2000 Chevrolet Cavalier Base, 4D Sedan, 2.4 TSECTION Removal Procedure

WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: In order to prevent internal damage to the PCM, the ignition must be OFF when disconnecting or reconnecting the PCM connector.

Service should normally consist of either replacement of the PCM or EEPROM re-programming.

If the diagnostic procedures call for the PCM to be replaced, the PCM should be inspected first in order to verify the PCM is the correct part. DTC P0602 indicates the EEPROM programming has malfunctioned. When DTC P0602 is set, re-program the EEPROM.

Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.
NOTE: Do not touch the PCM connector pins or soldered components on the circuit board in order to prevent possible electrostatic discharge (ESD) damage. Do not remove the integrated circuit boards from the carrier.
Push down the locking tab and pull up on the release lever and disconnect the PCM harness connectors (1).
Press the PCM retaining tab.
Lift the PCM (2) from the PCM bracket (3).
