Details of the c161f OBD Code
Code C161F relates to a malfunction in the ABS hydraulic pump motor circuit.
OBD code C161F means that there is an internal electronic failure in the ABS module.
This code is triggered by the ABS module itself when it detects a fault within its internal circuitry or components.
The ABS module is responsible for monitoring the wheel speed sensors and controlling the antilock braking system.
When the module detects an issue with its internal components, it will set code C161F to indicate a problem with its operation.
Mechanic’s Tech Notes
Code C161F indicates a malfunction in the ABS module communication circuit.
OBDII code C161F typically indicates a problem with the Transmission Control Module (TCM).
To diagnose this, start by checking the TCM’s power and ground using a multimeter.
Ensure the TCM responds over the Controller Area Network (CAN) network by using a scan tool.
If the TCM does not respond, reprogramming or reflashing it may be necessary.
Visually inspect the wiring harness and connectors for any damage, and check the connector pins for signs of being broken, bent, pushed out, or corroded.
This thorough inspection can help pinpoint the root cause of the issue.
