| Subject: | Service Engine Soon (SES) Lamp Illuminated with P0130 and/or P0150 Set in
ECM Memory (Install Updated ECM Calibration if Required) |
| Models: | 2000 - 2002 Saturn L-Series vehicles equipped with V6 (L81) engines |
Condition
Some customers may comment the service engine soon (SES) lamp is illuminated.
Cause
If vehicle was driven and engine shut off before reaching full operating temperature,
the ECM calibration may not heat the O2 sensors sufficiently during the next ignition
cycle causing DTC P0130 and/or P0150 to set in ECM memory.
Correction
To correct this condition refer to the Engine/Emission Controls section of the
appropriate model year L-Series L81 Engine Service Manual and follow the trouble tree
and diagnostic aids for DTC P0130 and/or P0150. After diagnosis is complete and any
repairs have been completed, refer to the following procedure to determine if an updated
calibration is required.
Before installing new ECM calibration, make sure the Service Stall System (SSS)
version is 10.5 or greater.
Procedure
- Connect Scan Tool to the vehicle.
- Navigate to the 3.0L (VIN R) menu.
- Select ID INFORMATION.
- Select ENGINE INFORMATION.
- Read ECM CALIBRATION.
On 2000 model year vehicles:
| • | If ECM calibration ID number is one of the following: 610601, 610602,
620101, 620102, 640104, 640301, 640704, or 640901, reprogram the ECM with the latest
2000 model year calibration available on the Saturn Service Stall System (SSS). (Refer
to "Service Programming System [SPS]" in the Saturn Service Stall [SSS]/Tech 2 User
Guide for reprogramming procedures.) This calibration can be found on software CD
version 10.5 and higher. |
| • | If ECM calibration is not one of the following ID numbers: 610601, 610602,
620101, 620102, 640104, 640301, 640704, or 640901, do not reprogram the ECM because
the ECM already has a calibration installed to address this condition. Refer to additional
diagnostic information in the "Engine/Emissions Controls" section of the 2000 L-Series
L81 Engine Service Manual. |
On 2001 model year vehicles:
| • | If ECM calibration ID number is one of the following: 630102, 740104,
740302, 740704, or 740901, reprogram the ECM with the latest 2001 model year calibration
available on the Saturn Service Stall System (SSS). (Refer to "Service Programming
System [SPS]" in the Saturn Service Stall [SSS]/Tech 2 User Guide for reprogramming
procedures.) This calibration can be found on software CD version 10.5 and higher. |
| • | If ECM calibration is not one of the following ID numbers: 630102, 740104,
740302, 740704, or 740901, do not reprogram the ECM because the ECM already has a
calibration installed to address this condition. Refer to additional diagnostic information
in the "Engine/Emissions Controls" section of the 2001 L-Series L81 Engine Service
Manual. |
On 2002 model year vehicles:
| • | If ECM calibration ID number is one of the following: 840601, 840704,
or 840901, reprogram the ECM with the latest 2002 model year calibration available
on the Saturn Service Stall System (SSS). (Refer to "Service Programming System [SPS]"
in the Saturn Stall [SSS]/Tech 2 User Guide for reprogramming procedures.) This calibration
can be found on software CD version 10.5 and higher. |
| • | If ECM calibration is not one of the following ID numbers: 840601, 840704,
or 840901, do not reprogram the ECM because the ECM already has a calibration installed
to address this condition. Refer to additional diagnostic information in the "Engine/Emissions
Controls" section of the 2002 L-Series L81 Engine Service Manual. |
