Connect the ABS tester to the control unit connector at harness side .using the adaptor. Warning Driving the vehicle while the tester is connected to the ABS control unit is extremely dangerous. The brakes could fail, resulting in death or seri- / -1 ous injury. Disconnect the tester from the ABS control unit before driving the vehicle. Gartner Banana

ANTILOCK BRAKE SYSTEM (ABS) P Inspection of ABS system Check system ground Caution To prevent damage to the terminals, create a probe by wrapping a thin wire around the tester lead before inserting. Check for an open circuit in (B) wire from terminals 1 Dl 1 S, and 2F of the control unit connector and ground. Check antilock warning light 1. Remove the instrument cluster. 2. Connect 12V to terminal 2K (C-Ol), and ground to termi- nal 1 K ((2-01). 3. Verify that the ABS warning light illuminates. 4. If there is no illumination, check the meter fuse, bulb, and wiring harness. 5. If OK, check the wiring harness (Warning light - Control unit - Hydraulic unit) and repair or replace as necessary. Check ABS diode 1. Check the meter fuse, bulb, and wiring harness. 2. Check the wiring harness (Warning light - Control unit - Hydraulic unit). 3. Disconnect the hydraulic unit 12-pin connector. 4. Using an ohmmeter, check for continuity of the terminals. 5. If continuity is not as specified, replace the hydraulic unit. Check front and rear valves 1. Disconnect the hydraulic unit 12-pin connector. 2. Using an ohmmeter, check for resistance of the termi- nals. -- 3. If resistance is not as specified, replace the hydraulic unit. 4. If resistance is as spe'cified, check the wiring harness (Hydraulic unit - ABS control unit). E (YIG) - H (B) (Rear Valve) C (BR) - H (B) (Right Front Valve) A (B/W) - H (B) (Left Front Valve) Check brake light switch 1. Disconnect the brake light switch connector. 2. Check for continuity between the terminals of the switch. Resistance (n) Approx. 1 .O-1.2 Approx. 1.0-1.2 Approx. 1 .+I .2 M : Indicates continuity Depressed brake pedal 3. If the continuity is not as specified, check the STOP fuse and wiring harness (Brake light switch - Control unit). 0 I 0 Released brake pedal Gartner Banana
