P0563-BATTERY VOLTAGE HIGH - ESM
For a complete wiring diagram Refer to the Wiring Information
- When Monitored:
Continuously with the ignition in the run position.
- Set Condition:
When the monitored battery voltage rises above 16.0 volts.
Always perform the NAG1 Pre-Diagnostic Troubleshooting procedure before proceeding. NAG1 Pre-Diagnostic Troubleshooting Procedure
Theory of Operation
The Shift Lever Assembly monitors ignition voltage. The DTC will set, if the monitored battery voltage rises above 16.0 volts.
1. CHECK FOR CHARGING SYSTEM DTCS
1. With the scan tool, read Engine DTCs.
NOTE: This includes any one trip faults.
Are there any Engine Charging System DTCs present?
Yes
- Diagnose and repair the DTC(s).
- Perform NAG1 TRANSMISSION VERIFICATION TEST. NAG1 Transmission Verification Test
No
- Go To 2
2. VEHICLE WAS JUMP STARTED INCORRECTLY
1. Verify if the vehicle was jump started by another vehicle using a 24-volt charging system or incorrectly jump started with the 12 volt battery in series.
Was the vehicle jump started by another vehicle?
Yes
- This is the cause of the DTC. Erase the DTC and return the vehicle to the customer.
- Perform NAG1 TRANSMISSION VERIFICATION TEST. NAG1 Transmission Verification Test
No
- Go To 3
3. CHECK SYSTEM VOLTAGE
1. Start the engine and let idle for at least 10 seconds.
2. With the scan tool, monitor system voltage.
Is the system voltage above 16V for more than 5 seconds?
Yes
- Refer to Charging System and perform the appropriate test.
- Perform NAG1 TRANSMISSION VERIFICATION TEST. NAG1 Transmission Verification Test
No
- Go To 4
4. SHIFT LEVER ASSEMBLY
1. Reconnect all disconnected harness connectors.
2. With the scan tool, erase Shift Lever DTC's.
3. Start the engine and raise the engine speed to 2000 RPM.
4. With the scan tool, read Shift Lever DTC's.
Did the P0563-BATTERY VOLTAGE HIGH DTC reset?
Yes
- Replace the Shift Lever Assembly
- Perform NAG1 TRANSMISSION VERIFICATION TEST. NAG1 Transmission Verification Test
No
- Test Complete.
