Circuit/System Verification
Danger: The Volt Battery Pack will utilize an exchange program. Please consult the most recent revision of bulletin/PI #PIP4841, available in Service Information (SI), for a list of approved Volt Battery Pack service procedures. Components that may be removed and serviced without exchanging the complete battery pack are identified in the bulletin/PI. Please contact the GM Technical Assistance Center (1-877-446-8227) if you have any questions.
1. Verify that no other DTCs are set.
• If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.
2. Verify the K36 inflatable restraint sensing and diagnostic module is programmed with the correct software calibration.
• If the correct software is not installed, program the K36 inflatable restraint sensing and diagnostic module.
3. Ignition ON, observe the scan tool Crash Event Detected parameter. The reading should be No.
• If the reading is yes, perform the Clear Secured High Voltage DTCs function.
4. If DTC P1F17 resets and no other DTCs are set, replace the K114B hybrid powertrain control module 2.
