(a) Check the results obtained in the "SYMPTOM CONFIRMATION AND DTC (AND FREEZE FRAME DATA) CHECK". Then find the output DTC in the DTC chart. Look at the "Trouble Area" column for a list of potentially malfunctioning circuits and / or parts. Go to step NEXT 7 agn 6. PROBLEM SYMPTOMS CHART (a) Check the results obtained in the "SYMPTOM CONFIRMATION AND DTC (AND FREEZE FRAME DATA) CHECK". Then find the problem symptoms in the problem symptoms table. Look at the "Suspected Area" column for a list of potentially malfunctioning circuits and / or parts. NEXT 7. CIRCUIT INSPECTION OR PARTS INSPECTION (a) Confirm the malfunctioning circuits or parts.

CUSTOMER PROBLEM ANALYSIS HINT: In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment.
To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred. Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases. The following 5 items are important points in the problem analysis: What Vehicle model, system name When Date, time, occurrence frequency Where Road conditions Under what conditions? Running conditions, driving conditions, weather conditions How did it happen? Problem symptoms 3. SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE HINT: The diagnostic system in the LAND CRUISER has various functions.
The first function is the Diagnostic Trouble Code (DTC) check. A DTC is a code stored in the ECU memory whenever a malfunction in the signal circuits to the ECU occurs. In a DTC check, a previous malfunction's DTC can be checked by a technician during troubleshooting. cardi NEXT Go to step 7 NEXT END What Vehicle model, system name When Date, time, occurrence frequency Where Road conditions Under what conditions?
