WARNING: This page is about a different car, the 2014 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
A failure is detected if one of the following conditions occurs:
- A failure in the SPI communication between the CPU and the watchdog ASIC (e.g. timeout of SPI message) is detected.
- The status value of the watchdog ASIC, which includes the watchdog error counter, is unequal to the expected value in the CPU software.
- The watchdog error counter is above the threshold to switch off the output stages.
- The number of safety relevant software modules monitored by the Program Flow Control is not as expected.
- A safety relevant software module monitored by the Program Flow Control has calculated an invalid checksum.
- The actual sequence of safety relevant software modules monitored by the Program Flow Control is not equal to the expected sequence.
