Entering Rescue Modes

Rescue mode is entered when some important CAN signal or hardware input are not available. Rescue mode is entered when one of the following conditions is true:

IPM

• Timeout on CAN signal Inhibit Sw Sts, to detect loss of CAN connection with FAM.
• Timeout on CAN signal Stop Lp Error Sts, to detect loss of CAN connection with RAM.
• MF Light Switch information is invalid: when the signals coming from MF Light Switch are not coherent for more than 2 s, CAN signal Park Tail Head Lp CTRL is sent with INVALID value and rescue mode is entered.
• Front Wiper MF Switch information is invalid: when the signals coming from Front Wiper MF Switch are not coherent for more than 2 s, CAN signal F Wiper CTRL is sent with INVALID value and rescue mode is entered.
• CAN is in Bus Off state

RAM

• Timeout on CAN signal Inhibit Sw Sts, to detect loss of CAN connection with FAM.
• Timeout on CAN signal Park Tail Head Lp CTRL or F Wiper CTRL, to detect loss of CAN connection with IPM.
• Park Tail Head Lp CTRL = INVALID or unknown value
• F Wiper CTRL = INVALID or unknown value
• CAN is in Bus Off state

FAM

• Timeout on CAN signal Stop Lp Error Sts, to detect loss of CAN connection with RAM
• Timeout on CAN signal Park Tail Head Lp CTRL or F Wiper CTRL, to detect loss of CAN connection with IPM
• Park Tail Head Lp CTRL = INVALID or unknown value
• F Wiper CTRL = INVALID or unknown value
• CAN is in Bus Off state

For all CAN signals, timeout duration is 2.5 times signal periodicity.
