The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Although technicians have sometimes swapped parts between vehicles to isolate service issues, with today's technology, there are some parts you cannot do this with. If you swap either the Instrument Panel Cluster or BCM between vehicles, you can cause a number of different PCM issues, as well as odometer issues and radio lock-ups.
Do not swap BCMs or Instrument Panel Clusters between vehicles on a Colorado, Canyon or a Hummer H3. If a BCM or an Instrument Panel Cluster needs replacing, ONLY use new SPO parts when replacing the BCM and utilize the Service Exchange Centers when replacing the Instrument Panel Cluster.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
