Service Check Signal (SCS) Circuit Method
With the ignition switch OFF, connect the Honda PGM Tester to the 16P Data Link Connector under the driver's side dashboard. Short the SCS circuit-to-body ground using the Honda PGM Tester. Turn the ignition switch ON (II) without pressing the brake pedal.
NOTE:
If you press the brake pedal when turning the ignition switch ON (II), the system shifts to the DTC clearing mode.
The blinking frequency indicates the DTC. DTCs are indicated by a series of long and short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the DTC. See Fig 1 . After determining the DTC, perform appropriate test under DIAGNOSTIC TESTS. See Figure for DTC index.
NOTE:
If the DTC is not memorized, the ABS indicator will go off for 3.5 seconds, and then come back on. If the ABS indicator stays on, trouble shoot for TEST A: BRAKE SYSTEM INDICATOR DOES NOT GO OFF
under SYSTEM TESTS.
The system will not indicate the DTC unless these conditions are met:
- The brake pedal is not pressed.
- The ignition switch is turned ON (II).
- The SCS circuit is shorted to body ground before the ignition switch is turned ON (II).
