U0170 RAM Code - Lost Communication With Up-Front Left Satellite Acceleration Sensor
Quick Answer
The impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the ORC with periodic updates. Common causes include Faulty Left Front Impact Sensor, Left Front Impact Sensor harness is open or shorted, Left Front Impact Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
Frequently Asked Questions about U0170 RAM Code
What does the OBDII code U0170 mean for my RAM vehicle?
U0170 indicates that there is a lost communication issue with the up-front left satellite acceleration sensor, which affects the vehicle's ability to read acceleration data accurately.
What are the common symptoms of a U0170 code?
Common symptoms include warning lights on the dashboard, issues with traction control or stability control systems, and possible erratic handling or performance issues.
What could cause the U0170 code to trigger?
The code can be triggered by a faulty satellite acceleration sensor, damaged wiring or connectors, or issues with the vehicle's main control module.
How can I diagnose the U0170 code?
Start by using an OBD-II scanner to confirm the code. Then, inspect the satellite acceleration sensor and its wiring for damage, corrosion, or loose connections. Testing the sensor's operation may also be necessary.
Is it safe to drive my RAM with a U0170 code?
While it might be safe to drive, you may experience handling issues or decreased stability. It's advisable to have the vehicle inspected and repaired to ensure optimal performance and safety.
Can I repair the U0170 code myself?
If you have automotive repair experience, you can check the wiring and connections or replace the sensor. However, if you're unsure, it's best to consult a professional mechanic.
What is the cost range for repairing a U0170 code?
Repair costs can vary widely depending on whether it’s just a wiring issue or if the satellite acceleration sensor needs to be replaced. Expect to pay anywhere from $100 to $500 or more, depending on labor and parts.
How does a faulty satellite acceleration sensor affect my vehicle?
A faulty satellite acceleration sensor can lead to poor vehicle stability, inaccurate traction control, and potentially unsafe driving conditions, especially in adverse weather.
Will clearing the U0170 code fix the problem permanently?
Clearing the code may temporarily remove the warning, but if the underlying issue (like a faulty sensor or wiring problem) is not addressed, the code will likely reappear.
