DTC Indication Pattern (When the ABS control unit detected a problem three times.):
Turn the ignition switch ON (II). The ABS indicator light comes on for 2 seconds to check the bulb.
The ABS control unit indicates the DTC 3 times.
If you miscount the blinking frequency or if you recheck the blinking frequency, turn the ignition switch OFF then
turn it ON (II) to cycle the ABS indicator light again.
4. Remove the SCS service connector.
NOTE: The Malfunction Indicator Lamp (MIL) will stay on after the engine is started if the SCS service connector is
connected.
5. Remove the ABS B2 (15 A) fuse in the under-hood fuse/relay box for at least 3 seconds to erase the ABS control unit's
