Rear Brake Disc
Disc Runout Inspection
1.Loosen the front wheel nuts slightly, then raise thevehicle, and suppon it on safety stands. Removethe front wheels.
Remove the brake pads (see page 19-24).
Inspect the disc surface for damage and cracks.Clean the disc thoaoughly, and remove a

rust.
Use wheel nuts and suitable plain washers to holdthe disc securely against the hub. then mount a dialindicator as shown. and measure the runout at10 mm (0.4 in) from the outer edge of the disc.
Brake Disc Runout:
Service Limit:0.10 mm {0.00,t in)
5. lf the disc is beyond the service limit, refinish thebrake disc,
Max. Retinishing Limit: 8.0 mm {0.31 in)
NOTE: A new disc should be refinished if its runoutis greater than 0.10 mm (0.004 in).

Disc Thickness and Parallelism
Inspection
1. Loosen the front wheel nuts slightly, then raise thevehicle, and support it on safety stands. Removethe front wh6els.
2. Remove the brake pads (see page j9-24).
3. Using a micrometer. measure disc thickness aterght points, approximately 45" apart and 1o mm{0.4 in) in from the outer edge of the disc. Replacethe brake disc if the smallest measurement is lessthan the max. refinishing limit.
Brake Disc Thickness:
Standard: 8.9 - 9.1 mm (0.350 - 0.358 in)Max. Rsfinishing Limit: 8.0 mm {0.31 in}
Brake Disc Parallelirm: 0.015 mm(0.0006 inl msx.
NOTE; This is the maximum allowable differencebetween the thickness measurements.
4. lf the disc is beyond the service limit for Darallelism.refinish the brake disc.
NOTE; See section 18 for brake disc replacement.

Troubleshooting Precautions
ABS Indicator Light
I The ABS indicator light comes on when the ABS control unit detects a problem in the system. However, even thoughthe system is normal, the ABs indicator light can come on, too, under the following conditions. To determine theactual cause of the problem, question the customer about the problem, taking the following conditions into consider-ation.
. Signal disturbance
. Wheel soin
. Only drive wheels rotate. Battery voltage fluctuates
2. When a problem is detected and the ABS indicator light comes on, the indicator light can stay on untat the ignitionswitch is turned off, or it can automatically go off, depending on the mode.. Lightstayson until the ignition switch isturned off;When the system is inthesvstem down mode.o Light automatically goes off:When the system is in the control inhibition mode.(refer to symptom-to-system chart)3 The ABS indicator light stays on when the system is reactivated without erasing the DTC, but it goes off after startingthe car.
when the wheel sensor system is faulty and the ABS indicator light comes on, the algorithm of the system automaticallyturns off the ABS indicator light after the wheel speed signal returns to the normal speed. while, when the DTC is erased,the CPU is reset and the ABS indicator light goes off when the system check€d out normal by the initial diagnosis.Therefore, test-drive the car after servicing the wheel sensor system, and be sure that the ABS indicator light does notcome on.
4. When the ABS control unit outputs battery voltage to the gauge assembty, the ABS indicator light goes off.
Diagnostic Trouble Code (DTC)
1. The diagnostic trouble code (DTC) is memorized when a problem is detected and the ABS indicator light does not gooff, or when the ABS indicator light comes on.The DTC is not memorized when the ABs indicator right comes on unress the cpU is activated.2. The memory can hold any number of DTCs. However, when the same DTc is detected twice or more, the later one iswritten over the old one.
Therefore. when the same problem is detected repeatedly, it is recorded as one DTC.3. The DTCS are indicated in the order of ascending number, not in the order thev occur.4. The DTCS are memorized in the EEpROM {non-volatile memorv}.Therefore, the memorized DTCS cannot be canceled by disconnecting the battery. perform the specified orocedures toerase.
Solf-diagnosis
1. The self-diagnosis can be classifield into these four categories:' Initial diagnosis; Performed right after the engine sta rts and untiltheABs indicator light goes off.o Except ABS control: Performed when the ABS is not functioning,. During ABS control: Performed when the ABS is functioning.. During warning: Performed when the ABS indicator light is ON.2 The system performs the following controls when a problem is detected by the self-diagnosis:. ABS indicator light ON. Memory of DTC
. Mode change to the "system down mode,, or the "control inhibition mode,,.
