Suzuki Grand Vitara JB416 / JB420 / JB419. Manual — part 284

4E-28 ABS:

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.

DTC Troubleshooting

Step

Action

Yes

No

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: For Petrol
Engine Model in Section
1J”, “Generator Test
(Undercharged Battery
Check): For Petrol
Engine Model in Section
1J”, “Battery Inspection:
For Diesel Engine
Model in Section 1J”
and “Generator Test
(Undercharged Battery
Check): For Diesel
Engine Model 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 (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.

“WHT/BLU” circuit
imperfect short to
ground.

1

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

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.

DTC Troubleshooting

Step

Action

Yes

No

1

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

2

1) Check connection of connectors of all control modules

communicating by means of CAN.

2) Recheck DTC.

Is DTC U1073 indicated?

Go to Step 3.

Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.

3

1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control modules

communicating by means of CAN.

3) Check CAN communication circuit between control

modules for open, short and high resistance.

Is each CAN communication circuit in good condition?

Go to Step 4.

Repair insulation of
CAN communication
line circuit referring to
“Precaution for CAN
Communication System
in Section 00”.

4

1) Turn ignition switch to OFF position.
2) Connect connectors of disconnected control modules

communicating by means of CAN.

3) Disconnect each connector.

• ECM
• TCM (A/T model)
• BCM
• 4WD control module (if equipped)
• Keyless start control module (if equipped)
• Steering angle sensor (ESP

® model)

4) Recheck DTC.

Is DTC U1073 detected?

Check ABS (ESP

®)

control module power
and ground circuit. If
circuits are OK,
substitute a known-
good ABS (ESP

®)

hydraulic unit / control
module assembly and
recheck.

Check applicable
control module power
and ground circuit. If
circuit is OK, substitute
a known-good
applicable control
module and recheck.
