HINT:
Each ECM terminal's standard voltage is shown in the table below.
In the table, first follow the information under ºConditionº. Look under ºSymbols (Terminal No.)º for the termi-
nals to be inspected. The standard voltage between the terminals is shown under ºSpecific Conditionº.
Use the illustration above as a reference for the ECM terminals.

FREEZE FRAME DATA
Freeze frame data records the engine conditions (fuel system,
calculated load, engine coolant temperature, fuel trim, engine
speed, vehicle speed, etc.) when a malfunction is detected.
When troubleshooting, freeze frame data can help determine
if the vehicle was running or stopped, if the engine was warmed
up or not, if the air/fuel ratio was Lean or Rich, and other data
from the time the malfunction occurred.
The hand±held tester records freeze frame data in five different
instances: 1) 3 times before the DTC is set, 2) once when the
DTC is set, and 3) once after the DTC is set. These data can be
used to simulate the vehicle's condition around the time when
the malfunction occurred. The data may help find the cause of
the malfunction, or judge if the DTC is being caused by a tempo-
rary malfunction or not.
DLC3 (Data Link Connector 3)
The vehicle's ECM uses the ISO 15765±4 for communication
protocol. The terminal arrangement of the DLC3 complies with
SAE J1962 and matches the ISO 15765±4 format.
HINT:
Connect the cable of the hand±held tester to the DLC3, turn the
ignition switch ON and attempt to use the hand±held tester. If
the screen displays UNABLE TO CONNECT TO VEHICLE, a
problem exists in the vehicle side or the tester side.
If the communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.
If the communication is still impossible when the tool is con-
nected to another vehicle, the problem is probably in the tool it-
self. Consult the Service Department listed in the tool's instruc-
tion manual.
