The PCM did not receive a valid vehicle identification number (VIN) during reprogramming. Check for all other module Diagnostic Trouble Codes (DTCs) or related symptoms. Diagnose all other module Diagnostic Trouble Codes (DTCs) before diagnosing this DTC . Reprogram the BCM , instrument cluster, and PCM using as built data. Refer to Flash EEPROM , Programming The VID Block For A Replacement PCM , to reprogram the PCM .
PCM P064F:00	Unauthorized Software/Calibration Detected: No Sub Type Information	Sets when the PCM detects an unauthorized calibration.
PCM P160A:00	Control Module Vehicle Options Reconfiguration Error: No Sub Type Information	Sets when the PCM detects a mismatch in configuration data and programmable parameters between the PCM and BCM . Reprogram or update the calibration. If the PCM already has the latest calibration, carry out the relearn vehicle data procedure on the scan tool. Check for other Diagnostic Trouble Codes (DTCs) or drive symptoms for further action.
PCM P161C:00	Automatic Engine Shutdown Mismatch with Vehicle Configuration: No Sub Type Information	Sets when the IPC detects a mismatch in configuration data and programmable parameters between the PCM and the IPC .
PCM P1635:00	Tire/Axle Out of Acceptable Range: No Sub Type Information	Sets when the PCM detects the tire and axle information contained in the vehicle identification (VID) block does not match the vehicle hardware. Using the scan tool, view the tire and axle parameters within the VID block. They must match the vehicle hardware.
PCM P1639:00	Vehicle ID Block Corrupted, Not Programmed: No Sub Type Information	Sets when the PCM detects the VID block is not programmed or the information within is corrupt. Program the PCM to the most recent calibration available. The VID block must be programmed. Refer to Flash EEPROM , Making Changes to the VID Block.
PCM P1935:00	Brake Switch/Sensor Signal: No Sub Type Information	Sets when the PCM does not receive the ABS message within the defined amount of time. The PCM continuously monitors the CAN for messages from the ABS module. Check for other ABS Diagnostic Trouble Codes (DTCs) or ABS related symptoms. Diagnose all other ABS Diagnostic Trouble Codes (DTCs) or ABS related symptoms first.
PCM P264F:00	Engine Serial Number Not Programmed or Incompatible: No Sub Type Information	Sets when the PCM does not receive a valid engine serial number during reprogramming. The VID block must be programmed. Refer to Flash EEPROM , Programming VID Block. If the PCM does not allow reprogramming of the VID block, reflashing of the PCM is required.
PCM U2100:00	Initial Configuration Not Complete: No Sub Type Information	Sets when the PCM detects a programming error within the vehicle identification (VID) block. Program the VID block. Refer to Flash EEPROM , Making Changes to the VID Block. If the PCM does not allow reprogramming of the VID block, reflashing of the PCM is required.
PCM U2101:00	Control Module Configuration Incompatible: No Sub Type Information	Sets when the PCM detects the RAM is corrupt. Reprogram or update the calibration. Check for other Diagnostic Trouble Codes (DTCs) or drive symptoms for further action. Check for aftermarket performance products. Refer to Flash EEPROM , Programming the VID Block for a replacement PCM .
PCM U2200:00	Control Module Configuration Memory Corrupt: No Sub Type Information	Sets when the PCM detects a programming error within the vehicle identification (VID) block. Program the VID block. Refer to Flash EEPROM , Making Changes to the VID Block. If the PCM does not allow reprogramming of the VID block, reflashing of the PCM is required.

Removal

NOTICE: Suspension fasteners are critical parts that affect the performance of vital components and systems. Failure of these fasteners may result in major service expense. Use the same or equivalent parts if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Tighten fasteners as specified.

NOTE: Removal steps in this procedure may contain installation details.

With the vehicle in NEUTRAL, position it on a hoist.
Refer to: Jacking and Lifting (100-02 Jacking and Lifting, Description and Operation).

NOTICE: Do not use power tools to remove or install the stabilizer bar
