Toyota Tacoma (2015-2018) Service Manual / Engine Immobiliser / Engine Immobiliser System(w/o Smart Key System) / Data List / Active Test

DATA LIST / ACTIVE TEST

1. DATA LIST

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.

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.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus: Body Electrical / Immobiliser / Data List.

(e) Read the Data List according to the display on the Techstream.

Malfunctions in the key, transponder key ECU assembly or transponder key coil.
Different Encrypt Code*1	Code status between transponder chip and transponder key ECU assembly / OK or NG	OK: Codes of transponder chip and transponder key ECU assembly match NG: Codes of transponder chip and transponder key ECU assembly do not match	Problems may be caused by the following: A key from a different vehicle is being used. Malfunctions in the key, transponder key ECU assembly or transponder key coil.
Abnormal Status*1	Transponder chip status signal / OK or NG	OK: Transponder chip status signal normal NG: Transponder chip status signal malfunction (malfunction in code computation in key/transponder key ECU assembly)	Problems may be caused by the following: Communication errors due to external electric wave noise (LF). Malfunctions in the key, transponder key ECU assembly or transponder key coil.
Bcc Malfunction*1	Bcc signal status of transponder chip / OK or NG	OK: Bcc signal normal NG: Bcc signal malfunction (malfunction in code computation in key/transponder key ECU assembly)	Problems may be caused by the following: Communication errors due to external electric wave noise (LF). Malfunctions in the key, transponder key ECU assembly or transponder key coil.
Sub Key	Not available / Unreg or Reg	-	-
Master Key	Whether master key ID code matches ID code registered in transponder key ECU assembly / Unreg or Reg	Unreg: ID code of master key does not match ID code registered in transponder key ECU assembly Reg: ID code of master key matches ID code registered in transponder key ECU assembly	-
Transponder S-code	Number of registered sub-keys / min.: 0, max.: 15	Number of registered sub-keys	-
Transponder M-code	Number of registered master keys / min.: 0, max.: 15	Number of registered master keys	-
Reg Code Space Full	Key registration code memory space full / No or Yes	Yes: Cannot register any more key codes No: Possible to register more key codes	-
+B	+B judgment / Normal or Break	Normal: Battery power supply normal Break: Battery power supply malfunctioning	-
Antenna Coil Status	Antenna coil condition / Normal or Fail	Normal: Antenna coil normal Fail: Antenna coil malfunctioning	-
EEPROM Status	EEPROM status / OK or NG	OK: Data OK NG: Data error	-
E/G Start Permission*2	Engine start permission / NG or OK	NG: Engine start not permitted OK: Engine start permitted	-
Immobi ECU Comm Spd	Immobiliser ECU communication speed / Unknown, 50bps, No Res or 200bps	Unknown: ECU communication speed unknown 50bps: ECU communication speed 50 bps No Res: No response regarding ECU communication speed 200bps: ECU communication speed 200 bps	-
The Number of DTCs	Number of DTCs / Min.: 0, Max.: 255	Number of stored DTCs	-

HINT:

*1: This indicates that there is a problem with the communication format between the key and transponder key ECU assembly. Electric wave interference, key or transponder key ECU assembly malfunctions, the key of another vehicle being used, etc. are possible causes.
*2: Refer to the following Data List items of an actual vehicle.

*1: Without depressing the brake pedal (for Automatic Transmission) or clutch pedal (for Manual Transmission), insert the key into the ignition key cylinder and turn the ignition switch to ACC.
*2: Without depressing the brake pedal (for Automatic Transmission) or clutch pedal (for Manual Transmission), turn the ignition switch to ON.
*3: Turn the ignition switch off and remove the key from the ignition key cylinder.

(f) Enter the following menus: Powertrain / Engine or Engine and ECT / Data List.

(g) Read the Data List according to the display on the Techstream.

Engine (for 2GR-FKS)

Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
Immobiliser Fuel Cut	Status of immobiliser fuel cut / ON or OFF	-	-

Engine and ECT (for 2TR-FE)

Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
Immobiliser Fuel Cut	Status of immobiliser fuel cut / ON or OFF	-	-

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 ignition switch to ON.

(d) Enter the following menus: Body Electrical / Immobiliser or Main Body / Active Test.

(e) Perform the Active Test according to the display on the Techstream.
