Description for Work Flow
STEP DESCRIPTION
STEP IGet detailed information about the conditions and the environment when the incident/symptom occurred
using the ªDIAGNOSTIC WORKSHEETº as shown on the previous page.
STEP IIBefore confirming the concern, check and write down (print out using CONSULT-II) the malfunction item,
then erase the code. The malfunction item can be used when duplicating the incident at STEP III & IV.
Study the relationship between the cause, specified by malfunction item, and the symptom described by the
customer. (The ªSymptom Matrix Chartº will be useful. Refer to EC-CD-47.)
STEP IIITry to confirm the symptom and under what conditions the incident occurs.
The ªDIAGNOSTIC WORK SHEETº is useful to verify the incident. Connect CONSULT-II to the vehicle in
DATA MONITOR (AUTO TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform INCIDENT SIMULATION TESTS. Refer to GI section.
If the malfunction code is detected, skip STEP IV and perform STEP V.
STEP IVTry to detect the malfunction item by driving in (or performing) the ªDIAGNOSTIC TROUBLE CONFIRMA-
TION PROCEDUREº. Check and read the malfunction item by using CONSULT-II.
During the malfunction item verification, be sure to connect CONSULT-II to the vehicle in DATA MONITOR
(AUTO TRIG) mode and check real time diagnosis results.
If the incident cannot be verified, perform INCIDENT SIMULATION TESTS. Refer to GI section.
In case the ªDIAGNOSTIC TROUBLE CONFIRMATION PROCEDUREº is not available, perform the ªOVER-
ALL FUNCTION CHECKº instead. The malfunction item cannot be displayed by this check, however, this
simplified ªcheckº is an effective alternative.
The ªNGº result of the ªOVERALL FUNCTION CHECKº is the same as the DTC detection.
STEP VTake the appropriate action based on the results of STEP I through IV.
If the malfunction code is indicated, proceed to specific TROUBLE DIAGNOSIS for the malfunction item.
If the normal code is indicated, proceed to the BASIC INSPECTION. Refer to EC-CD-37. Then perform
inspections according to the Symptom Matrix Chart. Refer to EC-CD-47.
STEP VIIdentify where to begin diagnosis based on the relationship study between symptom and possible causes.
Inspect the system for mechanical binding, loose connectors or wiring damage using (tracing) ªHarness Lay-
outsº.
Gently shake the related connectors, components or wiring harness with CONSULT-II set in ªDATA MONI-
TOR (AUTO TRIG)º mode.
Check the voltage of the related ECM terminals or monitor the output data from the related sensors with
CONSULT-II. Refer to EC-CD-52.
The ªDIAGNOSTIC PROCEDUREº in EC section contains a description based on open circuit inspection. A
short circuit inspection is also required for the circuit check in the DIAGNOSTIC PROCEDURE. For details,
refer to GI section (ªCircuit Inspectionº, ªHOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRI-
CAL INCIDENTº).
Repair or replace the malfunctioning parts.
STEP VIIOnce you have repaired the circuit or replaced a component, you need to run the engine in the same condi-
tions and circumstances which resulted in the customer's initial complaint.
Perform the ªDIAGNOSTIC TROUBLE CONFIRMATION PROCEDUREº and confirm the normal code is
detected. If the incident is still detected in the final check, perform STEP VI by using a different method from
the previous one.
Before returning the vehicle to the customer, be sure to erase the unnecessary (already fixed) malfunction
item in ECM.
