Bulletin No.: PIT5065E
Date: Jan-2013
Subject:
SES Indicator Due To DTC P0690 - Reprogram ECM
Models:
2010 - 2011 Chevrolet Equinox
2010 - 2011 GMC Terrain
Built Prior to March 15, 2011
This PI was superseded to update admin details. Please discard PIT5065D.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
Some customers may comment on a SES indicator coming on. During diagnosis a technician may find DTC P0690 set in the ECM for the KR75 ECM relay. The
code will clear and may not return during diagnostic testing.
Engineering has determined that the ECM is still monitoring the KR75 ECM relay during ignition/key off while the ECM is going to sleep. When the ECM detects
voltage from the relay one time, DTC P0690 sets and the SES indicator is illuminated. This DTC is supposed to indicate a stuck closed relay but engineering
has determined that a software anomaly may cause it to falsely set on vehicles built prior to March 15, 2011.
Recommendation/Instructions
If SI diagnosis does not isolate the cause of this concern, reprogram the ECM with the latest TIS2Web calibrations, which are designed to address this
concern.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
