Dynamic Stability Control System: Removal & Installation Mazda CX-5 I

DSC HU/CM REMOVAL/INSTALLATION

Note. When the ignition is switched to ON or the engine is started after the DSC HU/CM have been replaced, the DSC CM reads data from the instrument cluster via CAN communication to perform automatic configuration. The DSC HU/CM prior to replacement stores the vehicle specification information. A new DSC HU/CM does not store any vehicle specification information.

Scheme 24

1. Remove the plug hole plate. (See «PLUG HOLE PLATE REMOVAL/INSTALLATION [SKYACTIV-G 2.0]»(ref-615399-S02010689542014051000000) ).
2. Remove the bracket. (See «WASHER TANK REMOVAL/INSTALLATION»(ref-615468-S33892862142014051000000) ).
3. Remove in the order indicated in the table.
4. Install in the reverse order of removal.
5. After installation, add brake fluid, bleed the air, and inspect for fluid leakage. (See «BRAKE FLUID AIR BLEEDING»(ref-615413-S33446886702014051000000) ).
6. Perform the following procedure to implement the DSC HU/CM automatic configuration. Switch the ignition ON (engine off) and wait for 10 s or more. Switch the ignition to off and wait for 3 s or more. Switch the ignition ON (engine off) and wait for 3 s or more. The automatic configuration procedure is completed.

7. Perform the DSC related parts sensor initialization procedure. (See «DSC RELATED PARTS SENSOR INITIALIZATION PROCEDURE»(ref-615419-S01468492602014051000000) ).
8. Perform the tire pressure monitoring system initialization procedure. (See «TIRE PRESSURE MONITORING SYSTEM INITIALIZATION PROCEDURE»(ref-615392-S35717106802014051000000) ).
9. Clear the DTCs from the memory. (See «ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)]»(ref-615393-S38924199552014051000000) ). (Scheme 24): Identifying DSC/HU CM Connector, Brake Pipe, Nut, Bolt And Bracket With Torque Specifications

Scheme 25

1. Pull the lock lever down in the direction of the arrow while pressing the tab of the connector cover.
2. Pull the connector toward the vehicle rear and remove it. (Scheme 25): Removing DSC HU/CM Connector

Scheme 26

1. Place an alignment mark on the brake pipe and DSC HU/CM.
2. Apply protective tape to the connector to prevent brake fluid from entering.
3. Disconnect the brake pipes. (Scheme 26): Identifying Brake Pipe

Scheme 27

1. Align the marks made before removal and install the brake pipe to the DSC HU/CM and brake pipe joint referring to the figure.
2. Tighten the brake pipe to the specified torque using the commercially available flare nut wrench. (Scheme 27): Identifying Primary And Secondary Side Master Cylinder

Scheme 28

1. Connect the connector and pull the lock lever up in the direction of the arrow.
2. After connecting the connector, verify that the connector cover is completely pushed in. (Scheme 28): Pulling Lock Lever

Rear ABS Wheel-speed Sensor Removal Note

1. Pull aside the mudguard and remove the rear ABS wheel-speed sensor.

TCS OFF SWITCH REMOVAL/INSTALLATION

Note. The TCS OFF switch is integrated with the cluster switch. Refer to SWITCH PANEL REMOVAL/INSTALLATION to remove the cluster switch.

1. Remove the cluster switch from the switch panel. (See «SWITCH PANEL REMOVAL/INSTALLATION»(ref-615455-S35661694702014051000000) ).
2. Install in the reverse order of removal.

Scheme 29

1. Remove the TCS OFF switch. (See «TCS OFF SWITCH REMOVAL/INSTALLATION»(ref-615419-S29335080852014051000000) ).
2. Verify that the resistance between the TCS OFF switch terminals B and C is as indicated in the table. If not as indicated in the table, replace the TCS OFF switch. (Scheme 29): TCS OFF Switch - Circuit Diagram TCS OFF SWITCH SPECIFICATION Terminal Test condition Resistance (ohms) B-C Switch pressed 0 Switch released 1139.99-1163.01
3. Apply battery voltage to TCS OFF switch terminal J, and connect terminal I to ground.
4. Verify that the LED illuminates. If there is any malfunction, replace the TCS OFF switch.
