P18Bc Fault Code: Understanding The Description And Troubleshooting Tips
The P18BC fault code refers to the Internal Mode Switch ‘C’ Circuit Stuck Off Invalid Voltage Range.
This code is related to the Transmission Control Module (TCM) and indicates that the gear position selected by the vehicle operator is not being properly communicated to the TCM. The internal mode switch consists of 5 separate hall effect switches, each supplied with a 9V reference circuit and a signal circuit from the TCM.
These signal circuits have specific voltage ranges to indicate whether a particular gear selector position is on or off. When the TCM detects that the internal mode switch ‘C’ signal circuit has an invalid voltage range of 1.68 – 2.38V for 2.7 seconds, it sets the P18BC fault code. This means that the TCM is not receiving the correct voltage readings for the gear selector position, indicating a problem with the internal mode switch ‘C’ circuit.
To resolve this issue, the internal mode switch ‘C’ circuit needs to be inspected and repaired if necessary. This may involve checking the wiring connections, replacing faulty components, or recalibrating the switch. It is recommended to consult a professional mechanic or use a scan tool to diagnose and fix the problem accurately.
FAQ
