The P06D1: Internal Control Module Non-Volatile Random Access Memory (NVRAM) Failure refers to a failure within the non-volatile random access memory (NVRAM) of the control module, which is responsible for storing critical data even when the vehicle is turned off. This issue could be caused by a fault in the control module or an electrical issue.
P06D1 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P06D1: Internal Control Module Non-Volatile Random Access Memory (NVRAM) Failure |
| Is it serious? | Yes, as the failure of NVRAM can cause loss of important data, affecting the vehicle’s performance and control systems. |
| Possible causes | – Failure of internal NVRAM in control module – Control module fault – Electrical issue |
| How to diagnose? | – Check internal NVRAM for faults – Inspect electrical connections – Replace control module if necessary |
P06D1 Meaning
The P06D1 code is triggered when there is a failure in the non-volatile random access memory (NVRAM) of the control module. The NVRAM stores important data, such as vehicle settings and fault codes, even when the vehicle is powered off. A failure in the NVRAM can lead to the loss of critical information, affecting the vehicle’s operation and diagnostic systems.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional control module-related codes that may provide further insight into the NVRAM failure. | OBD-II Scanner |
| Check NVRAM Status | Use diagnostic tools to check the status of the NVRAM in the control module, ensuring it is functioning as expected and storing data properly. | Diagnostic Tool |
| Inspect Electrical Connections | Visually inspect the electrical connections to the control module for signs of damage, loose connections, or corrosion that could cause NVRAM failure. | Flashlight, Multimeter |
| Test the Control Module | If no electrical issues are found, test the control module for proper operation. If the NVRAM is faulty, the entire control module may need replacement. | Diagnostic Tool |
| Replace the Control Module | If the control module is found to be faulty, replace it with a new or reconditioned module to restore proper function. | Replacement Parts, Standard Tools |
| Clear Code and Retest | After repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to confirm the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P06D1 code has not returned. | OBD-II Scanner |
