Error Code P2696: What It Means & What To Do?

<<See All OBD Codes

Is your vehicle engine performance decreasing and you notice an increase in the fuel consumption and exhaust emissions? Do you notice the Malfunction Indicator Light illuminated on the dashboard? If there are faults in identifying the fuel injector, then P2696 fault code is definitely going to trigger up.

Each fuel injector has a six-digit alphanumeric correction code. The correction code is printed on the intake side of the fuel injector and is used to identify injector calibration. When replacing any fuel injectors, this code must be entered into the vehicle’s Engine Control Module (ECM) using a diagnostic scan tool. In addition, if a new ECM is installed, a diagnostic scan tool is used to program all six of the injector codes from the original fuel injectors into the new ECM.

Thus, whenever any injector is found to be incompatible with the control module, OBD code P2696 may be triggered.

What causes this problem with the Injector Data Incompatible?

• Glow Plug Control Module (GPCM) programming fault
• PCM programming fault
• Fuel injector nor working
• Injector wiring, connector and harness damaged

1. Powertrain Control Module – PCM program faults can lead to misinterpretation of data causing wrong OBD codes to get stored in the system, leading to vehicle showing erratic behaviour. Thus, it is important to repair, replace and reprogram the PCM and its components.
2. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.
3. Fuel Injector – If the fuel injector is faulty, it will greatly affect the engine performance, fuel economy and increase the emissions. Thus, it is important to realise the faults and replace it quickly. Buy new fuel injector form us today!
4. Injector Connector – The injector may also not function properly due to damaged connector, making it incompatible with the PCM. Thus. Replace damaged connector and ensure that the injector is working properly.

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

• Various kinds of problems can occur on other CAN-equipped vehicles when the battery is disconnected or goes dead. The modules in the CAN system require a certain amount of voltage for their Keep Alive Memory settings. If this is lost, the module will forget these settings and may not function properly until it has time to relearn the lost data. In some cases, this requires a special relearn procedure using a scan tool because the module can't do the relearn by itself.
• And on some vehicles, the module may go to sleep and not wake up until it is pinged by a scan tool or the main gateway module (usually the body control module). Relearning procedures typically require a factory scan tool or a professional level aftermarket scan tool.
• One of the features of CAN and other network systems is that modules can send and receive "ok" signals to let the main control module know if they are working or not. In theory, this makes diagnostics easier. On the other hand, it also means that one misbehaving module may generate enough noise to disrupt the entire network causing a complete shutdown of the vehicle!
• Thus, if the fuel injector is replaced or the control module is replaced or reprogrammed, the unique identification number of every fuel injector needs to be reprogrammed in the system to it to identify them correctly and to maintain proper flow rate through them also.
• Also check for mechanical failure of the fuel delivery system and the fuel injector components. Inspect and replace damaged wiring and connectors first.
• Check for faulty sensor and circuit and replace them immediately.
• Always retest the system after every step of diagnosis to ensure proper repair.

Common Mistakes When Diagnosing The P2696 Code

Always follow the complete diagnostic procedure without skipping any steps is required as to avoid unneeded repairs. Monitor the fuel injection system and the exhaust system properly, before doing any replacements. P2696 is a severe damage causing code and it should be repaired at the earliest convenience. In rare cases where the vehicle runs poorly and the fuel economy goes down, caution is advised when driving to avoid any issues.
