This PI has been revised to add model years. Please discard PIC3899.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
A no crank, no start condition with a Driver Information Center (DIC) message that displays "No FOB Detected" can be caused by a low battery state of charge (SOC). The Remote Control Door Lock Receiver (RCDLR) will not function if the battery SOC is below 9V.
Recommendation/Instructions:
Check the battery state of charge and if low, diagnose the cause of the weak battery prior to performing any other repairs.
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.
