleshooting
Step
1 Was "ABS Check" performed?
2 1) Turn Ignition switch to OFF position.
2) Disconnect ABS hydraulic unit / control module
connector.
3) Check for proper connection to ABS hydraulic unit /
control module connector at terminal "E03-1".
4) If OK, then measure voltage between terminal "E03-1" of
module connector and body ground.
Is it 10 – 14 V?
3 Measure resistance between terminal "E03-13" and "E03-
26" of ABS hydraulic unit / control module connector and
body ground.
Is resistance less than 1
