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).

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

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.

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.

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

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.

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.

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.

DTC Troubleshooting

Step

Action

Yes

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

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.

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.
