Scan Tool Testing and Procedures
DATA LIST / ACTIVE TEST1. DATA LIST
HINT: According to the DATA LIST displayed by the intelligent tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor 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. Warm up the engine.
b. Turn the ignition switch off.
c. Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
d. Turn the ignition switch to the on position.
e. Turn on the tester. Select the item DIAGNOSIS / ENHANCED OBD II DATA LIST.
g. According to the display on the tester, read the DATA LIST.
2. ACTIVE TEST
HINT: Performing the ACTIVE TEST using the intelligent tester allows the relay, VSV, actuator and so on to operate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one method to shorten labor time. It is possible to display the DATA LIST during the ACTIVE TEST
a. Warm up the engine.
b. Turn the ignition switch off.
c. Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
d. Turn the ignition switch to the ON position.
e. Push the ON button of the intelligent tester.
f. Select the item DIAGNOSIS / ENHANCED OBD II ACTIVE TEST.
g. According to the display on tester, perform the ACTIVE TEST.
LINE PRESS UP in the ACTIVE TEST is performed to check the line pressure changes by connecting the SST to the automatic transaxle, which is used in the HYDRAULIC TEST as well.
HINT: The pressure values in ACTIVE TEST and HYDRAULIC TEST are different from each other.
