Crankshaft

Inspection

• Clean the crankshaft oil passages with pipe cleaners

or a suitable brush.

• Check the keyway and threads.

Alignment

• Measure runout on all main journals to make sure the

crankshaft is not bent.

• The difference between measurements on each journal

must not be more than the service limit.

Crankshaft Total Runout:

Standard (New): 0.020 mm (0.0008 in) max.

Service Limit: 0.030 mm (0.0012 in)

DIAL INDICATOR

Rotate two complete

revolutions.

Support with lathe-

type tool or V-blocks.
Out-of-Round and Taper

• Measure out-of-round at the middle of each rod and

main journal in two places.

• The difference between measurements on each journal

must not be more than the service limit.

Journal Out-of-Round:

Standard (New): 0.004 mm (0.0002 in) max.

Service Limit: 0.010 mm (0.0004 in)

Measure taper

at edges.

Measure out-of-

round at middle.

• Measure taper at the edges of each rod and main

journal.

• The difference between measurements on each journal

must not be more than the service limit.

Journal Taper:

Standard (New): 0.005 mm (0.0002 in) max.

Service Limit: 0.010 mm (0.0004 in)ProCarManuals.com

6. After completing your tests, reinstall both PCM's, and destroy the temporary key.

If the inspection for a particular code requires voltage or resistance checks at the PCM connectors, remove the right

door sill molding. Pull the carpet back to expose the PCM. Unbolt the PCM cover, and connect the backprobe sets and

a digital multimeter as described below. Check the system according to the procedure described for the appropriate code(s)

listed on the following pages.

Troubleshooting Procedures (cont'd)

IV. Known-Good PCM Substitution

Use the following procedure if you need a known-good PCM to test a vehicle. It allows you to swap an PCM from a

"donor" vehicle without having to program it to the test vehicle's ignition key.

1. Cut a temporary ignition key for the test vehicle with a non-immobilizer key blank.

2. Remove the PCM from the test vehicle.

3. Write the test vehicle's VIN on the PCM you just removed to avoid confusing it with the donor vehicle's PCM.

4. Remove the known-good PCM from the donor vehicle, and install it in the test vehicle.

5. Tape the donor vehicle's ignition key head-to-head to the test vehicle's temporary key. The PCM will recognize the code

from the donor vehicle's key and allow you to start the engine with the temporary key.ProCarManuals.com
