INSPECTION PROCEDURE
HINT:
Using the intelligent tester to perform ACTIVE TEST 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 TEST
early in troubleshooting is one way to save diagnostic time. DATA LIST information can be displayed while
performing ACTIVE TEST.
1. PERFORM ACTIVE TEST
(a) Warm up the engine.
(b) Turn the ignition switch off.

1. PERFORM 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) Turn on the tester.
(f) Select the item "DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / SHIFT".
(g) According to the display on the tester, perform the "ACTIVE TEST".
HINT:
While driving, the shift position can be forcibly changed with the intelligent tester.
Comparing the shift position commanded by the ACTIVE TEST with the actual shift position enables you
to confirm the problem (See page AX-30).
HINT:
• This test can be conducted when the vehicle speed is 50 km/h (31 mph) or less.
• The shift position commanded by the ECM is shown in the DATA LIST/SHIFT display on the intelligent
tester.
(a) Connect the intelligent tester together with the CAN VIM
(controller area network vehicle interface module) to the
DLC3.
(b) Turn the ignition switch to the ON position and turn the
OBD II scan tool or the intelligent tester main switch ON.
(c) When you use intelligent tester:
Select the item "DIAGNOSIS / ENHANCED OBD II /
DTC INFO / CURRENT CODES".
(d) Read the DTCs using the OBD II scan tool or the
intelligent tester.

INSPECTION PROCEDURE
HINT:
Using the intelligent tester 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.
1. READ DATA LIST

(b) Turn the ignition switch off.
(c) Connect the intelligent tester together with the CAN VIM (controller area network vehicle
