2 Controls the hydraulic BRAKE pressure of all four wheels during sudden braking andbraking on hazardous road surfaces, preventing the wheels from locking. The ABS provides the following benefits:(1) Enables steering around obstacles with a greater degree of certainty even during panic braking(2) Enables stopping during panic braking while allowing stability and steerability to a minimum, even on case a malfunction occurs, a diagnosis function and fail-safe SYSTEM have been included for DIAGRAM (1)GENERAL58A-5 WIRING DIAGRAM (2)GENERALWIRING DIAGRAM (3)GENERALHYDRAULIC SYSTEM DIAGRAMDIAGRAM58A-8 GENERALABSCM CONNECTORI : INPUTO : OUTPUTF/SF : Fail safeSRI : Service Reminder IndicatorDLC : Data Link ConnectorModulator connector (E57)Relay Box connector (E58)ABS MODULATOR AND ABS RELAY58A-9 ABS MODULATOR AND ABS RELAYCOMPONENTSM odulator mounting bracket17-26(170-260,12-19)TIGHTENING TORQUE.

4 Disconnect the wheel speed sensor connector and SPEED SENSOR 58A-13 INSPECTION1. Connect an ohmmeter between the wheel speed sensor termi-nals and measure the standard : Front : 1275-1495 Rear : 1260-15402. Connect a voltmeter between the wheel speed sensor termi-nals, and measure the voltage by turning the the voltmeter to measure AC standard : AC voltage OF BRAKE SYSTEMBLEEDING OF BRAKE SYSTEMNOTET here are no special bleeding procedure for the ABS SYS-TEM. For bleeding please use the standard rules as describedfor the conventional BRAKE SYSTEM as OF BRAKE the reservoir cap and fill the BRAKE reservoir withbrake not allow BRAKE fluid remain on a painted it off bleeding by pressurized fluid, do not depress thebrake the vinyl tube to the wheel cylinder bleeder screw, andinsert the other end of tube in a half full container of BRAKE pump the BRAKE pedal several depressing the BRAKE pedal fully, loosen the bleederscrewuntil fluid starts to run out.

5 Then close the bleeder the 3 and 4 until there are no more bubbles in the the bleeder plug screw tightening torque ..Front :7-13 Nm (70-130 , 5-10 )Rear :8-20 Nm (80-200 , 6-15 )Repeat the above procedure for each wheel in the sequenceshown in the 58A-15 SYSTEM DIAGNOSIS STEPINDICATOR CHECKWhen the ignition switch is turned on, check that the ABS SRI goesON for 6 the SRI is not illuminated immediately after ignition on, the ABSfail safe relay may be at TOOL CHECK1.
