ABS Function Test
USING TEST EQUIPMENT1. Raise the car off the ground and support it with safety stands.
2. Check that there is no brake drag.
3. Turn the ignition switch ON (II) and confirm that the ABS indicator light comes on.
NOTE: If the ABS indicator light does not come on, follow trouble shooting.
Special Tool. ALB Checker.:
4. Attach test equipment.
Honda PGM Tester - Connect the PGM (use PGM guide as reference). Follow the tester's prompts instead of steps 5 through 11 of this procedure.
ALB Checker - With the ignition switch OFF, disconnect the Anti-lock Brake System (ABS) inspection connector (6P) from the connector cover located under the glove box, and connect it to the ALB checker. Continue with steps 5 through 11 of this procedure.
5. Shift the transmission to neutral for manual transmission models, or to position for automatic transmission models.
6. Start the engine and release the parking brake.
ALB Checker Features.:
7. Turn the Mode Selector switch to "1".
8. Push the Start Test switch.
NOTE: The ABS indicator light should not come on while the Test in Progress light is on. If the ABS indicator light comes on, confirm the ABS code and perform the appropriate troubleshooting for the code.
9. Turn the Mode Selector switch to "2".
CAUTION: Do not turn the Mode Selector switch when the Test in Progress light is on. Damage to the ALB checker can result.
10. Depress the brake pedal firmly and push the Start Test switch.
- The ABS indicator light should not come on while the Test in Progress light is on.
- There should be kickback on the brake pedal.
NOTE: The kickback should occur approximately 20 seconds after the Start Test switch is pushed.
- Have the assistant check that the wheel controlled by the ABS can be rotated by hand when there is kickback on the brake pedal. Once kickback is felt, designated wheel should be free to rotate and the ABS light should remain "OFF."
ABS Indicator Light Comes On - Confirm the ABS code and perform the appropriate troubleshooting for the code.
ABS Indicator Light Does Not Come On & Wheel Cannot Be Rotated - Check the connection of the modulator wire harness connectors. If the connections are OK, replace the modulator unit.
- The ABS can be checked with a brake tester, too, by checking the brake torque fluctuation of the wheel controlled by the ABS.
11. Turn the Mode Selector switch to "3", "4" and "5". Perform step 10 for each of the test mode positions.
OPERATION SEQUENCE - Simulated by modes of Anti-lock Brake (ALB) checker.
NOTE: The wheel sensors and sensor wire harness are not checked by the ALB checker.
MODE 1:
Mode 1 - Sends the simulated driving signal 0 mph (0 km/h) to 113mph (180 km/h) to 0 mph (0 km/h) of each wheel to the ABS control unit to check the system under normal driving. There should be no kickback.
MODE 2:
Mode 2 - Sends the driving signal of each wheel, then sends the lock signal of the left-rear wheel to the ABS control unit to check the system under left rear wheel lock. There should be kickback.
MODE 3:
Mode 3 - Sends the driving signal of each wheel, then sends the lock signal of the right-rear wheel to the ABS control unit to check the system under right-rear wheel lock. There should be kickback.
MODE 4:
Mode 4 - Sends the driving signal of each wheel, then sends the lock signal of the left-front wheel to the ABS control unit to check the system under left-front wheel lock. There should be kickback.
MODE 5:
Mode 5 - Sends the driving signal of each wheel, then sends the lock signal of the right-front wheel to the ABS control unit to check the system under right-front wheel lock. There should be kickback.
INSPECTION POINTS
If the ABS Indicator light comes on and the system stops during the inspection, confirm the ABS code and perform the appropriate troubleshooting for the code.
No Kickback In Codes 2 Through 5 - ABS light does not come on, the following items are probable causes:
- Pressure switch stuck "ON."
- Clogged or stuck solenoid outlet valve.
- Modulator wire harness connectors improperly connected.
