Inspection Procedure

NOTE: When replacing the ABS and TRACTION actuator assembly, perform zero point calibration (See CALIBRATION ).

PERFORM ACTIVE TEST BY INTELLIGENT TESTER (SLIP INDICATOR LIGHT)

Select the "SLIP INDI LIGHT" in the ACTIVE TEST and operate the SLIP indicator light by the intelligent tester.

ITEM DIAGNOSTIC NOTE

Item	Vehicle Condition / Test Details	Diagnostic Note
SLIP INDI LIGHT	Turns SLIP indicator light ON / OFF	Observe combination meter

Check that "ON" and "OFF" of the SLIP indicator light are indicated on the combination meter when using the intelligent tester.

OK:

Turn the SLIP indicator light on or off in accordance with the intelligent tester.

NG: Go to step 2

OK: REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
