ENTERING VIN DURING ECM (PCM)
REPLACEMENT AND/OR DTC P0630
Models:
All '04 ± '06 Models
TSIB REVISION NOTICE:
June 3, 2005: Content has been updated to include 2004 and 2006 model year
vehicles. Step 4 of the VIN Write Procedure (page 2) and step 3 of the VIN Read
Procedure (page 3) have been clarified to include RX 400h vehicles.
Previous versions of this TSB should be discarded.
All 2005 and subsequent model year Lexus vehicles have the VIN (Vehicle Identification
Number) stored in the Electronic Control Module (ECM) (SAE term: Powertrain Control
Module/PCM) non±volatile memory. The VIN is accessible on the data stream using the
Lexus Diagnostic Tester and can also be written to a new ECM (PCM) using a ªVIN
Read/Writeº utility.
Service ECMs (supply parts) are shipped without the VIN; therefore, as part of the ECM
(PCM) replacement procedure, the VIN must be written to the replacement ECM (PCM)
using the Diagnostic Tester utility function. Failure to write the VIN to the ECM (PCM) will
result in a M.I.L. ªONº condition and set DTC P0630: VIN Not Programmed or Mismatch ±
ECM (PCM).
It is very important to remember to enter the VIN on these vehicles. Vehicles with missing
VINs are subject to failing some state and local vehicle emissions Inspection and
Maintenance programs.
NOTE:
2004 model year vehicles which have been flash reprogrammed may contain updated
2005 model year OBD II logic. These vehicles will require VIN entry into the ECM (PCM)
after reprogramming.
2004 model year vehicles that have been flash reprogrammed.
All 2005 ± 2006 model year vehicles.
