P2536 - OBD Trouble Code

<<See All OBD Codes

Do you find any issue with the battery control module? Then there is a chance that the P2536 error is stored in your vehicle. As you turn the key on, the battery voltage will be sent to each of the vehicle’s electrical systems. This voltage will be looked after by the transmission control module to make sure it is perfect. If the transmission control module finds out that the voltage is less, then the P2536 error will be set.

The proper monitoring of the ignition switch accessory position signal is done by the powertrain control module. If the factory specification is not met by the ignition switch accessory position signal then the error code will be set by the PCM.

What causes this problem with the Ignition Switch Accessory Position Circuit?

• Damaged ignition switch.
• There might be an opening or the ignition switch harness might have a short circuit.
• The electrical connection of the ignition switch circuit might be weak.

1. Powertrain Control Module - Does your engine turn off without any reason? Then it’s a high time to replace your PCM as it can be faulty.
2. Ignition Switch - One of the common symptoms of a defective ignition switch is the engine misfire. Get a new ignition switch from PartsAvatar and replace it quickly.
3. Battery Control Module - The batteries power is usually monitored by the battery control module of the batteries. If you are looking to avoid the P2536 error in your vehicle, then you must replace the damaged battery control module.
4. Starter Motor - The starter motor can be faulty if the engine fails to starts even after turning on the key. Avoid the P2536 error by changing the faulty error.
5. Transmission Control Module - If your vehicle is stuck in the neutral or same gear then the transmission control module can be damaged. Change it quickly.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2536 here:

Common Symptoms

• As the DPF restores, the light will remain the same or light erratically. The engine will be inactive as you accelerate.
• Defective PCM.
• The ECU will return to the ‘limp home mode’ if the DPF is not corrected, until and unless the situation is made clear.
• The vehicle will refuse to accelerate while starting

Here are some ways with the help of which you will be able to correct the OBD Code P2536

• You have to replace the ignition switch.

Here are some steps which you should follow in order to diagnose this fault code P2536:

• The voltage from the battery and cables is almost transferred to every system in the vehicle.
• This voltage is commonly referred to as “switched voltage”. In most scenarios, the mechanized actuator is turned with the help of a keyed cylinder.
• The actuator will turn electronic switch which is made of heavy grade contacts which can withstand more current draw.
• The input side of the ignition switch receives battery voltage through fused primary wires and cables.
• When you turn off the ignition switch, the system which functions with switched voltage is perfectly neutralized.
• This saves the battery voltage and makes transportation easy.
• Once the switch is fixed to the accessory or auxiliary position, switched voltage will be sent to the system which is linked with stationary use.
• Activate the starter by fixing the ignition switch in the start position and start the engine.
• The voltage is almost sent to all switched voltage system during run position.
• To diagnose this error, you need multiple tools as they can help you to know where the error is stored.
• Diagnose the code with the help of a scanner and DVOM.
• A manufacturer’s service manual will be essential.
• Carefully check the ignition switch wires and connectors
• The damaged wires, connectors, and other components have to be separated and repaired.
• After each successful diagnosis, recheck the system.
• Attach a scanner to the vehicle if every component is in proper working conditions and then retrieve both the stored codes and freeze frame data.
• This is highly helpful to find if there are any irregular conditions which made this error code to get stored in the vehicle.
• Clear all codes and retest the vehicle to see if any error has occurred.
• This will help you to know if the condition was irregular. Clear all codes and retest the vehicle to see if an error appears again.
• The condition will be erratic if the code does not show up instantly.
• In one such situation, you have to worsen the condition of the vehicle before proceeding for further diagnosis as this is a challenging task.
• Check for battery voltage and ground signals at the ignition switch, if the code shows up again.
• With the help of DVOM check for openings in the ground or battery voltage circuit for continuity and resistance in both the circuits.
• Clear all codes and retest the vehicle to see if any error has occurred.
• Pay close attention to the fuses and fusible links and make sure to locate the reason for the failure of the fuse and fusible links to avoid further damage.
• With the help of the manufacturer’s wire diagram test the circuit for resistance and continuity and relate your findings with that of the manufacturer.
• Fix each of the circuits, connectors, and components which fails to comply with the manufacturer’s specification.
• Make sure that the repair was successful once the system was re-checked.

Common Mistakes When Diagnosing the P2536 Code

• Malfunctioning of the ignition switch.
• An issue with the electrical wires.
• Damaged TCM.
