3. Make sure the HDS communicates with the ECM/ PCM and other vehicle systems. If it doesn’t, go to
the DLC circuit troubleshooting (see page 11-204). If
you are returning from DLC circuit troubleshooting,
skip steps 4 through 9, 20 through 25, and 28
through 30, and do these procedures after
replacing the ECM/PCM;
 Replace the engine oil (see page 8-10) and the engine oil filter (see page 8-11).
 Replace the ATF (A/T model) (see page 14-232).
 Clean the throttle body (see page 11- 344).
4. Select the PGM-FI system with the HDS.
5. Select the INSPECTION MENU with the HDS.
6. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the screen prompts.
NOTE: If the TP POSITION CHECK indicates FAILED,
continue with this procedure.
7. Select the REPLACE ECM/PCM MENU, then select READ DATA, and follow the screen prompts.
NOTE: Doing this step copies (READS) the engine oil life data from the original ECM/PCM so you can later
download (WRITES) it into the new ECM/PCM.
 If READ DATA indicates FAILED, continue with this procedure.
8. A/T model: Select the A/T system with the HDS.
9. A/T model: Select the REPLACE TCM/PCM MENU, then select READ DATA and follow the screen
prompts.
NOTE: Doing this step copies (READS) the ATF life data from the original PCM so you can later download
(WRITES) it into the new PCM.
 If READ DATA indicates FAILED, continue with this procedure. 10. Turn the ignition switch to LOCK (0).
11. Jump the SCS line with the HDS.
12. Do the battery removal procedure (see page 22-69).
13. Remove the cover (A).
14. Remove the bolts (D), then remove the ECM/PCM
(E).
15. Disconnect ECM/PCM connectors A, B, and C. NOTE: ECM/PCM connectors A, B, and C have
symbols (A= , B= , C= ) embossed on them for
identification.

24. A/T model: Select the A/T SYSTEM with the HDS.
25. A/T model: Select the REPLACE TCM/PCM MENU, then select WRITE DATA, and follow the screen
prompts.
NOTE: If the WRITE DATA indicates FAILED,
continue with this procedure.
26. Select IMMOBI system with the HDS.
27. Enter the immobilizer code that you got from the iN or use the ECM/PCM replacement procedure in the
HDS; it allows you to start the engine.

3. Inspect the drive belt (see page 4-30).
4. Make sure no material is blocking the air flow to the
A/C condenser.
5. Check the dust and pollen filter. Replace it if it is clogged (see page 21-75).
6. Check for kinks or sharp bends in the A/C lines and hoses, which can greatly reduce system
performance. Replace A/C lines and hoses if they
are kinked or damaged (see page 21-8).
7. Start the engine, turn the air conditioning system on, and allow it to run for a few minutes and reach
stable operation.
 Check that the A/C operates at each position of the blower fan switch (except OFF). If the A/C
does not operate, refer to the symptom
troubleshooting.
 Check that the A/C compressor clutch (A) is engaged. The pressure plate should be rotating
at the same speed as the pulley. If the pressure
plate does not engage, refer to the symptom
troubleshooting.
 Check that the A/C condenser fan (B) and radiator fan (C) operate when the A/C compressor clutch
is engaged. If either fan fails to operate when the
A/C compressor clutch is engaged, refer to the
symptom troubleshooting.
 Check that the engine idle speed is correctly maintained when the A/C is switched on and off
and the A/C compressor clutch is engaged and
disengaged. Recommended PAG oil: SP-10
P/N 38897-P13-A01AH: 120 mL (4 fl·oz)
It is important to have the correct amount of refrigerant
oil in the A/C system to ensure proper lubrication of the
compressor. Too little oil damages the compressor; too
much oil reduces the cooling capacity of the system,
and can produce high vent temperatures.
 To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other
refrigerant oils.
 Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture
absorption.
 Do not spill the refrigerant oil on the vehicle; it may damage the paint; if it gets on the paint, wash it off
immediately.
Add the recommended refrigerant oil in the amount
listed if you replace any of the following parts: ........
.............. ............ ........
..............
........
.............. ............ ........
..............
A/C condenser .50 mL (1 2/3 fl·oz)
Evaporator .40 mL (1 1/3 fl·oz)
Line or hose .10 mL (1/3 fl·oz)
Receiver/Dryer .10 mL (1/3 fl·oz)
Leakage repair .25 mL (5/6 fl·oz)
A/C compressor .Since the oil separator is
equipped inside the compressor
for this vehicle, oil drainage is
unnecessary at the time of
compressor replacement.
