Precautions in Diagnosing Troubles

To ensure that the trouble diagnosis is done accurately and smoothly, observe the following and follow ELECTRONIC STABILITY PROGRAM CHECK .

Scheme 1

1. Diagnostic information stored in ESP® control module memory can be cleared as well as checked by using SUZUKI scan tool. Before using scan tool, read its Operator's (Instruction) Manual carefully to have good understanding as to what functions are available and how to use it.
2. If the vehicles was operated in any of the following ways, ESP® warning light may light momentarily but this does not indicate anything abnormal in ESP®. The vehicle was driven with parking brake pulled. The vehicle was driven with brake dragging. The vehicle was stuck in mud, sand, etc. Wheel spin occurred while driving. Wheel(s) was rotated while the vehicle was jacked up.
3. Be sure to read «PRECAUTION FOR CAN COMMUNICATION SYSTEM»(/suzuki/grand-vitara/ii-2008-2012/remont/oem-general-information/#precautions) before inspection and observe what is written there.
4. Be sure to use the trouble diagnosis procedure as described in «ELECTRONIC STABILITY PROGRAM CHECK»(/suzuki/grand-vitara/ii-2008-2012/remont/anti-locktraction-control/#electronic-stability-program) . Failure to follow it may result in incorrect diagnosis. (Some other diagnosis trouble code may be stored by mistake in the memory of ESP® control module during inspection.)
5. When disconnecting ESP® control module connector (1), pull up lock lever (2) of connector. When connecting, set the connector on ESP® hydraulic unit/control module assembly and pull down the lock lever (2) until it locks.
6. Communication of ECM, TCM (for A/T model), BCM, ESP® (ABS) control module, 4WD control module (if equipped), keyless start control module (if equipped), HVAC control module, SDM (Advanced air bag model), ID controller (if equipped), combination meter and steering angle sensor is established by CAN (Controller Area Network). For more detail of CAN communication, refer to «CAN COMMUNICATION SYSTEM DESCRIPTION»(/suzuki/grand-vitara/ii-2008-2012/remont/communication-devices/#communication-system) . Therefore, be sure to read «PRECAUTIONS FOR INSTALLING MOBILE COMMUNICATION EQUIPMENT»(/suzuki/grand-vitara/ii-2008-2012/remont/oem-general-information/#precautions) before inspection and handling CAN communication line.

Precautions in On-Vehicle Service

When connector is connected to ESP® hydraulic unit/control module assembly, do not disconnect connectors of sensors with ignition switch ON. Otherwise, DTC will be set in ESP® control module.

Precautions in ESP® Hydraulic Unit Operation Check

ESP® hydraulic unit/control module assembly function is checked by correct wheel lock/release condition when brake pressure is pressurized/depressurized using SUZUKI scan tool. The hydraulic unit operation check referring to ESP® HYDRAULIC UNIT OPERATION CHECK should be performed to confirm the correct brake pipe connection in the following cases.

1. ESP® hydraulic unit/control module assembly was replaced.
2. Brake pipe and/or hose were replaced.

Precautions in Sensor Calibration

ESP® control module stores calibration points data of yaw rate/G sensor assembly and master cylinder pressure sensor. Steering angle sensor stores calibration point data of itself.

Traction control system, stability control system, hill descent control (if equipped) and hill hold control (if equipped) use these sets of data.

When the following operation is done, calibration should be performed since the original calibration points are deleted.

SENSOR CALIBRATION REFERENCE CHART

Perform sensor calibration according to SENSOR CALIBRATION OF ESP® COMPONENTS .

Precautions in Speedometer Test or Other Tests

When performing speedometer or a bench test while rotating a tire, ESP® function must be kept at stop. It is possible to stop ESP® function temporarily by ESP® OFF switch. In this case, however, the function is forced to come back to work when the speed exceeds 30 km/h (18.5 mph) and may hinder accurate testing.

There are two ways to stop the ESP® function completely as described bellow.

1. Connect the SUZUKI scan tool, select to the "ESP® Function Setting" through the "Utility", them select the "Deactivation" to stop the ESP® function. Refer to SUZUKI scan tool operators manual for further details.
2. Disconnect the connector of the steering angle sensor, and ESP® function is forced to enter the failsafe mode, then ESP® function is stopped. However, when this method is used, DTC remains in the memory of the ESP® control module. Therefore, after the test, re-connect the connector, clear DTC in the memory of the ESP® control module. And calibrate steering angle sensor. Refer to «SENSOR CALIBRATION OF ESP® COMPONENTS»(/suzuki/grand-vitara/ii-2008-2012/remont/anti-locktraction-control/#electronic-stability-program__sensor-calibration-of-espr-components) .

Electronic Stability Program (ESP®) has the following main functions.

1. ABS/EBD ABS is that four wheel brake forces are independently varied with referring each wheel slip condition. EBD is that front and rear wheel braking forces are varied with referring loading distribution of the vehicle. ABS improves the vehicle stability, controllability and braking performance. For the details, refer to «ABS DESCRIPTION»(/suzuki/grand-vitara/ii-2008-2012/remont/anti-locktraction-control/#antilock-brake-system-abs__abs-description) .
2. Traction control system Traction control system function is that engine torque is controlled and brake is applied with referring wheel spin condition during vehicle starting and accelerating.
3. Stability control system Stability control system is that engine torque is controlled and brake is applied with referring vehicle condition (over steering, under steering) during cornering.
4. Hill descent control (If equipped) This function controls running of the vehicle on the down-slope stably at a constant low speed without tires being locked. The ESP® control module activates the pump motor and each solenoid valves to operate to increase, retain or reduce the brake pressure applied to 4 wheels. This function enables the vehicle to run on the down-slope with such large gradient where the engine brake alone cannot provide enough deceleration, or where the road surface is rough or slippery, without driver's brake operation.
5. Hill hold control (If equipped) This function prevents occurrence of creeping down which may occur at the driver's foot shift from the brake pedal to the accelerator pedal operation when starting the vehicle parked on the up-slope. The ESP® control module activates each solenoid valve to operate to keep the brake pressure provided by the driver's brake operation. The vehicle can be stopped by this function for no more than 2 seconds. NOTE: ESP is a registered trademark of Daimler AG.
