D. Replace Engine or Powertrain Harness (Typical)

NOTE:
Only those vehicles that have corrosion found during the inspection in Section A. require wiring harness replacement. Very few vehicles are expected to require wiring harness replacement.

1. Disconnect the positive battery cable.

2. Remove the battery and battery tray.

3. Remove the air cleaner assembly.

4. Disconnect the affected PCM electrical connectors (if necessary).

5. Remove the Power Distribution Center (PDC) cover and rotate the PDC on its hinges to expose the connectors on the bottom of the PDC.

6. Disconnect the harness connectors that connect to the PDC.

7. Disconnect the ground eyelets.

8. Disconnect the following items located in the engine compartment as necessary:

a. injector harness.

b. camshaft position sensor.

c. speed control servo.

d. upstream and downstream oxygen sensors.

e. leak detection pump.

f. oil pressure sensor.

g. starter battery positive wire (B+)

h. purge solenoid.

i. idle speed motor.

j. throttle position sensor.

k. intake air temperature sensor.

l. air conditioning transducer switch.

m. transaxle solenoid connector.

n. input and output speed sensor.

o. PRNDL switch connector.

p. crankshaft position sensor.

q. starter solenoid.

r. generator field wire connector.

s. generator battery positive wire.

t. air conditioning clutch coil.

9. Remove the old wiring harness from the vehicle.

10. Place the new wiring harness into position.

11. Connect the wiring harness to the following items located in the engine compartment as necessary:

a. purge solenoid.

b. idle speed motor.

c. throttle position sensor.

d. intake air temperature sensor.

e. air conditioning transducer switch.

f. injector harness.

g. camshaft position sensor.

h. speed control servo.

i. upstream and downstream oxygen sensors.

j. leak detection pump.

k. oil pressure sensor.

l. starter battery positive wire (B+)

m. transaxle solenoid connector.

n. input and output speed sensor.

o. PRNDL switch connector.

p. crankshaft position sensor.

q. starter solenoid.

r. generator field wire connector.

s. generator battery positive wire.

t. air conditioning clutch coil.

12. Connect the ground eyelets.

13. Connect the harness connectors that connect to the PDC.

14. Rotate the PDC into position and install the cover.

15. Route the remainder of the harness to the PCM location.

16. Carefully reconnect the PCM connector(s). This may take several attempts. Be sure to insert the connector straight into the module. If the connector is not inserted straight into the module, it may cause the seal to move out of place.

17. Verify that all seals are in place (Figure 2).

18. For RS/CS vehicles, install the left side fender shield.

19. Install the air cleaner assembly.

20. Install the battery tray and battery.

21. Connect the positive battery cable and then the negative battery cable.

22. Continue with Section F - PCM/Vehicle Data Set-up.
