DTC Descriptors
DTC B1517: Battery Voltage
Circuit/System Description
TheIPC monitors the system voltage to ensure that the voltage stays within the proper range. Damage to components and incorrect data may occur when the voltage is out of range.
Conditions for Running the DTC
This DTC shall run only if the IPC has power, ground, and the ignition is not in START mode.
Conditions for Setting the DTC
| • | The battery voltage falls below 8 volts for 8 seconds. |
| • | The battery voltage is greater 18 volts for 8 seconds. |
Conditions for Clearing the DTC
The current DTC will clear when battery voltage is between 8-18 volts for 2 seconds.

Circuit/System Verification
Engine running, accessories OFF, measure and record the battery voltage. The voltage should be between 12.6 and 15.0 volts.
Circuit/System Testing
- Ignition OFF, disconnect the harness connectors at the IPC.
- Test for less than 5 Ω between the ground circuit terminals listed below and ground.
| ⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
- Verify that a test lamp illuminates between the B+ circuit terminals listed below and ground.
| ⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. |
- If all circuits test normal, replace the IPC.
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic procedure.
