PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Inspect the DLC3.
HINT:
The vehicle's ECM uses the ISO 14230 (M±OBD) communica-
tion protocol. The terminal arrangement of DLC3 complies with
ISO 15031±03 and matches the ISO 14230 format.
Tester ConnectionConditionSpecified Condition
7 (Bus + line) ± 5 (Signal ground)During communicationPulse generation
4 (Chassis ground) ± Body groundConstantBelow 1

5 (Signal ground) ± Body groundConstantBelow 1

16 (B+) ± Body groundConstant9 to 14 V
HINT:
If the display shows UNABLE TO CONNECT TO VEHICLE when you have connected the cable of the hand±
held tester to the DLC3, turned the ignition switch ON and used the hand±held tester, there is a problem on
the vehicle side or tester side.

If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the
original vehicle.

If communication is still impossible when the tester is connected to another vehicle, the problem is
probably in the tester itself, so consult the Service Department listed in the tester's manual.
(b) Check the battery voltage.
Battery voltage: 11 to 14 V
If voltage is below 11V, recharge the battery before proceeding.
2. USING HAND±HELD TESTER
(a) Connect the hand±held tester to the DLC3.
(b) Monitor the ECU data by following the prompts on the tes-
ter screen.
HINT:
The hand±held tester has a ºSnapshotº function which records
the monitored data.
Refer to the hand±held tester operator's manual for further de-
tails.

3. DATA LIST
HINT:
According to the DATA LIST displayed by the hand±held tester, you can read the value of the switch, sensor,
actuator, etc. without parts removal. Reading the DATA LIST as the first step of troubleshooting is one way
to shorten the labor time.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST according to the display on the tester.
