Steering Lock System (Diagnostic Codes & Circuit Tests): Other Toyota Corolla X рестайлинг

PROCEDURE

1. REPLACE STEERING LOCK ACTUATOR ASSEMBLY (STEERING LOCK ECU) HINT: The steering lock ECU and steering lock actuator assembly are supplied as a unit. Replace the steering lock actuator assembly. Refer to «DISASSEMBLY»(ref-425883-S41241749182011101200000) . NEXT --> END

1. CHECK VEHICLE CONDITION Check the problem symptom of the steering lock system. Result Condition Proceed to Steering lock cannot be released A Steering cannot be locked B B --> See step 6 A: Go to next step
2. READ VALUE USING TECHSTREAM Turn the engine switch off. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical / Smart Key / Data List. Select the item below in the Data List, and read its value displayed on the Techstream. SMART KEY Tester Display Measurement Item/Range Normal Condition Diagnostic Note Lck/Unlck Rec Steering lock command reception record / YES or NO YES: Steering lock/unlock signal received NO: Steering lock/unlock signal not received - Check if a steering unlock command signal has been received. OK "YES" is displayed on the Techstream display. NG --> See step 8 OK: Go to next step
3. INSPECT STEERING LOCK ACTUATOR ASSEMBLY (STEERING LOCK ECU) Measure the voltage according to the value(s) in the table below. Standard Voltage Tester Connection Condition Specified Condition E39-3 (IGE) - E39-1 (GND) Engine switch off Engine switch on (ACC or IG) Motor activated: Below 1 V Motor not activated: 11 to 14 V NG --> See step 4 OK --> See step 9
4. CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BODY GROUND) Disconnect the E39 connector from the steering lock actuator assembly. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition E39-1 (GND) - Body ground Always Below 1 ohms NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
5. CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - MAIN BODY ECU) Disconnect the E50 connector from the main body ECU. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition E39-3 (IGE) - E50-7 (SLR+) Always Below 1 ohms E39-3 (IGE) - Body ground Always 10 kohms or higher NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK --> REPLACE MAIN BODY ECU
6. INSPECT STEERING LOCK ACTUATOR ASSEMBLY (STEERING LOCK ECU) Measure the voltage according to the value(s) in the table below. Standard Voltage Tester Connection Condition Specified Condition E39-3 (IGE) - E39-1 (GND) The specified condition should be checked after performing the following: Move the shift lever to neutral Turn the engine switch off Open the driver's door Motor activated: Below 1 V Motor not activated: 11 to 14 V NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
7. CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - MAIN BODY ECU) Disconnect the E39 connector from the steering lock actuator assembly. Disconnect the E50 connector from the main body ECU. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition E39-3 (IGE) - E50-7 (SLR+) Always Below 1 ohms E39-3 (IGE) - Body ground Always 10 kohms or higher NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK --> REPLACE MAIN BODY ECU
8. CHECK SMART KEY SYSTEM (for Start Function). Refer to «HOW TO PROCEED WITH TROUBLESHOOTING»(ref-426069-S16159633322011101200000)
9. PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE. Refer to «PROBLEM SYMPTOMS TABLE»(ref-425886-S31999203772011101200000)
