Wiring Diagram
DTC Detecting Condition
The ABS control module monitors the voltage at the terminal of each sensor while the ignition swit ch is ON. When the
voltage is not within the specified range, an applicable DTC will be set. Also, when no sensor signal is inputted at
running, an applicable DTC will be set.
NOTE
When the vehicle was operated in any of the following ways, one of these DTCs may be set even when
the sensor is in good condition. If such possibility is suspected, clear DTC once referring to “DTC
Clearance” and then performing the driving test as described in Step 2 of “ABS Check”, check whether
or not any abnormality exists.
• The vehicle was driven with parking brake pulled.
• Wheel spin occurred while driving.
• Wheel(s) was turned while the vehicle was jacked up.
• The vehicle was stuck.

ESP ® Warning Lamp Does Not Come ON at Ignition Switch ONS7RS0B4604008
Wiring Diagram
Circuit Description
Operation (ON/OFF) of ESP ® warning lamp is controlled by ESP ® control module through lamp driver module in
combination meter.
If ESP ® system is in good condition, ESP ® control module turns ESP ® 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, ESP ® warning lamp is
turned ON continuously by ESP ® control module. Also, it is turned ON continuously by lamp driver module when the
connector of ESP ® control module is disconnected.Inspection Item Referring section

ABS Warning Lamp Does Not Come ON at Ignition Switch ONS7RS0B4604048
Wiring Diagram4
Check ESP ® control module power supply circuit
1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP ® control module
connector at terminals “E85-1” and “E85-32”.
3) If OK, then turn ignition switch to ON position and measure voltage between each terminal of “E85-1”,
“E85-32” and vehicle body ground.
Are they 10 – 14 V? Go to Step 5. “WHT/BLU” and/or
“WHT/RED” circuit
open.
5 Check ESP ® control module ground circuit
1) Turn ignition switch to OFF and measure resistance between each terminal of “E85-16”, “E85-47” and vehicle
body ground.
Is resistance less than 2
Ω? Go to Step 6.
Ground circuit for ESP®
control module open or
high resistance.
6 CAN communication circuit check
1) Check CAN communication circuit between combination
meter and ESP ® 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 warning
lamp remains ON,
substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Repair or replace.

Wiring Diagram 6
Check wheel speed sensor
1) Refer to “Front / Rear Wheel Speed Sensor On-Vehicle
Inspection”, check output voltage or waveform.
Is specified voltage and/or waveform obtained? Substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Replace wheel speed
sensor and recheck.
Step
Action YesNo
DTC Detecting Condition Trouble Area
• Steering angle sensor internal defect is detected by CPU in steering angle sensor.
• Steering angle sensor signal is out of specified range. • Steering angle sensor
• ESP
® control module
Step Action YesNo
1 Was “Electronic Stability Pr ogram Check” performed? Go to Step 2.Go to “Electronic
Stability Program
System Check”.
2 DTC check for ESP®
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ignition switch ON and check DTC for ESP ®.
Are DTC U1073 and/or U1126 detected? Go to applicable DTC
diag. flow.
Go to Step 3.
3 Check sensor calibration
1) Calibrate steering angle sensor referring to “Sensor
Calibration”.
2) Clear all DTC(s) and check DTC for ESP ®.
Is DTC C1024 still detected? Go to Step 4.
Steering angle sensor
calibration was
incompleted.
4 Check steering angle sensor
1) Check steering angle sensor referring to “Steering Angle
Sensor On-Vehicle Inspection”.
Is it good condition? Substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Replace steering angle
sensor.
