13. Momentarily connect ECM/PCM connector terminalA14 to body ground with a jumper wire s everal
times.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
Check for poor connections or loose terminals
attheA/CclutchrelayandtheECM/PCM.Ifthe
connections and the terminals are OK, check the
A/C compressor clutch relay (see page 22-70),
repair open in the wires between the ECM/PCM
(A14), the A/C compressor clutch relay, and other
A/C systems parts. 1. Start the engine, and let it idle.
2. Monitor the ALTERNATOR in the DATA LIST with
the HDS.
3. Check if the indicated percentage varies when the headlight switch is turned on.
The alternator signal circuit is OK.
Go to step 4.
4. Turn the headlight switch and ignition switch to LOCK (0).
5. Jump the SCS line with the HDS.
6. Disconnect the alternator 4P connector.
7. Disconnect ECM/PCM connector B (44P).
8. Check for continuity between body ground and ECM/PCM connector terminal B43.
Repair short in the wire between the ECM/
PCM (B43) and the alternator.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with

Before checking the idle speed, check these items: – The malfunction indicator lamp (MIL) has not been reported on, and there are no DTCs.
– Ignition timing
– Spark plugs
– Air cleaner
– PCV system
Apply the parking brake, and make sure the headlights are off.
1. Disconnect the evaporative emission (EVAP) canister purge valve connector (see step 5 on page
11-409).
2. Connect the HDS to the data link connector (DLC) (A) located under the driver’s side of the dashboard.
3. Make sure the HDS communicates with the ECM/ PCM. If it doesn’t, go to the DLC circuit
troubleshooting (see page 11-204).

Idle speed should be:
K20Z2 engine:
M/T 700 50 rpm
A/T 800 50 rpm (in P or N)
K20Z3 engine: M/T 750 50 rpm
Idle speed should be:
K20Z2 engine: M/T 780 50 rpm
A/T 800 50 rpm (in P or N)
K20Z3 engine: M/T 750 50 rpm
Procedure

Idle Speed Inspection (cont’d) ECM/PCM Idle Learn Procedure
4. Start the engine. Hold the engine speed at
3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, then let it
idle.
5. Check the idle speed without load conditions: headlights, blower fan, radiator fan, and air
conditioner off.
6. Let the engine idle for 1 minute with high electric load (A/C switch on, temperature set to max cool,
blower fan on high, and headlights on high beam).
NOTE: If the idle speed is not within specification,
dotheECM/PCMidlelearnprocedure(seepage
11-310). If the idle speed is still not within
specification, go to the symptom troubleshooting.
7. Reconnect the EVAP canister purge valve connector. The idle learn procedure must be done so the ECM/PCM
can learn the engine idle characteristics.
Do the idle learn procedure whenever you do any of
these actions:
Replace the ECM/PCM.
Reset the ECM/PCM.
Update the ECM/PCM.
Replace or clean the throttle body.
Disassemble the engine or the transmission.
NOTE: Erasing DTCs with the HDS does not require you
to do the idle learn procedure.
1. Make sure all electrical items (A/C, audio, lights, etc.) are off.
2. Reset the ECM/PCM with the HDS.
3. Turn the ignition switch to ON (II), and wait 2 seconds.
4. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, or until the
engine coolant temperature reaches 90 °C (194 °F).
5. Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include
its running time in the 5 minutes.

1. Check the PCV valve (A), the hoses (B), and the connections for leaks or restrictions.
2. At idle, make sure there is a clicking sound from the PCV valve when the hose between the PCV valve
and intake manifold is lightly pinched (A) with your
fingers or pliers.
If there is no clicking sound, check the PCV valve
washer for cracks or damage. If the washer is OK,
replace the PCV valve then recheck. 1. Check the PCV valve (A), hoses (B), and

24. Temporarily install the clutch disc onto the splines of the transmission mainshaft. Make sure the clutch
disc slides freely on the mainshaft.
25. Apply a light coat of super high temp urea grease (P/N 08798-9002) to the crankshaft pilot bushing (A).
26. Apply super high temp urea grease (P/N 08798-9002) to the splines (B) of the clutch disc (C),
then install the clutch disc using the clutch
alignment shaft (D) and the remover handle (E).
27. Install the pressure plate (A) and the mounting bolts (B) finger-tight. 28. Torque the mounting bolts (A) in a cri

pattern. Tighten the bolts in several steps to
prevent warping the diaphragm spring.
29. Remove the ring gear holder (B), the clutch alignment shaft (C), and the remover handle (D).
30. Make sure the diaphragm spring fingers are all the same height.
31. Do the release bearing inspection, and replace it if necessary.
