Step
6 CAN communication circuit check
1) Disconnect connectors of all control modules
communicating by means of CAN.
Is each CAN communication circuit between disconnected
control modules (other than ESP
opened, shorted or high resistance?
7 DTC check for ESP®
1) Connect connectors of disconnected control modules
communicating by means of CAN.
2) Disconnect each connector.
• ECM
• TCM (for A/T model)
• BCM
• 4WD control module (if equipped)
• Keyless start control module (if equipped)
• Steering angle sensor
• Immobilizer control modules
3) Check DTC for ESP®.
Is DTC U1140 detected?

Hydraulic Unit Operation Check

Refer to "Hydraulic Unit Operation Check in Section 4E".

Sensor Calibration

CAUTION
!
If any DTC(s) other than C1075, C1076, C1077
or C1078 are detected, sensor calibration can
not be completed. Repair the detected DTC
first.
NOTE
Steering angle sensor calibration is needed
when battery, dome fuse or the steering
angle sensor is removed.
This sensor calibration can be done with/
without SUZUKI Scan Tool.
When ESP® control module and/or yaw rate /
G sensor assembly is removed, sensor
calibration is needed with SUZUKI Scan Tool.
