P0563-BATTERY VOLTAGE HIGH - ESM 

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article. 

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. See 
STANDARD PROCEDURE.  

The Shift Lever Assembly monitors ignition voltage. The DTC will set, if the monitored battery voltage rises 
above 16.0 volts. 

Possible Causes 

CHARGING SYSTEM DTCS
VEHICLE WAS JUMP STARTED INCORRECTLY
SHIFT LEVER ASSEMBLY

2007 AUTOMATIC TRANSMISSION NAG1 - Shifter Diagnostics - Nitro

  

Diagnostic Test 

1) CHECK FOR CHARGING SYSTEM DTCS 

With the scan tool, read Engine DTCs. 

Are there any Engine Charging System DTCs present?  

Yes  

Refer to the appropriate Engine Electrical Diagnostics article and perform the appropriate 
symptom.  

Perform NAG1 TRANSMISSION VERIFICATION TEST.  

No  

Go to 2).  

2) VEHICLE WAS JUMP STARTED INCORRECTLY 

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.  

No  

Go to 3).  

3) SHIFT LEVER ASSEMBLY 

Reconnect all disconnected harness connectors. 

With the scan tool, erase Shift Lever DTC's. 

Start the engine and raise the engine speed to 2000 RPM. 

With the scan tool, read Shift Lever DTC's.

Yes  

Replace the Shift Lever Assembly per the Service Information  

Perform NAG1 TRANSMISSION VERIFICATION TEST.  

No  

Test Complete.  

P0607-ECU INTERNAL PERFORMANCE - ESM 

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article. 

When Monitored: 

Continuously with the ignition in the run position. 

Set Condition: 

If the Shift Lever Assembly controller detects an invalid calibration (checksum value). 

Always perform the NAG1 Pre-Diagnostic Troubleshooting procedure before proceeding. See 
STANDARD PROCEDURE.  

The Shift Lever Assembly (SLA) Electronic Shift Module (ESM) performs various internal tests to verify 
proper controller operation. This DTC indicates that there is an issue with the Shifter's internal processor. 

Diagnostic Test 

1) SHIFTER LEVER ASSEMBLY 

View repair  

Repair  

Using the schematics as a guide, check the Shift Lever Assembly Control Module terminals for 
corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If 
no problems are found, replace the Shift Lever Assembly per the Service Information.  

Perform NAG1 TRANSMISSION VERIFICATION TEST.  

P0930-BTSI CONTROL CIRCUIT LOW - ESM 

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article.

Possible Causes 

SHIFTER LEVER ASSEMBLY

 

2007 Dodge Nitro R/T 

2007 AUTOMATIC TRANSMISSION NAG1 - Shifter Diagnostics - Nitro

  

When Monitored: 

Continuously with the ignition in the run position. 

Set Condition: 

The DTC will set if the high side driver detects a short to ground for 10 seconds. 

Always perform the NAG1 Pre-Diagnostic Troubleshooting procedure before proceeding. See 
STANDARD PROCEDURE.  

The brake switch signal must be active before the shift lever can be moved out of the park position. The Shift 
Lever Assembly (SLA) Electronic Shift Module (ESM) receives two brake switch signals. The first signal is a 
CAN C Bus message sent to the shift lever assembly. The second signal is a hard wired brake switch signal to 
the shift lever assembly. The CAN C Bus message is the primary brake switch signal and the hard wired signal 
serves as the backup brake switch signal. 

Diagnostic Test 

1) ENGINE DTCS PRESENT 

With the scan tool, read Engine DTCs. 

Are there any Engine brake DTCs present?  

Yes  

Refer to appropriate Engine Electrical Diagnostics article and perform the appropriate diagnostic 
procedure.  

Perform NAG1 TRANSMISSION VERIFICATION TEST.  

No  

Go to 2).  

2) ABS MODULE DTCS PRESENT 

With the scan tool, read ABS Module DTCs. 

Are there any ABS DTCs present? 

Possible Causes 

ENGINE BRAKE DTCS PRESENT
ABS DTCS PRESENT
(L51) BRAKE SWITCH SIGNAL SHORT TO GROUND
