NOTE
•{: Activated
• X: Deactivated
• *1: If two or more wheel speed sensor are defective, ABS warning lamp, EBD warning lamp and ESP ® warning lamp are lit and all the control functions are deactivated. If one wheel speed sensor is
defective, ABS warning lamp and ESP ® warning lamp are lit and ABS and TCS / stability control are
deactivated.
• *2: ESP ® OFF mode is cancelled and all control functions are activated.
• *3: EBD control function is activated only if po wer supply circuit is little low voltage malfunction.

Scan Tool DataS7RS0B4604024
The parameter data below are values measured with the scan tool when the normally operating vehicle is under the
following conditions. When taking measurements for comparis on by using the scan tool, be sure to check that the
vehicle is under the following conditions.
• Apply parking brake and block wheels.
• Ignition switch ON.
• Turn OFF air conditioning (if equipped).
• Set the wheel in straight-ahead position and hands off steering wheel.
• Turn OFF all electric loads (except ignition).
• Check that there is no DTC.
Scan Tool Data Definition
Battery Volt (V): Battery Voltage is an analog input
signal read by the ESP ® control module. Certain
ESP ® control module functions will be modified if the
battery voltage falls below or rises above
programmed thresholds.
Pump Motor Driver (V): This parameter indicates the
operational condition of the pump motor driver
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed and LR Wheel Speed (km/h, MPH): Wheel speed
is ESP ® control module internal parameter. It is
computed by reference puls es from the wheel speed
sensor. Brake Switch (ON, OFF):
This switch signal informs
the ESP ® control module whether the brake is active
or not.
Master Cyl Press (MPa): Brake fluid pressure from
brake master cylinder.
G Sensor (lateral) (G): Lateral acceleration is
measured by yaw rate / G sensor assembly and
output to ESP ® control module by pulse signal.
Yaw rate sensor (Deg/s): Yaw rate sensor is measured
by yaw rate / G sensor assembly and output to
ESP® control module by pulse signal.
Steering angle Sen ( °): Steering wheel rotation angle
is measured by steering angle sensor and output to
ESP® control module by pulse signal.

Are they in good condition? Go to Step 4.
Repair or replace.
4 Check ECM circuit for stop lamp switch
1) Disconnect connectors from ECM.
2) Check for proper connection to “E23-20” wire of ECM
connector.
3) If connections are OK, check stop lamp switch circuit for
the following.
• Resistance of “GRN/WHT” wire terminal of stop lamp switch between stop lamp switch connector and ECM
connector is less than 1 Ω (continuity check)
• Resistance between “GRN/WHT” wire terminal of stop lamp switch connector and vehicle body ground is
infinity (ground short check)
• Voltage of between “GRN/WHT” wire terminal of stop switch connector and vehicle body ground is 0 V with
ignition switch tuned ON (power short check)
Are they in good condition? Substitute a known-
good ECM and recheck.
If DTC C1016 is still
detected, substitute a
known-good ESP

hydraulic unit / control
module assembly and
recheck. Repair or replace
defective wire.
