P0610 OBD-II Trouble Code: Control Module Vehicle Options Error

Check Engine Light

P0610 code definition

When the PCM (powertrain control module) or one of its supporting control modules detects a control module vehicle option error, it will detect and record a P0610 code. Once the code has stored, the Check Engine light will illuminate.

What the P0610 code means

Basically, the P0610 code indicates that there’s been an internal memory fault in the PCM. This fault could be detected by the PCM itself, or by a number of supporting control modules, including but not limited to:

  • Antilock brake control module
  • Turbo control module
  • Body control module
  • Transmission control module
  • Anti-theft control module
  • Traction control module
  • Fuel injection control module
  • Instrument panel control module
  • Proximity alert control module
  • Climate control module

For some models, a single detected error can result in the P0610 code being stored, but for others it can take as many as eight drive cycles’ worth of errors to record the code.

What causes the P0610 code?

The most likely problem that can trigger a P0610 code is an open or shorted PCM circuit. This problem may also be caused by a faulty PCM, as well as:

  • Corroded or damaged wiring or connectors to the CAN (control area network) bus harness
  • A loose ground strap for the control module
  • A defective or damaged CAN bus

What are the symptoms of the P0610 code?

In addition to the Check Engine light coming on, there are also a few other symptoms that might occur in association with a P0610 code. These include:

  • A negative impact on fuel efficiency
  • Harsh shifting
  • Lack of acceleration
  • A rough idle
  • Stalling at idle

How does a mechanic diagnose the P0610 code?

With an OBD-II scanner, a mechanic can read which codes the PCM has stored and see if there are any related codes that might point to the root of the problem. After reading all currently saved codes, they will do a visual inspection of all relevant wiring and circuits. They may then use an ohmmeter to test the wiring and connectors to ensure that there isn’t an open or shorted circuit.

They’ll then move on to test the PCM, the CAN bus, and any other relevant components. After each test and/or repair, they will clear all codes and retest the vehicle to see if the code is set again or if it’s been resolved.

Common mistakes when diagnosing the P0610 code

the P0610 code is often caused by an electrical failure or communication failure, which means that it can set off numerous other codes and symptoms. If you attempt to address these codes and symptoms first, you’re likely to waste a lot of time, energy, and money. Instead, it’s smart to diagnose the cause of the P0610 code first and then move on to other problems if they aren’t solved when you resolve this code.

How serious is the P0610 code?

A memory fault in the PCM can lead to a number of other symptoms, including problems that can significantly affect the drivability of the vehicle. Failing to resolve this issue can result in serious engine problems later on, and it can be dangerous to drive a vehicle that’s displaying some or all of the symptoms associated with a P0610 code.

What repairs can fix the P0610 code?

In most cases, the repairs necessary to fix a P0610 code will include one or more of the following:

  • Replacing or repairing damaged wiring or connectors to the CAN bus harness.
  • Repairing a loose ground strap for the control module.
  • Replacing a defective CAN bus.
  • Replacing, repairing, or reprogramming the PCM.

Additional comments for consideration regarding the P0610 code

Even if you do not notice any difference in the performance of your vehicle, it’s essential to get this issue resolved immediately. A P0610 code can lead to serious trouble down the road, and it can keep your vehicle from passing an OBD-II emissions test, as well.
