Be sure wait of 10 seconds after ignition switch OFF or ON.
>>
GO TO 5.
IDENTIFY ERROR-DETECTED SYSTEM BY SYMPTOM DIAGNOSIS
Estimate error-detected system based on symptom diagnosis and perform inspection.
Can the error-detected system be identified?
YES>>GO TO 6.
NO>>Check harness and connectors based on the information obtained by interview. Refer to Intermittent Incident.
FINAL CHECK
With CONSULT
-
Check the reference value for “ABS”. Refer to Reference Value.
