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 PCM CONFIGURATION is successful,
the PCM stores the DTC P0602 and
illuminates the MIL. (System is normal.)
Clear the DTC P0602 using WDS or
equivalent after PCM CONFIGURATION.
Note
• MIL goes off after three drive cycles with no failure. (DTCs remain in PCM.)
6. Retrieve DTCs 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 F43 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
