CAUTION / NOTICE / HINT

HINT

  1. Use the following procedure to troubleshoot the power mirror control system.
  2. *: Use the Techstream.

PROCEDURE

  1. VEHICLE BROUGHT TO WORKSHOP Result Proceed to NEXT Result: 1 NEXT See step 2
  2. 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 for problem analysis: What Vehicle model, system name When Date, time, occurrence frequency Where Road conditions Under what conditions? Driving conditions, weather conditions How did it happen? Problem symptoms Result Proceed to NEXT Result: 1 NEXT See step 3
  3. PRE-CHECK Measure the battery voltage. Standard Voltage 11 to 14 V If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step. Check the fuses and relays. Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc. Result Proceed to NEXT Result: 1 NEXT See step 4
  4. PROBLEM SYMPTOMS TABLE Refer to Problem Symptoms Table. Refer to «PROBLEM SYMPTOMS TABLE [08/2013 - ]»(ref-635721-S21359790562014070300000) Result Result Proceed to Fault is not listed in problem symptoms table A Fault is listed in problem symptoms table B Result: 2 B See step 6 Result: 1 A See step 5
  5. OVERALL ANALYSIS AND TROUBLESHOOTING* Operation Check Refer to «OPERATION CHECK [08/2013 - ]»(ref-635721-S12457594032014070300000) Terminals of ECU Refer to «TERMINALS OF ECU [08/2013 - ]»(ref-635721-S17939459462014070300000) Data List / Active Test Refer to «DATA LIST / ACTIVE TEST [08/2013 - ]»(ref-635721-S21588056902014070300000) Inspection Result Proceed to NEXT Result: 1 NEXT See step 6
