Details of the c1613 OBD Code
C1613 indicates a malfunction in the tire pressure monitoring system (TPMS) sensor.
OBD code C1613 means that a malfunction has been detected in the VIN information stored in the ABS control module.
This code is triggered by the ABS control module itself when it detects an inconsistency or error in the VIN data it has stored.
The VIN (Vehicle Identification Number) is a unique code assigned to each vehicle for identification purposes.
In this case, the ABS control module uses the VIN information for various functions related to vehicle safety systems.
Mechanic’s Tech Notes
Code C1613 relates to a malfunction in the tire pressure monitoring system (TPMS) sensor.
OBDII code C1613 relates to a problem with the transmission control module (TCM).
To diagnose this, check TCM power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
Visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
If everything looks good, consider reprogramming the TCM.
