control module
Step Action Yes No
1 Was “Electronic Stability Program Check” performed? Go to Step 2. Go to “Electronic
Stability Program
Check: ”.
2 DTC check for ESP
®
1) Connect scan tool to DLC with ignition switch turned

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 C1015, 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
®
hydraulic
unit / control module
assembly and recheck.
Replace yaw rate / G
sensor assembly.
