#PIT4787C: Approximate 150 To 200 mA Draw From The Power Steering Control Module - keywords battery electric motor PSCM - (Feb 18, 2009)


Subject: Approximate 150 to 200 ma Draw From The Power Steering Control Module


Models: 2007-2009 Chevrolet Cobalt, Equinox and HHR

2007-2009 Pontiac Torrent

2008-2009 Saturn VUE
--------------------------------------------------------------------------------

This PI was superseded to update models and Condition/Concern. Please discard PIT4787B.


--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
The vehicles listed above may have a 150 to 200 ma battery draw from the power steering control module. If the mega fuse for the power steering control module is removed, the draw may drop to around 20 - 25 ma. This can be due to the power steering control module staying awake for approximately 45 minutes. This may be a normal draw.

On the following vehicles: Equinox, Torrent, VUE and HHR SS only the power steering control module will stay awake for 45 minutes and then shut down.

On the Cobalt and HHR base model, the power steering control module may stay awake for up to 45 minutes. On these vehicles the PSCM module may stay awake based on the power steering motor temperature. The hotter the motor, the longer the module will stay awake (up to 45 minutes).

Recommendation/Instructions:
When diagnosing a battery draw, if the draw drops after removing the mega fuse for the power steering control module, do the following: Reinstall the mega fuse for the power steering control module and make sure to plug everything back in, then turn the ignition key on and then back off. Let the vehicle sit for up to 45 minutes and then re-check the battery draw readings. If the draw drops to around 20 - 25 ma, after 45 minutes, this is normal operation of the vehicle.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
A technician may encounter a vehicle with a low boost/power condition and/or DTC P0299 and or P0101 setting. This may be the result of a cracked or broken fitting at the turbocharger assembly.

Recommendation/Instructions:
It has been determined that the nipple for the turbocharger wastegate actuator may be damaged causing this condition. If this concern is noted please inspect the area on the underside of the turbo compressor housing for the wastegate actuator solenoid valve. The nipple (see CALLOUT #1) may have been damaged causing a loss of boost pressure. It may be necessary to remove the charge air duct for a closer inspection. See eSI "Turbocharger Wastegate Actuator Replacement" for solenoid replacement procedure.





This solenoid is available separate from the turbocharger and should be replaced as a sub assembly. Do not replace the turbocharger assembly.

--------------------------------------------------------------------------------

This PI was superseded to combine data from AIC3407A and to remove the 08 MY from list as these vehicles do not set the P0833 DTC. Please discard PIP3673D.
--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
Some customers may comment that the cruise control is inoperative and/or the MIL is on with DTC P0833 stored. The condition may not be duplicated by the dealer; however, the customer may have a repeat concern.

Recommendation/Instructions:
Check the "Top of Travel" or CCP switch for adjustment if your application is adjustable. Also check for possible intermittent connections in the clutch switch circuit.

It has been discovered in some applications that using a Tech II during circuit testing of the clutch and cruise switches may lead to false readings and improper diagnosis of the CCP switch. The Tech II may read APPLIED/RELEASE upon initial toggling of the switch, however repeated toggling may then lead the Tech II to indicate a steady APPLIED or RELEASED state.

Use a DVOM to check the clutch and cruise switches.

If no circuit concerns are found, verify that the customer's driving habits are not inducing the concern. This code can set (and the cruise control disabled) if the driver rests their foot on the clutch continuously and therefore prevents the pedal from reaching the top switch. This will keep the ECM from seeing transitions while they drive above and then below the vehicle speeds listed for setting the DTC. This can cause a false P0833 to set. An example of this occurring would be in slow moving stop and go traffic such as a construction zone or heavy traffic.

Important: Please make the customer aware of this scenario and advise to make an effort to refrain from resting their foot on the clutch pedal in these situations to avoid disabling the cruise control and/or setting DTC P0833.

Note: FOR THE FOLLOWING VEHICLES ONLY

If the technician has followed the SI procedure for adjustment/replacement of the clutch pedal position sensor this may make the switch too sensitive for some driver's habits. The PPS should be adjusted to reduce the sensitivity. This can be accomplished by watching the PPS change states with a Tech2 and adjusting the PPS so that the pedal must travel farther before engaging switch. (I.e. from 1/4 inch travel to 1/2 inch of travel when changing states.)
