P2600 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2600 can be defined as Coolant Pump "A" Control Circuit/Open. The coolant pump A (CP-A) is can generally be located mounted to the front of the engine, on top of the car engine, inside the wheel wells or sometimes even against the bulkhead. The CP-A would be operated by an electrical signal which would come from the powertrain control module.

The coolant pump "A" control circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the coolant pump "A" control circuit would not be as per the specifications set by the manufacturer. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Coolant Pump "A" Control Circuit/Open?

• Some flaws in the coolant pump
• Coolant pump harness might be opened or sometimes shorted
• Coolant pump circuit might have inadequate electrical connection
• Faulty powertrain control module 

1. Fuel Injector - Facing some issues in starting your vehicle? Poor idle issues? Failed emissions? These are all the symptoms of bad, faulty, leaking and clogged fuel injectors. It would be a good decision to replace your defective fuel injector with a new one online.
2. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
3. Automatic Transmission Module - A defective transmission module will affect the gear shift mechanism and also affect during acceleration and deceleration. This will lead to affected engine performance and fuel delivery system. Thus, replace faulty transmission module now!
4. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
5. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.

Here are some steps which you should follow in order to diagnose this fault code:

• A scanner is used by a mechanic to diagnose this fault code. The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data. If he happens to find any additional error codes, he has to address them as well. Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears. If the error code does not return, then there can be an erratic condition.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective. Make sure to retest the entire system after repairs are completed so that you achieve success. After that the ground wire and ground strap should be inspected and then monitor the coolant pump control relay.
• If no results have been found after these inspections, then a specialized CAN scanner should be hooked up. The control modules can be inspected with the help of diagnostic scanner.
• Now once any component has been restored, then the technician should stop the inspection, the trouble code should be reset. After that restart the vehicle and then inspect for the P2600 code. This is done so that the mechanics is alerted as soon as the problem is resolved.

Common Mistakes When Diagnosing The P2600 Code

• Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happens when one doesn't follow all the steps carefully.
• The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek the help of experienced diagnostician to avoid any mistakes.
