4E-17 ABS:
Troubleshooting
Serial Data Link Circuit Check
S6JB0B4504011
Step
Action
Yes
No
1
1) Make sure that:
• Parking brake is completely released.
• Brake fluid level is upper than the minimum level.
Are the check results OK?
Go to Step 2.
Release parking brake
completely and/or
replenish brake fluid.
2
1) Turn ignition switch to ON position.
Does “ABS” warning light come on steady?
Perform “ABS Warning
Light Comes ON
Steady” previously
outlined.
Go to Step 3.
3
1) CAN communication circuit between combination meter,
ABS (ESP
®) hydraulic unit / control module and BCM
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 light remains
ON, substitute a known-
good ABS (ESP
®)
hydraulic unit / control
module assembly and
recheck.
Repair or replace.

Inspection
Step
Action
Yes
No
1
1) Turn ignition switch to ON position.
Does ABS warning light come ON?
Go to Step 2.
Go to Step 6.
2
1) Turn ignition switch to OFF position.
Are main fuses for ABS pump motor and ABS solenoid in
good condition?
Go to Step 3.
Replace fuse and check
for short.
3
1) Disconnect ABS (ESP
®) hydraulic unit / control module
connector.
2) Check for proper connection to ABS (ESP
®) hydraulic
unit / control module connector at terminal “E03-7”.
3) If OK then turn ignition switch to ON position and
measure voltage between terminal “E03-7” and vehicle
body ground.
Is it 10 – 14 V?
Go to Step 4.
“GRN/ORN” wire circuit
open.
4
1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS (ESP
® hydraulic
unit / control module connector at terminals “E03-1” and
“E03-14”.
3) If OK then turn ignition switch to ON position and
measure voltage between each terminal of “E03-1”,
“E03-14” and vehicle body ground.
Are they 10 – 14 V?
Go to Step 5.
“WHT/RED” and/or
“WHT/BLU” wire circuit
open.
5
1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS (ESP
®) hydraulic
unit / control module connector at terminals “E03-13”
and “E03-26”.
3) If OK, measure resistance between each terminal of
“E03-13”, “E03-26” and vehicle body ground.
Are resistance less than 2
Ω
?
Go to Step 6.
Ground circuit for ABS
(ESP
®) hydraulic unit /
control module open or
high resistance.
6
1) Check if communication is possible by trying
communication with other controller (ECM, TCM, BCM,
4WD control module or SDM).
Is it possible to communicate with other controller?
Go to Step 7.
Repair open in common
section of serial data
circuit (“PPL/WHT” wire
circuit) used by all
controllers or short to
ground or power circuit
which has occurred
somewhere in serial
data circuit (“PPL/WHT”
wire circuit).
7
1) Turn ignition switch to ON position.
2) Measure voltage between terminal B of data link
connector and vehicle body ground.
Is voltage 10 – 12 V?
Go to step 8.
Terminal B circuit open
or shorted to ground.
8
1) Turn ignition switch to OFF position.
2) Measure resistance between the following terminals;
• Terminal G of data link connector and vehicle body
ground.
• Terminal G1 of data link connector and vehicle body
ground.
Is each resistance 1
Ω
or less?
Go to step 9.
Terminal G and/or G1
circuit open or high
resistance.

4E-19 ABS:
DTC C1015: G Sensor Circuit Failure (Non-ESP
® Model)
S6JB0B4504012
For ESP
® model, go to “DTC C1015 / C1017 / C1023: Longitudinal G Sensor / Lateral G Sensor / Yaw Rate Sensor in
Yaw Rate / G Sensor Assembly Failure in Section 4F”.
Description
If the signal voltage of G sensor while at a stop does not vary of from that while running, this DTC is set.
Therefore, this DTC may be set when a vehicle is lifted up and its wheel(s) is turned. In such case, clear the DTC and
check again.
DTC Troubleshooting
1) Ignition switch OFF.
2) Check for proper connection from harness to control module.
3) If OK, substitute an ABS hydraulic unit/control module assembly with correct part number.
4) Recheck system.
9
1) Turn ignition switch to OFF position.
2) Check proper connection at “E03-5” (“PPL/WHT” wire)
terminal for serial data circuit.
3) If OK, then check resistance between “E03-5” (“PPL/
WHT” wire) terminal and “PPL/WHT” wire terminal (2) for
serial data circuit in DLC (1).
Is resistance 1
Ω
or less?
Substitute a known-
good ABS (ESP
®)
hydraulic unit / control
module and recheck.
Repair high resistance
or open in “PPL/WHT”
wire circuit for anti lock
brake system.
