CONTROL SYSTEM
PCM CONFIGURATION
A6E394018880W03
1. Connect the WDS to DLC-2.
2. Set up the WDS (including the vehicle
recognition.)
3. Select “Module programming.”
4. Select “Programmable module installation.”
5. Select “PCM” and perform procedures according
to directions on the WDS screen.
Note
•
If the PCM is replaced with a new one, the
PCM stores DTC P0602 and illuminates the
MIL even though no malfunction is detected.
When the PCM CONFIGURATION is
performed, then the stored DTC P0602 is
deleted.
6. Retrieve DTC’s by the WDS or equivalent, then verify that there in no DTC present.
•
If DTC is present, perform applicable DTC inspection.

INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION
A6E394018845W01
Resistance Inspection
Note
•
Perform the following inspection only when directed.
1. Disconnect MAF/IAT sensor.
2. Measure the resistance between the MAF/IAT
sensor terminals D and E using an ohmmeter.
•
If not as specified, replace the MAF/IAT
sensor.
•
If the MAF/IAT sensor is okay, but the IAT
PID are out of specification, perform the
“Circuit Open/Short Inspection”.
Specification
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See F–43 PCM
REMOVAL/INSTALLATION .)
2. Inspect the following wiring harnesses for open or
short. (Continuity check)
Open circuit
•
If there is no continuity, the circuit is open. Repair
or replace the harness.
— MAF/IAT sensor terminal D (harness-side)
and PCM terminal 2E (harness-side)
— MAF/IAT sensor terminal E (harness-side)
and PCM terminal 2H (harness-side)
Short circuit
•
If there is continuity, the circuit is shorted. Repair
or replace the harness.
— MAF/IAT sensor terminal E (harness-side) and power supply
— MAF/IAT sensor terminal D (harness-side) and power supply
— MAF/IAT sensor terminal D (harness-side) and body GND
