ABS: 4E-29
DTC C1061 (No. 61): ABS Pump Motor and/or Motor Relay Circuit
S3RH0A4504018
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 (transistor) of the module (does not follow these commands).
DTC Troubleshooting
I3RH0A450020-01
[A]: ABS hydraulic unit / control module connector E15 2. Main fuse box 4. ABS pump motor
1. Battery 3. Pump motor relay (transistor) 5. ABS hydraulic unit / control module assembly
Step Action Yes No
1 Was “ABS Check” performed? Go to Step 2. Go to “ABS Check”.
2 1) Check pump motor referring to “ABS Hydraulic Unit
Operation Check”.
Is it in good condition?
Check terminals “E15-
1”, “E15-13” and “E15-
26” connection. If
connections OK,
substitute a known-
good ABS hydraulic unit
/ control module
assembly and recheck. Go to Step 3.
3 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 “E15-1”.
4) If OK, then measure voltage between terminal “E15-1” of
module connector and body ground.
Is it 10 – 14 V?
Go to Step 4. “WHT/BLU” circuit
open.
4 Measure resistance between terminal “E15-13” and “E15-
26” of ABS hydraulic unit / control module connector and
body ground.
Is resistance less than 1
Ω
?
Substitute a known-
good ABS hydraulic unit
/ control module
assembly and recheck. “BLK” circuit in open or
high resistance.
