Suzuki Grand Vitara JB419. Service manual — part 86
ABS: 4E-12
ABS Warning Lamp Does Not Come ON at Ignition Switch ON
S5JB0B4504008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ABS warning lamp is controlled by ABS (ESP
®) control module through lamp driver module in
combination meter.
If the antilock brake system is in good condition, ABS (ESP
®) control module turns ABS warning lamp ON at the
ignition switch ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS
warning lamp is turned ON continuously by ABS (ESP
®) control module. Also, it is turned ON continuously by lamp
driver module when the connector of ABS (ESP
®) control module is disconnected.

Troubleshooting
Step
Action
Yes
No
1
1) Turn ignition switch to ON position.
Do other warning lamps come ON?
Go to Step 2.
Go to Step 3.
2
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ignition switch to OFF position and check DTC.
Is there DTC U1073?
Go to “DTC U1073:
Control Module
Communication Bus
Off”.
Substitute a known-
good combination meter
and recheck. If ABS
warning lamp remains
OFF, substitute a
known-good ABS
(ESP
®) hydraulic unit /
control module
assembly and recheck.
3
Is Circuit fuse for combination meter in good condition?
Go to Step 4.
Replace fuse and check
for short circuit to
ground.
4
Check CAN communication circuit between combination
meter and ABS hydraulic unit / control module referring to
“DTC U1073: Control Module Communication Bus Off”.
Is CAN communication circuit in good condition?
Go to Step 5.
Repair or replace.
5
1) Remove combination meter with ignition switch turned
OFF.
2) Check for proper connection to “PPL/RED” and “BLK”
wire of combination meter connector.
3) If OK, turn ON ignition switch and measure voltage at
“PPL/RED” wire of combination meter connector and
vehicle body ground.
Is it 10 – 14 V?
Go to Step 6.
Repair power supply
circuit for combination
meter.
6
1) Measure resistance between “BLK” wire of combination
meter connector and vehicle body ground.
Is resistance less than 2
Ω
?
Replace combination
meter.
“BLK” circuit open or
high resistance.

Troubleshooting
Step
Action
Yes
No
1
1) Perform diagnostic trouble code check.
Is there any DTC(s)?
Go applicable DTC
diag. flow.
Go to Step 2.
2
Are main fuses for ABS pump motor and ABS solenoid in
good condition?
Go to Step 3.
Replace fuse and check
circuit for short to

2) Check for proper connection to ABS hydraulic unit /
control module connector at terminals “E03-1” and “E03-
14” (or “E53-1” and “E53-32”).
3) If OK then turn ignition switch to ON position and
measure voltage between each terminal of “E03-1”,
“E03-14” (or “E53-1”, “E53-32”) and vehicle body
ground.
Are they 10 – 14 V?
Go to Step 5.
“WHT/RED” and/or
“WHT/BLU” circuit
open.
5
1) Turn ignition switch to OFF and measure resistance
between each terminal of “E03-13”, “E03-26” (or “E53-
16”, “E53-47”) and vehicle body ground.
Is resistance less than 2
Ω
?
Go to Step 6.
Ground circuit for ABS
(ESP
®) hydraulic unit /
control module open or
high resistance.
6
Check CAN communication circuit between combination
meter and ABS (ESP
®) hydraulic unit / control module
referring to “DTC U1073: Control Module Communication
Bus Off”.
Is CAN communication circuit in good condition?
Substitute a known-
good combination meter
and recheck. If ABS
warning lamp remains
ON, substitute a known-
good ABS (ESP
®)
hydraulic unit / control
module assembly and
recheck.
Repair or replace.
4E-15 ABS:
EBD Warning Lamp (Brake Warning Lamp) Comes ON Steady
S5JB0B4504011
Wiring Diagram
Circuit Description
EBD warning lamp (brake warning lamp) is controlled by parking brake switch, brake fluid level switch and ABS
(ESP
®) hydraulic unit / control module assembly through lamp driver module in combination meter.
EBD warning lamp turns ON when parking brake switch is ON and/or brake fluid level is lower than minimum level.
The information of parking brake switch and brake fluid level are transmitted from BCM to lamp driver module in
combination meter through CAN communication line.
