Inspection Procedure

NOTE: When replacing the skid control ECU or brake actuator assembly, perform initialization of linear solenoid valve and calibration (see INITIALIZATION ).

CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU TO BRAKE ACTUATOR ASSEMBLY)

Disconnect the skid control ECU and brake actuator assembly connector.

Measure the resistance according to the value(s) in the table below.

Resistance

TESTER CONNECTION SPECIFIED CONDITION REFERENCE CHART

Tester Connection	Specified Condition
A13-9 (PCK1) - A16-37 (PCK1)	Below 1 Ω
A13-26 (PAC1) - A16-46 (PAC1)	Below 1 Ω
A13-27 (VCM) - A16-35 (VCM)	Below 1 Ω
A13-43 (E) - A16-45 (E)	Below 1 Ω

Measure the resistance according to the value(s) in the table below.

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go to next step

RECONFIRM DTC

Clear the DTC (see DTC CHECK / CLEAR ).
Turn the engine switch on (IG).
Check if the same DTC is recorded (see DTC CHECK / CLEAR ).
HINT:

Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.
