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 ®.
Is DTC U1073 and/or U1100 detected? Go to applicable diag.
flow.
Go to Step 3.
3 Check stop lamp switch circuit
1) Check stop lamp, stop lamp (brake pedal) switch and
their circuit referring to “Brake Light Symptom Diagnosis
in Section 9B”.
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.

2) Turn ignition switch ON and check DTC for ESP ®.
Are DTC C1034 and/or C1073 detected? Go to applicable DTC
diag. flow.
Go to Step 3.
3 Check sensor calibration
1) Calibrate yaw rate / G sensor assembly referring to
“Sensor Calibration”.
2) Clear all DTCs and check DTC for ESP ®.
Are DTC C1017 and/or C1023 still detected? Go to Step 4. Yaw rate / G sensor
assembly calibration is
incompleted.
4 Check yaw rate / G sensor assembly
1) Check yaw rate / G sensor assembly referring to “Yaw
Rate / G Sensor Assembly On-Vehicle Inspection”.
Is it good condition? Substitute a known-
good ESP

unit / control module
assembly and recheck. Substitute a known-
good yaw rate / G
