Details of the c1870 OBD Code
Code C1870 relates to a fault in the suspension system of the vehicle.
OBD code C1870 means that a suspension movement sensor input signal is out of range.
This code is triggered by the Electronic Suspension Control Module (ESCM) based on abnormal readings from the suspension movement sensor.
The suspension movement sensor is responsible for monitoring the movement and position of the vehicle’s suspension components.
When the sensor detects values that are outside the expected range, it triggers the C1870 fault code.
Mechanic’s Tech Notes
Code C1870 relates to a fault in the suspension system’s calibration.
OBDII code C1870 relates to a fault in the suspension system.
To diagnose this, use a scan tool to check for any other related codes and ensure the TCM (Transmission Control Module) is communicating properly over the CAN network.
Additionally, inspect the wiring harness and connectors for any damage or corrosion.
Use a voltmeter to test the TCM’s power and ground connections.
If everything checks out, consider reprogramming the TCM as a potential fix.
Remember to clear the code after any repairs are made to see if it returns.
