2005 SUZUKI SWIFT Solenoid

Downloaded from www.Manualslib.com manuals search engine 4F-4 Electronic Stability Program:
• Pump motor:The pump motor turns on and applies pressure to each brake when braking is activated in the TCS and stability
control state. When in the pressure reduction mode, it causes the brake fluid in the reservoir to return to the master
cylinder.
• Brake master cylinder pressure sensor: This sensor detects the brake hydraulic pressure in th e primary piping when brake is applied in the normal
condition. Also, it detects the pump motor driving state wh en brake is applied in the TCS and Stability Control state.
• Inlet solenoid valve: In the ABS, TCS and Stability Control stat e, this valve is activated in the pressure keeping and pressure reduction
modes to open the fluid passage, thereby restricting increase of the hydraulic pressure applied to the brake caliper.
• Outlet solenoid valve: In the ABS, TCS and Stability Control state, this valve is activated in the pressure reduction mode to open the fluid
passage, thereby lowering the hydraulic pressure kept in the brake caliper.
• Cut solenoid valve: When brake is applied in the TCS and Stability Control state, this valve is activated to close the fluid passage,
thereby causing the hydraulic pressure generated by the pump motor to apply to the brake caliper.
• Low pressure solenoid valve: When brake is applied in the TCS and Stab ility Control state, this valve is activated to open the fluid passage from
the master cylinder to the pump motor.
Steering angle sensor
The steering angle sensor is assembled with the contact co il as a unit and mounted to the steering column. Detecting
the angle as the steering wheel is turned, it sends that information to the ESP ® control module.

2 Check power supply circuit from battery
1) Check battery voltage.
Is it about 11 V or higher? Go to Step 3.
Check charging system
referring to “Battery
Inspection in Section
1J” and “Generator Test
(Undercharged Battery
Check) in Section 1J”.
3 Check fuse
1) Check main fuse for solenoid and its terminal.
Is it in good condition? Go to Step 4.
Replace fuse and check
for short circuit to
ground.
4 Check solenoid valve power supply circuit
1) Turn ignition switch to OFF position.
2) Disconnect control module connector.
