Vehicle Speed Signal InspectionBKS001S8
1. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) SELF-DIAGNOSIS
Perform the ABS actuator and electric unit (control unit) self-diagnosis. Refer to BRC-57, "
CONSULT-II Func-
tions" (with VDC system) or BRC-17, "CONSULT-II Functions (ABS)" (without VDC system).
Self
-diagnostic results content
No malfunction detected>>GO TO 2.
Malfunction detected>>Check applicable parts, and repair or replace corresponding parts.
2. CHECK UNIFIED METER AND A/C AMP. OUTPUT SIGNAL

Does it take a long time for the pointer to move to FULL position?
YES >> GO TO 2.
NO >> GO TO 3.
2. QUESTION 2
Was the vehicle fueled with the ignition switch ON?
YES >> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move
to FULL position because of the characteristic of the fuel gauge.
NO >> GO TO 3.28 – 2 : Continuity should exist.
28 – Ground : Continuity should not exist.
