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

On rare occasions, a crank no start condition may be experienced. In most cases, this will be an intermittent concern that is more likely to occur in cold ambient temperatures. Upon inspection, DTCs U2105, U2106, and/or U2108 may be found with the Tech 2.

If the SI diagnostics do not isolate a cause for this concern and this can be verified, monitor the Powertrain Fuse for B+ during the concern. If B+ is not present during the concern, or if the concern can not be verified to monitor for B+, inspect for a poor connection at C1-B1 of IP Fuse Block Connector 1.
