Code B10D9 Description

The Passive Anti-Theft System (PATS) transceiver receives voltage from the Smart Junction Box (SJB). The PATS transceiver and the Instrument Panel Cluster (IPC) communicate on dedicated transmit and receive circuits. The IPC compares the key code stored in memory and sends a signal to the Powertrain Control Module (PCM) to enable the starter and the fuel injectors if the key code is correct. The OBDII code set when the PATS transceiver signal is not received by the IPC. This Diagnostic Trouble Code (DTC) can be caused by circuits between the PATS transceiver and the IPC. This can also be caused by using the incorrect PATS transceiver part number.
