DTC Erasure
NOTE: This operation can also be done with the Honda PGM Tester.
1. Connect the SCS service connector to the service check connector (2P) located on the passenger's side of the center
console.
2. Press the brake oedal.
3. Turn the ignition switch ON (ll) while keeping the brake pedal pressed. The ABS indicator goes off after two seconds.
4. After the indicator goes off, release the brake pedal. The indicator comes on after four seconds.
5. After the indicator comes on, press the brake pedal again. The indicator goes off again after four seconds (the brake
oedal is still Dressed.)
6. After the indicator goes off, release the brake pedal again.
7. After four seconds. the indicator blinks twice for 0.3 second and the DTC is erased.
8. Confirm the DTC indication, and check that the DTC was erased.
NOTE: Always maintain these steps. lf you disconnect the SCS service connector and/or fail to operate the brake pedal
according to the indicator indication, the DTC will not be erased.
Conditions for DTC erasure
. The vehicle is stopped.
. The SCS service connector is connected before the ignition switch is turned ON (ll)
. The brake pedal is pressed before the ignition switch is turned ON (ll).
. The SCS service connector remains connected during this procedure.
The DTC erasure stops and the ABS control unit executes the software funqtion it at least one of the following conditions
b satisfied:
. The vehicle is not stopped.
. The SCS service connector is disconnected during this service.
. TheABScontrol unit receives the normal signal (which is for the ABS control unit) from a Honda PGM Tester.
. The brake pedal is not operated according to the indicator indication
. The DTC erasure is finished.
