Suzuki Grand Vitara JB627. Service manual — part 186

4E-25 ABS:

DTC Detecting Condition
The ABS (ESP

®) control module monitors the power source voltage at terminal “E03-14” (or “E53-1”). When the

power source voltage becomes extremely high or low while vehicle is running at more than 20 km/h (13 MPH), this
DTC will be set. As soon as the power source voltage becomes normal, the ABS warning light will be turned off and
the ABS (ESP

®) control module will return to normal operation, but the set DTC will be remain.

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

2

1) Disconnect ABS (ESP

®) hydraulic unit / control module

connector with ignition switch turned OFF.

2) Check for proper connection to ABS (ESP

®) hydraulic

unit / control module connector at terminals “E03-14”
and “E03-13” (or “E53-1” and “E53-16”).

3) If OK, then turn ignition switch to ON position and

measure voltage between terminals “E03-14” and “E03-
13” (or “E53-1” and “E53-16”).

Is voltage 9.7

±

0.3 V or more?

Go to Step 5.

Go to Step 3.

3

1) Turn ignition switch to OFF.
2) Check for proper connection to ABS (ESP

®) hydraulic

unit / control module connector at terminals “E03-13”
and “E03-26” (or “E53-16” and “E53-47”).

3) If OK then turn ignition switch to ON and measure

resistance between each terminal of “E03-13” and “E03-
26” (or “E53-16” and “E53-47”) and vehicle body ground.

Is resistance less than 2

Ω

?

Go to Step 4.

“BLK” wire circuit in
open or high resistance.

4

1) Measure voltage between positive battery terminal and

vehicle body ground with engine running.

Is voltage 9.7

±

0.3 V or more?

Imperfect short between
“WHT/RED” wire circuit
and body ground.

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

5

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

13” (or “E53-1” and “E53-16”) with engine running.

Is voltage 18

±

1.0 V or less?

Poor connection of
“E03-14” and/or “E03-
13” (or “E53-1” and/or
“E53-16”) terminals. If
the terminals are in
good condition,
substitute a known-
good ABS (ESP

®)

hydraulic unit / control
module and recheck.

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

ABS: 4E-26

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

S6JB0B4504016

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).

DTC C1063: Solenoid Valve Power Supply Driver Circuit Failure

S6JB0B4504017

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.

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
