1 DI710 w/o Tachometer: w/ Tachometer: F18894 PRECHECK ANTILOCK BRAKE SYSTEM DI8CS03 1. DIAGNOSIS SYSTEM (a) Check the indicator. When the ignition switch is turned, check that the ABS warning light is on for 3 seconds. If the indicator check result is not normal, proceed to troubleshooting of the ABS warning light circuit (see page DI750). Tc (b) In case of not using handheld tester: Check the DTC. (1) Using SST, connect terminals Tc and of the. SST (3) Read the DTC from the ABS warning light on the combination meter. If no code appears, inspect the ABS warning light circuit or diagnostic circuit (see page DI750 or DI753). Normal Code 2 seconds 0.25 seconds 0.25 seconds As an example, the blinking patterns of normal code and codes 11 and 21 are shown on the left. (4) Codes are explained in the code table on page DI716. (5) After completing the check, disconnect terminals Tc and, and turn off the display. If 2 or more malfunctions are indicated at the same time, the lowest numbered DTC will be displayed first. Codes 11 and seconds 0.5 seconds 1.5 seconds 0.5 seconds 4 seconds Code 11 Code 21 R

2 ANTILOCK BRAKE SYSTEM DI711 Handheld Tester D05981 (c) In case of using handheld tester: Check the DTC. (1) Connect the handheld tester to the. (3) Read the DTC by following the prompts on the tester screen. Please refer to the handheld tester operator s manual for further details. (d) In case of not using handheld tester: Clear the DTC. (1) Using SST, connect terminals Tc and of the. SST Tc (3) Clear the DTC stored in the ECU by depressing the brake pedal 8 or more times within 5 seconds. (4) Check that the warning light indicates the normal code. (5) Remove the SST from the terminals of the. SST BR3890 Handheld Tester D05981 (e) In case of using handheld tester: Clear the DTC. (1) Connect the handheld tester to the. (3) Operate the handheld tester to erase the codes. Please refer to the handheld tester operator s manual for further details. Ts 2. SPEED SENSOR SIGNAL CHECK (Test Mode) If the ignition switch is turned from to ACC or LOCK during the test mode, DTC will be erased. (a) In case of not using handheld tester: Check the sensor signal. (1) Turn the ignition switch. (2) Using SST, connect terminals Ts and of the. SST

3 DI712 ANTILOCK BRAKE SYSTEM (3) Start the engine. NOTICE: Be sure to turn the ignition switch on flat place seconds 0.13 seconds Tc BR3904 (4) Check that the ABS warning light blinks. If the ABS warning light does not blink, inspect the ABS warning light circuit and Ts circuit (see page DI750, DI755). (5) Drive the vehicle straight forward. NOTICE: Step the vehicle for 1 second after turning the ignition switch, and then start driving. Drive the vehicle faster than 28 mph (45 km/h) for several seconds and check that the ABS warning light comes off. (6) Stop the vehicle. (7) Using SST, connect terminals Tc and of the. SST (8) Turn the ignition switch. (9) Read the number of blinks of the ABS warning light. See the DTC list shown on the next page. If every sensor is normal, a normal code is output (A cycle of 0.25 seconds and 0.25 seconds is repeated). If 2 or more malfunctions are indicated at the same time, the lowest numbered code will be displayed first. (10) After doing the check, disconnect the SST from terminals Ts, Tc and of the, and turn the ignition switch. Malfunction Code (Example Codes 72 and 76) seconds 2.5 seconds 0.5 seconds 0.5 seconds 0.5 seconds 0.5 seconds 4 seconds Repeat BR

(2) Do step (3), (5) and (6) described and on the previous page. (3) Read the DTC by following the prompts on the tester screen. Please refer to the handheld tester operator s manual for further details.
