HINT:

Resistance of each solenoid at 20°C (68°F).

NG: REPLACE BRAKE ACTUATOR

OK: GO TO Next Step

CHECK WIRE HARNESS (SKID CONTROL ECU ASSEMBLY - BRAKE ACTUATOR)
NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: CHECK EACH CONNECTION IF SAME CODE IS STILL OUTPUT AFTER DTC DELETION (IF CONNECTION IS NORMAL, SKID CONTROL ECU MAY BE DEFECTIVE)
