p/s warning light on the combination meter.
Refer to the chart below for examples of a normal code and dtcs 21 and 22.
Hint:
- If the p/s warning light does not blink to
display any dtcs set or the normal code,
inspect the circuit shown in the table below.
- If two or more malfunctions are detected simultaneously, dtcs will be displayed in ascending numerical order.
- Refer to the diagnostic trouble code chart (see page ps-16) for dtc information.
- Clear dtc

Diagnosis system
Check dlc3
Check the dlc3:
the power steering ecu uses can (iso11898-1)
and iso9141-2 for communication protocol. The
terminal arrangement of the dlc3 complies with
sae j1962 and ...

Freeze frame data
Notice:
It is difficult to show the specified values
(judgment values) clearly because freeze frame
data values change significantly due to

Intake air temperature circuit malfunction
Description
The intake air temperature (iat) sensor, mounted on the mass air flow (maf)
meter, monitors the iat.
The iat sensor has a built-in thermistor with a resistance that varies according
to the temperature of the
intake air. When the iat is low, the resistance of the thermist ...

Diagnostic trouble code chart
If a dtc is displayed during the dtc check, check the circuit
listed for the dtc in the table below (refer to the appropriate
page).
Hint:
When the srs warning light remains on and the normal
system code is output, a decrease in the source voltage is
likely to occur. This malfunction is n ...
