4E-26 ABS:
DTC C1061: Pump Motor and/or Motor Driver Circuit
S5JB0E4504017
Wiring Diagram
DTC Detecting Condition
The ABS (ESP
®) 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).

1
Was “ABS Check” performed?
Go to Step 2.
2
1) Turn Ignition switch to OFF position.
2) Disconnect ABS (ESP
®) control module connector.
3) Check for proper connection to ABS (ESP
®) control
module connector at terminal “E03-1” (or “E53-32”).
4) If OK, then measure voltage between terminal “E03-1”
(or “E53-32”) of module connector and body ground.
Is it 10 – 14 V?
Go to Step 3.

Measure resistance between terminal “E03-13” and “E03-
26” (or “E53-16” and “E53-47”) of ABS (ESP
®) hydraulic unit
/ control module connector and vehicle body ground.
Is resistance less than 1
Ω
?
Substitute a known-
good ABS (ESP
®)
hydraulic unit / control
module assembly and
recheck.

DTC C1063: Solenoid Valve Power Supply Driver Circuit Failure
S5JB0E4504018
Wiring Diagram
DTC Detecting Condition
ABS (ESP
®) 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.
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
in related manual” and
“Generator Test
(Undercharged Battery
Check) in Section 1J in
related manual”.

DTC C1071: ABS (ESP
®) Control Module Internal Defect
S5JB0E4504019
Wiring Diagram
DTC Detecting Condition
This DTC will be set when an internal malfunction is detected in the ABS (ESP
®) control module.
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 (ESP
®) control module connector.
3) Check for proper connection to ABS (ESP
®) control
module at terminal “E03-14” (or “E53-1”).
4) If OK, then measure voltage between connector terminal
“E03-14” (or “E53-1”) and body ground.
Is it 10 – 14 V?
Substitute a known-
good ABS (ESP
®)
hydraulic unit / control
module assembly and
recheck.

1
Was “ABS Check” performed?
Go to Step 2.
2
Clear all DTCs and check DTC.
Is it DTC C1071?
Go to Step 3.
Could be a temporary
malfunction of the ABS
(ESP
®) control module.
3
1) Check for proper connection of ABS (ESP
®) control
module connector.
2) If OK, disconnect ABS (ESP
®) control module connector
and check the following.
• Voltage “E03-1” (or “E53-32”) terminal: 10 – 14 V
• Voltage “E03-14” (or “E53-1”) terminal: 10 – 14 V
• Resistance between “E03-13” (or “E53-16”) and body
ground: Continuity
• Resistance between “E03-26” (or “E53-47”) and body
ground: Continuity
Are the check result as specified?
Replace ABS (ESP
®)
hydraulic unit / control
module assembly.
Repair “WHT/RED”,
“WHT/BLU” and/or
“BLK” circuit and
recheck.
