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.
NOTICE:
In the table below, the value listed under "Normal Condition" are reference values. Do not depend
solely on these reference values when deciding whether apart is faulty or not.
1. READ DATA LIST
(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 / DATA LIST".
(g) According to the display on the tester, read the "DATA LIST".
HINT:
When DTC P0712 is output and OBD II scan tool or intelligent tester output is 150
C (302F),
there is a short circuit.
When DTC P0713 is output and OBD II scan tool or intelligent tester output is -40
C (-40F),
there is an open circuit.
