DETAILED FLOW
1.INTERVIEW THE CUSTOMER
Clarify customer concerns before inspection. First of all, perform an interview utilizing BRC-53, "
Diagnostic
Work Sheet" and reproduce the symptom as well as fully understand it. Ask customer about his/her concerns
carefully. Check symptoms by driving vehicle with customer, if necessary.
CAUTION:
Customers are not professional. Never guess easily like “maybe the customer means that...,” or “ maybe the customer mentions this symptom”.
>> GO TO 2.
2.CHECK SYMPTOM
Reproduce the symptom that is indicated by the customer, based on the information from the customer
obtained in the interview. Also check that the sy mptom is not caused by fail-safe mode. Refer to BRC-39,
"Fail-safe".
CAUTION:
When the symptom is caused by normal operation, fully inspect each portion and obtain the under-
standing of customer that the sympt om is not caused by a malfunction.
>> GO TO 3.
3.PERFORM THE SELF-DIAGNOSIS
With CONSULT
1. Turn the ignition switch OFF → ON.
CAUTION:
Be sure to wait of 10 seconds after turning ignition switch OFF or ON.
2. Perform “Self Diagnostic Result” of “ABS”.
Is DTC detected?
YES >> Record or print Self Diagnostic Results and Freeze Frame Data (FFD). GO TO 4.
NO >> GO TO 6.
4.RECHECK THE SYMPTOM
With CONSULT
1. Erase “Self Diagnostic Result” of “ABS”.
2. Turn the ignition switch OFF → ON → OFF.
CAUTION:
Be sure to wait of 10 seconds after turning ignition switch OFF or ON.
3. Perform DTC confirmation procedures for the malfunctioning system. NOTE:
If some DTCs are detected at the some time, determine the order for performing the diagnosis based on
BRC-42, "
DTC Inspection Priority Chart".
Is DTC detected?
YES >> GO TO 5.
NO >> Check harness and connectors based on the information obtained in the interview. Refer to GI-42,
"Intermittent Incident".
5.REPAIR OR REPLACE MALFUNCTIONING COMPONENT
1. Repair or replace malfunctioning components.
2. Reconnect component or connector after repairing or replacing.
3. When DTC is detected, erase “Self Diagnostic Result” of “ABS”. CAUTION:

Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2.
2. CHECK DTC
1. Check DTC.
2. Perform the following procedure if DTC is displayed.
- Record DTC and freeze frame data (P rint them out with CONSULT.)
- Erase DTC.
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
3. Check related service bulletins for information.

•
Always use a 12 volt battery as power source.
• Do not attempt to disconnect battery cables while engine is
running.
• Before connecting or disc onnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.
• Before removing parts, turn ig nition switch OFF and then dis-
connect battery ground cable.
• Do not disassemble ECM.
• If a battery cable is disconnected, the memory will return to
the ECM value.
The ECM will now start to self-c ontrol at its initial value. So,
engine operation can vary slight ly in this case. However, this
is not an indication of a malf unction. Do not replace parts
because of a slight variation.
• If the battery is disconnected, the following emission-related
diagnostic information will be lost within 24 hours.
- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
• When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.
• Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and cond enser, thus resulting in dam-
age to ICs.
• Keep engine control system harness at least 10 cm (4 in) away
from adjacent harness, to prevent engine control system mal-
functions due to receiving externa l noise, degraded operation
of ICs, etc.
• Keep engine control system parts and harness dry.
• Before replacing ECM, perform ECM Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-71, "
Reference Value".
• Handle mass air flow sensor carefully to avoid damage.
• Do not clean mass air flow senso r with any type of detergent.
• Do not disassemble electric th rottle control actuator.
• Even a slight leak in the air intake system can cause serious
incidents.
• Do not shock or jar the camsh aft position sensor (PHASE),
crankshaft position sensor (POS).
