B0035 and B0036: Airbag Deployment System Closed or Shorted to Ground and ADS Open or Missing or Shorted to Battery

DTC codes B0035 and B0036 are both related to the air deployment system (ADS). The ADS is a safety system that is designed to deploy airbags in the event of a collision.

• B0035 - ADS Closed/Shorted to Ground: is set when the powertrain control module (PCM) detects a problem with the ADS that is causing the ADS to be shorted to ground.
• B0036 - ADS Open/Missing/Shorted to Battery: is set when the PCM detects a problem with the ADS that is causing the ADS to be open, missing, or shorted to battery voltage.

What are the causes of these DTC codes?

There are a number of possible causes for DTC codes B0035 and B0036, including:

• Damaged ADS wiring harness: The ADS wiring harness can be damaged by road debris, heat, or corrosion. This can cause a short circuit or open circuit in the ADS circuit.
• Faulty ADS sensor: One of the ADS sensors may be faulty. This can cause the ACM to misinterpret the sensor data and set a DTC code.
• Faulty ACM: The ACM itself may be faulty. This can cause the ACM to misinterpret the sensor data or to send incorrect signals to the ADS system.

What are the symptoms of these DTC codes?

The symptoms of DTC codes B0035 and B0036 can vary depending on the specific cause of the problem. However, some common symptoms include:

1. Airbag warning light illuminated: This is the vehicle's way of signaling that there is a problem with the airbag system.
2. Airbag system may not deploy in the event of a collision: This is a serious safety hazard.
3. Other electrical problems: The short circuit or open circuit in the ADS circuit can also cause other electrical problems in the vehicle, such as lights flickering or electrical components not working properly.

How to diagnose these DTC codes?

If you are experiencing any of the symptoms listed above, it is important to have your vehicle diagnosed by a qualified automotive technician. The technician will use a scan tool to retrieve the DTC codes and then perform a thorough visual inspection of the ADS system.

To diagnose DTC codes B0035 and B0036, the technician may perform the following tests:

1. Check the ADS module for damage or corrosion
2. Test the ADS wiring harness for resistance and continuity
3. Check for any short circuits or open circuits in the ADS wiring harness
4. Test the PCM for proper operation

How to repair these DTC codes?

Once the cause of the DTC code has been diagnosed, the technician can recommend the appropriate repairs. If the ADS module is faulty, it will need to be replaced. If there is a short circuit or open circuit in the ADS wiring harness, the short or open circuit must be repaired. If the PCM is faulty, it may need to be replaced.

How to prevent these DTC codes from happening again?

There are a few things you can do to help prevent DTC codes B0035 and B0036 from happening again:

• Have your vehicle serviced regularly
• Use high-quality electrical components
• Avoid driving through water or puddles

By following these tips, you can help keep your vehicle running smoothly and reduce the chances of developing DTC codes.

Additional topics:

• Safety: It is important to have DTC codes B0035 and B0036 repaired as soon as possible. If the ADS system is not working properly, it may not deploy the airbags in the event of a collision. This could put you and your passengers at risk of serious injury or death.
• Cost: The cost of repairing DTC codes B0035 and B0036 can vary depending on the specific cause of the problem. However, it is important to remember that safety is worth the investment.

If you are experiencing any of the symptoms listed above, it is important to have your vehicle diagnosed by a qualified automotive technician as soon as possible.
