4E-25 ABS: 

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

S5JB0A4504016

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 driver (transistor) of the module (does not follow these commands).

DTC Troubleshooting

5

1) Measure voltage between terminals “E03-14” and “E03-

13” with engine running.

Is voltage 18 

±

 1.0 V or less?

Poor connection of 
“E03-14” and/or “E03-
13” terminals. If the 
terminals are in good 
condition, substitute a 
known-good ABS 
hydraulic unit / control 
module and recheck.

Check charging system 
referring to “Generator 
Test (Overcharged 
Battery Check) in 
Section 1J”.

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

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?

Go to Step 3.

“WHT/BLU” circuit 
open.

3

Measure resistance between terminal “E03-13” and “E03-
26” of ABS hydraulic unit / control module connector and 
vehicle body ground.

Is resistance less than 1 

Ω

?

Substitute a known-
good ABS hydraulic unit 
/ control module 
assembly and recheck.

Ground circuit for ABS 
hydraulic unit / control 
module open or high 
resistance.

DTC C1063: Solenoid Valve Power Supply Driver Circuit

S5JB0A4504017

Wiring Diagram

DTC Detecting Condition
ABS control module monitors the voltage at the terminal of solenoid circuit constantly with ignition switch turned ON. 
Also, immediately after ignition switch is turned ON, perform initial check as follows.
Switch solenoid valve power supply driver (transistor) in the order of OFF 

→ ON and check if voltage changes to Low 

→ High. If anything faulty is found in the initial check and when the voltage is low with ignition switch turned ON, this 
DTC will be set.

1

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

2

Check battery voltage.

Is it about 11 V or higher?

Go to Step 3.

Check charging system 
referring to “Battery 
Inspection in Section 
1J” and “Generator Test 
(Undercharged Battery 
Check) in Section 1J”.

3

Check main fuse for ABS solenoid and its terminal.

Is it in good condition?

Go to Step 4.

Replace fuse and check 
for short circuit to 
ground.

4

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 at terminal “E03-14”.

4) If OK, then measure voltage between connector terminal 

“E03-14” and body ground.

Is it 10 – 14 V?

Substitute a known-
good ABS hydraulic unit 
/ control module 
assembly and recheck.

“WHT/BLU” circuit 
imperfect short to 
ground.
