ON malfunction:
TYPICAL MALFUNCTION THRESHOLDS
Either of the following conditions is met: OFF malfunction or ON malfunction
OFF malfunction:
2 detections are necessary per driving cycle:
1st detection; temporary flag ON
2nd detection; pending fault code ON
ON malfunction:
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.
(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.

(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.

FREEZE FRAME DATA
1. FREEZE FRAME DATA
(a) The vehicle (sensor) status, stored during ABS and/
or VSC operation or at the time of an error code
detection, can be displayed by the intelligent tester.
(b) Only one record of freeze frame data is stored and
the freeze frame data generated during ABS and/or
VSC operation are updated whenever the vehicle
status is changed. Also, the number of the ignition
switch is ON after the freeze frame data is stored
can be stored up to 31 and it can be displayed. After
storing the DTC, the freeze frame data is not up-
dated.
HINT:
If the ignition switch "ON" operation exceeds 31
times, "31"appears on the display.
(c) If a malfunction occurs, the freeze frame data is
stored but the ABS actuation data is deleted.
*
1: If no conditions are specifically stated for "Idling",
it means the shift lever is at N or P position, the A/C
switch is OFF and all accessory switches are OFF.
