U241E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: DATA LIST / ACTIVE TEST

DATA LIST / ACTIVE TEST

1. READ DATA LIST
HINT: Using an intelligent tester or 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.
NOTE: 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) Warm up the engine.
(b) Turn the ignition switch to OFF.
(c) Connect the intelligent tester or Techstream to the DLC3.
(d) Turn the ignition switch to ON and turn the tester switch ON.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
(2) Techstream - Select: Powertrain / Engine and ECT / Data List.
(f) Follow the instructions on the tester and read the Data List.
(1) Intelligent tester









(2) Techstream










2. PERFORM ACTIVE TEST
HINT: Using an intelligent tester or Techstream to perform Active Tests allows the 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) Warm up the engine.
(b) Turn the ignition switch to OFF.
(c) Connect the intelligent tester or Techstream to the DLC3.
(d) Turn the ignition switch to ON and turn the tester switch ON.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST.
(2) Techstream - Select: Powertrain / Engine and ECT / Active Test.
(f) Follow the instructions on the tester and perform the Active Test.
(1) Intelligent tester





HINT: *: SOLENOID(SLT) in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transaxle, which is used in the HYDRAULIC TEST Hydraulic Test as well. Please note that the pressure values in the Active Test and HYDRAULIC TEST are different.
(2) Techstream





HINT: *: Active the Solenoid (SLT) in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transaxle, which is used in the HYDRAULIC TEST Hydraulic Test as well. Please note that the pressure values in the Active Test and HYDRAULIC TEST are different.
