Engine Immobilizer System
THEFT DETERRENT / KEYLESS ENTRY: ENGINE IMMOBILISER SYSTEM: DATA LIST / ACTIVE TEST
1. DATA LIST
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
HINT
Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Smart Access / Data List.
(e) According to the display on the Techstream, read the Data List.
Smart Access (Certification ECU (Smart Key ECU Assembly))
HINT
* *1: This indicates that there is a problem with the communication format between the key and certification ECU (smart key ECU assembly). Electric wave interference, key or certification ECU (smart key ECU assembly) malfunctions, the key of another vehicle being used, etc. are possible causes.
* *2: This indicates that the hybrid control system start permission request signal output from the certification ECU (smart key ECU assembly) is being received by the ID code box (immobiliser code ECU).
* *3: This indicates the certification results of the certification codes of the certification ECU (smart key ECU assembly) and ID code box (immobiliser code ECU).
* *4: This indicates the certification results of the certification codes of the transmission control ECU assembly and ID code box (immobiliser code ECU).
When the transmission control ECU assembly receives an unlock request from the certification ECU (smart key ECU assembly), confirmation of the ID code box (immobiliser code ECU) L code is performed. If the L code matches, the transmission control ECU assembly unlocks the gearshift control. Also, if the S code verification result does not match, the gearshift control will not be unlocked.
* *5: The certification ECU (smart key ECU assembly) outputs a gearshift control unlock request for 10 seconds after the power switch is turned on (ACC) or on (IG), or a hybrid control system start operation is performed.
* *6: The certification ECU (smart key ECU assembly) outputs a gearshift control lock request for 10 seconds after the power switch is turned off and any door is opened with park (P) selected.
* *7: This indicates that the ID code box (immobiliser code ECU) is receiving verification information from the power management control ECU. If the power management control ECU can send the information, the display changes to "OK".
2. ACTIVE TEST
HINT
Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Smart Access / Active Test.
(e) According to the display on the Techstream, perform the Active Test.
