1. Seat the balancer shaft by pushing it away from the
oil pump sprocket end of the oil pump.
2. Zero the dial indicator against the end of the balancer shaft, then push the balancer shaft back
and forth and read the end play. 3. Remove the pump housing.
4. Remove the baffle plate (A) and the upper balancer
shaft holder (with bearings) (B), then remove the

General Troubleshooting Information
A
A
The term intermittent failure means a system may have
had a failure, but it checks OK now. If the malfunction
indicator lamp (MIL) on the dash does not come on,
check for poor connections or loose terminals at all
connectors related to the circuit that you are
troubleshooting. If the MIL was on but then went out,
the original problem may have been intermittent.
Periodically, new ECM/PCM software or new service
procedures may become available. Always check
online for the latest software or service information
relatedtotheDTCsorsymptomsyouare
troubleshooting.
Open and short are common electrical terms. An open
is a break in a wire or at a connection. A short is an
accidental connection of a wire to ground or to another
wire. In simple electronics, this usually means
something won’t work at all. With complex electronics
(such as ECMs or PCMs) this can sometimes mean
something works, but not the way it’s supposed to.1. Start the engine, and check the MIL (A). NOTE: If the ignition switch is turned to ON (II), and
the engine is not started, the MIL stays on for
15 20 seconds (see page 11-69). 2. If the MIL stays on, connect the HDS to the data link
connector (DLC) (A) located under the driver’s side
of the dashboard.
3. Turn the ignition switch to ON (II).
4. 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).
5. Check the diagnostic trouble code (DTC) and note it. Also check the freeze data and/or on-board
snapshot data, and download any data found. Then
refer to the indicated DTC’s troubleshooting, and
begin the appropriate troubleshooting procedure.
NOTE: Freeze data indicates the engine conditions when the first malfunction, misfire, or fuel trim
malfunction that activated the MIL was detected.
 The HDS can read the DTC, freeze data, on-board snapshot, current data, and other engine control
module (ECM) or powertrain control module
(PCM) data.
 For specific operations, refer to the user’s manual that came with the HDS.
6. If no DTCs are found, go to MIL troubleshooting (see page 11-203).
If the MIL did not stay on but there is a driveability
problem, do the symptom troubleshooting.
Some of the troubleshooting requires you to reset the
ECM/PCM and try to duplicate the DTC. If the problem is
intermittent and you can’t duplicate the code, do not
continue through the procedure. To do so will only
result in confusion and possibly, a needlessly replaced
ECM/PCM. (cont’d)

11. Measure the depth of the rivets from the clutch disc lining surface (A) to the rivets (B) on both sides. If
the measurement is less than the service limit,
replace the clutch disc.
12. Remove the ring gear holder. 13. Inspect the ring gear teeth for wear and damage.
14. Inspect the clutch disc mating surface on the
flywheel for wear, cracks, and burning.
15. Measure the flywheel (A) runout using a dial indicator (B). Through at least two full turns with
pushing against the flywheel each time you turn it
to take up the crankshaft thrust washer clearance. If
the measurement is not within the standard,
replace the flywheel, and recheck the runout; go to
step 16.
16. Install the ring gear holder (A).
17. Loosen the flywheel mounting bolts in a cri sscross
pattern in several steps. Remove the bolts, then
remove the flywheel and the ring gear holder.

The electronic control system consists of the powertrain control module (PCM), sensors, and solenoid valves.
Shifting and lock-up are electronically controlled for comfortable driving under all conditions.
The PCM receives input signals from sensors, switches, and other control units, processes data, and outputs signals
for the engine control system and the A/T control system. The A/T control system includes shift control, grade logic
control, clutch pressure control, and lock-up control.
The PCM switches the shift solenoid valves and the A/T clutch pressure control solenoid valves ON and OFF to control
gear selection and torque converter clutch lock-up.
