Code Meaning
The C1616 code indicates a problem with the Electronically Controlled System (ETACS) ECU, which is responsible for sending the cranking signal to the All Wheel Control (AWC) ECU via CAN communication.
You’ll need to understand how this error code is triggered to diagnose the issue. The ETACS ECU continuously monitors the cranking signal and uses error detection methods to identify any anomalies.
If the signal is set for five seconds or more while driving, the code is set. This is a result of faulty vehicle electronics integration, which can lead to intermittent starting issues and other symptoms.
Possible Causes
When the C1616 code is triggered, faulty vehicle electronics integration is likely the culprit. This could be due to various issues, including faulty electronics and wiring problems. Take a closer look at the possible causes listed below:
| Possible Cause | Description | Solution |
|---|---|---|
| Faulty ETACS ECU | Electronically Controlled System malfunction | Replace faulty ECU |
| Faulty Ignition Switch | Ignition switch malfunction | Replace faulty switch |
| ETACS ECU Harness Issue | Open or shorted harness | Repair or replace harness |
| ETACS ECU Circuit Issue | Poor electrical connection | Clean or replace connector |
| Faulty AWC ECU | All Wheel Control malfunction | Replace faulty ECU |
Remember to inspect related wiring harness and connectors, check for damaged components, and clean or replace corroded battery terminals to resolve the issue.

- You might notice a delay in engine cranking or stalling.
How to Fix
Fixing the C1616 code requires a thorough approach to identify and address the underlying issue.
You’ll need to check the possible causes, visually inspect the related wiring harness and connectors, and look for damaged components or broken pins.
Repair or replace faulty parts, such as the Ignition Coil or Crankshaft Position sensor.
Clean or replace corroded battery terminals to guarantee a stable connection.
By following these steps, you’ll be able to resolve the issue and get your vehicle running smoothly again.
Remember to consult your repair manual or a professional mechanic if you’re unsure about any part of the process.
C1616 Information
You’ve completed the repair steps for the C1616 code, and now it’s time to understand the code itself.
This code is related to the cranking signal system in your Mitsubishi vehicle. To better grasp this code, some key points are essential to examine:
Understanding the C1616 code requires a closer look at your Mitsubishi vehicle’s cranking signal system.
- The C1616 code is a diagnostic trouble code (DTC) that indicates a problem with the cranking signal system.
- It’s often diagnosed using car troubleshooting techniques and diagnostic tools like the AutoCodes app.
- The code can be triggered by a faulty Electronically Controlled System (ETACS) ECU, Ignition Switch, or other electrical issues.
- A thorough understanding of this code is vital for effective repairs and to prevent further damage to your vehicle’s systems.
- By combining your knowledge of car troubleshooting with the right diagnostic tools, you can quickly identify and fix the root cause of the C1616 code.
Common Symptoms
When your Mitsubishi vehicle’s cranking signal system malfunctions, it can lead to a range of frustrating symptoms.
You may experience intermittent starting issues, where the engine won’t crank when you turn the ignition key. In some cases, the engine may not start at all, leaving you stranded.
Faulty systems, such as the Electronically Controlled System (ETACS) ECU or the All Wheel Control (AWC) ECU, can cause these starting troubles.
You may also notice the Anti-Lock Brake System (ABS) Warning Light or the Engine Light is on, indicating a problem with the cranking signal system.
Diagnosing the Cause
To diagnose the cause of the C1616 code, start by reviewing the possible causes listed above, which include faulty components such as the Electronically Controlled System (ETACS) ECU, Ignition Switch, and All Wheel Control (AWC) ECU.
You’ll want to investigate each of these components to determine which one is causing the issue.
- Check the Ignition Switch for signs of failure, such as corrosion or wear.
- Perform a Wiring Inspection to identify any damaged or corroded wires.
- Verify the Electronically Controlled System (ETACS) ECU is functioning properly.
- Check for any signs of water damage or physical damage to the components.
- Consult a wiring diagram to certify all connections are correct.
Repair Steps
Now that you’ve identified the faulty component, it’s time to take corrective action.
Replace the faulty starter motor if it’s causing ignition issues. Inspect the ignition switch and repair or replace it if necessary.
Faulty starter motor? Replace it. Inspect and repair or replace the ignition switch if necessary to get your engine running smoothly.
Check the wiring harness and connectors for damage, corrosion, or poor connections. Repair or replace them as needed.
Clean or replace corroded battery terminals to guarantee a stable power supply.
Once you’ve completed these repairs, clear the code and test the system to confirm the issue is resolved.
