The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
No crank / no start condition. The concern may be intermittent.
Recommendation/Instructions:
This can be caused by a poor solder joint between the ignition main relay and the printed circuit board. The ignition main relay is not serviceable. If voltage checks identify a bad ignition main relay, it will be necessary to replace the Underhood Bussed Electrical Center (UBEC) to repair this condition.
A correction of this condition has been implemented into production as of November 30th, 2005.
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.
