ESP® Control Module
NOTE:
If communication between SUZUKI scan tool and ESP® control module is not possible, perform the following checks:
•Check communication condition between PC and VCI using SUZUKI scan tool function.
•Check DLC power circuit and ground circuit.
•Check DLC cable. If necessary, check DLC cable by substituting a known-good DLC cable.
•Check CAN communication system. (“Control Module Communication Bus Off” is detected in any control module.)
•Check ESP® control module power circuit and ground circuit.
•Check DLC power circuit and ground circuit.
•Check DLC cable. If necessary, check DLC cable by substituting a known-good DLC cable.
•Check CAN communication system. (“Control Module Communication Bus Off” is detected in any control module.)
•Check ESP® control module power circuit and ground circuit.
Scan Tool Data Definition
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 pulses from the wheel speed sensor.
G Sensor (G)
Acceleration and deceleration are measured by yaw rate / G sensor in ESP® control module.
Battery Voltage (V)
Battery voltage is an analog input signal read by ESP® control module. ESP® control module functions may be stopped if battery voltage falls below or rises above programmed thresholds.
Pump Motor Driver (V)
This parameter indicates operational condition of pump motor driver (transistor).
Master Cyl Press (MPa)
This indicates brake fluid pressure from brake master cylinder.
G Sensor (Lateral) (G)
Lateral acceleration is measured by yaw rate / G sensor in ESP® control module.
Yaw Rate Sensor (Deg/s)
Yaw rate is measured by yaw rate / G sensor in ESP® control module.
Engine Speed (rpm)
This parameter indicates engine speed sent from ECM through CAN.
Steering Angle Sensor (°)
Steering wheel rotation angle is measured by steering angle sensor and output to ESP® control module by CAN communication signal.
Hill Hold Control State (ON / OFF)
This informs whether hill hold control is operating or not.
Hill Descent Control SW (ON / OFF)
This parameter indicates the state of hill descent control switch.
Brake Light Relay (ON / OFF)
This parameter indicates the state of brake light relay.
Neutral Position Switch (ON / OFF)
This parameter indicates the state of neutral position switch.
Reverse Gear Switch (Back Up Light Switch, ON/OFF)
This parameter indicates the state of back up light switch.
Clutch Switch (CPP No.2 Switch, ON/OFF)
This parameter indicates the state of CPP No.2 switch.
Brake Switch (ON / OFF)
These switch signals inform ESP® control module whether brake pedal is depressed or not.
Stability Control (ON / OFF)
This parameter informs whether active brake is operating or not when vehicle is oversteering or understeering.
TCS Control (Brake) (ON / OFF)
This informs whether active brake is operating or not when vehicle is accelerating.
TCS Control (Engine) (ON / OFF)
This informs whether engine torque control is operating or not when vehicle is accelerating.
ESP® OFF SW State (ON / OFF)
This indicates state of ESP® OFF switch.
Steering Angle Signal (Neutral / Not N)
This indicates whether steering wheel is in straight ahead position or not as detected by steering angle sensor.
Hill Descent Control (With / Without)
This informs whether vehicle is equipped with hill descent control function or not.
Hill Hold Control (With / Without)
This informs whether vehicle is equipped with hill hold control function or not.
IPC Communication State (normal / abnormal)
This informs whether steering angle sensor is for ESP® or not.
