PRELIMINARY INFORMATION
Subject:

Engineering Information – Engine No Crank/No Start Due to Discharged Battery

Models:

2014 Cadillac XTS

Attention: Proceed with this PI ONLY if the customer has commented about this concern AND the
PIE number is listed in GWM/IVH. If the customer has not commented about this
condition or the EI does not show in GWM/IVH, disregard the PI and proceed with
diagnostics found in published service information. THIS IS NOT A RECALL – refer to
the latest version of Service Bulletin 04-00-89-053 for more details on the use of
Engineering Information PIs.

Condition
Important: If the customer did not bring their vehicle in for this concern, DO NOT proceed with this PI.
Some customers may comment that the vehicle will not crank or start because the 12V battery is drained or dead.

Cause
GM Engineering is attempting to determine the root cause of the dead 12V battery concern. Engineering has a need
to gather information on vehicles PRIOR to repair that may exhibit this condition. As a result, this information will be
used to “root cause” the customer's concern and develop/validate a field fix.

Instructions
Important: DO NOT disconnect the 12V battery prior to making contact with the engineer.
If a vehicle that exhibits the above customer concern is found, please complete the following steps prior to
contacting the engineer listed below. DO NOT disassemble/repair or replace any parts other than those instructed
below prior to calling.
1. Take a static voltage measurement from post to post of the battery before jump starting or charging.
2. Perform a GR8 test to ensure the 12V battery is truly good.
3. Check all battery connections and grounds for proper torque.
4. How long did the vehicle sit prior to the dead 12V battery?
5. Contact TAC to get a case number and any DTCs to them.
