What is CID 998 & How to Solve It?

What is CID 998:

cid 998 refers to a fault in the brake pedal position sensor. incorrect readings can impact brake light operation or regenerative braking systems.

‍

Why This Happens:

• worn or faulty brake pedal position sensor.
  
• misaligned brake pedal assembly.
  
• damaged wiring or connectors.
  
• debris obstructing sensor moement.
  
• ecm signal misread.
  
  

How to Fix It:

1. inspect the brake pedal assembly for proper movement.
   
2. test sensor voltage range during pedal operation.
   
3. repair or replace damaged wiring.
   
4. recalibrate ecm input for brake position.
   
5. replace sensor if malfunction persists.
   
   

How to Avoid It Before It Happens:

• inspect pedal sensors during brake maintenance.
  
• keep connectors clean and sealed.
  
• verify brake signal response via diagnostics.
  
• clue’s safety management tools monitor braking systems to ensure fleet safety compliance.
