4. Set the dial indicator to ª0º. Place it on the
mounting post of the gauging arbor with the
contact button touching the indicator pad. Force
the dial indicator downward until the needle has
made a half turn clockwise. Tighten down the dial
indicator in this position.

5. Position the plunger on the gauge plate. Move the
gauging arbor slowly back and forth and locate
the position at which the dial indicator shows the
greatest defection. At this point, once again set
the dial indicator to ª0º.
Repeat the procedure to verify the ª0º setting.

touch the gauging plate.Record the number the dial indicator needle
points to.

7. Record the pinion depth code on the head of the
drive pinion.
The number indicates a necessary change in the
pinion mounting distance. A plus number indi-
cates the need for a greater mounting distance
(which can be achieved by decreasing the shim
thickness). A minus number indicates the need
for a smaller mounting distance (which can be
achieved by increasing the shim thickness). If ex-
amination reveals pinion depth code ª0º, the pin-
ion is ªnominalº.

ENGINE DRIVEABILITY AND EMISSIONS
Diagnostic Trouble Code (DTC) P1625 PCM Unexpected Reset
Circuit Description
The powertrain control module (PCM) monitors
unexpected PCM reset. This will not turn on MIL light on,
only records code DTC P1625.
Conditions for Setting the DTC

Clock or COP reset.
Action Taken When the DTC Sets

The PCM will not illuminate the malfunction indicator
lamp (MIL).

The PCM will store conditions which were present
when the DTC was set as Failure Records only. This
information will not be stored as Freeze Frame data.
Conditions for Clearing the MIL/DTC

DTC P1625 can be cleared by using the Tech 2 ªClear
Infoº function or by disconnecting the PCM battery
feed.
Diagnostic Aids
Check for the following conditions:

P1625 alone stored does not need diagnosis. Clear
DTC code.

INSPECTION REPAIR
Make the necessary adjustments, repairs, and part replacements if excessive wear or damage is discovered
during inspection.
1. Remove the gasket and any other material adhering to
the upper surface of the cylinder block.
Be very careful not to allow any material to accidentally
drop into the cylinder block.
Be very careful not to scratch the cylinder block.
2. Carefully remove the oil pump, Rear Oil Seal retainer,
and oil pan installation surface seal.
3. Wipe the cylinder block clean.
Cylinder Liner Projection Inspection
1. Hold a straight edge 1 along the top edge of the cylinder
liner to be measured.
2. Use a feeler gauge 2 to measure each cylinder liner
projection.
The difference in the cylinder liner projection height
between any two adjacent cylinders must not exceed
0.03 mm (0.0012 in).
0.0 – 0.1 (0.0000 – 0.0039)
mm(in.) Standard
Flatness
1. Remove the cylinder body dowel.
2. Set the cylinder liner remover to the cylinder liner.
3. Check that the remover shaft ankle is firmly gripping the
cylinder liner bottom edge.
4. Slowly turn the remover shaft handle counterclockwise
to pull the cylinder liner free.
Cylinder Liner Remover Ankle: 5-8840-2304-0
Cylinder Liner Remover: 9-8523-1169-0
NOTE:
Take care not to damage the cylinder body upper during the
cylinder liner removal procedure.
5. Use a straight edge 1 and a feeler gauge 2 to measure the
four sides and the two diagonals of the cylinder body
upper face.
If the measured values exceed the limit, the cylinder
body must be replaced.
