Kia Sedona (2008 year). Manual - part 143

PANIC 



If RKE PANIC signal is received, Siren output and hazard lamp operate for 27 seconds and the system 
return to the previous state as soon as the PANIC function finishes.  



The PANIC function will be stopped if any RKE signal is received during PANIC activation.  



If Key reminder switch is ON during PANIC function is operating, PANIC is stopped immediately.  



If the system goes to ALARM mode during PANIC function is operating, PANIC is stopped immediately 
and then ALARM function should be activated.  



During ALARM state; 

If RKE PANIC signal is received, ALARM mode is maintained and PANIC function should be ignored. 
ALARM has higher priority than PANIC function. 



During AFTER_ALARM state; 

If RKE PANIC signal is received, AFTR_ALARM mode is maintained and PANIC function should be 
activated. 

SAFE & RESCUE MODE 

The goal of those modes is to be able to cope with failures that may happen on some of the most critical 
functionalities (for the driver security) of the system. 

SAFE MODE 

The safe mode is entered in case of system problems such as: 



Incoherent inputs on monitored signals. In this case, safe mode is the debouncing time before the inputs 
are considered INVALID. Note that today, we have no way to detect if the rain/light sensor is in working 
operation or not. It means that a driver action will be required in case of failure of this sensor;  



Loss of the CAN frame containing the monitored signal:  



Loss of the CAN network: CAN goes to BUS OFF state, safe mode is the time necessary for detecting the 
BUS OFF state.  

In all cases, the action in safe mode is to maintain the previous state of the system (for lighting and wiping). The 
list of monitored signals is the same as in rescue mode 

EXITING SAFE MODE 

The software safe mode is exited and the module goes back to the normal mode when: 



On IPM, hardware inputs return to a coherent state;  



The lost CAN signal comes back while timeout has not elapsed;  



The CAN network returns to a normal state without reaching BUS OFF state.

Software safe mode is also exited when the software rescue mode is entered (problem does not disappear).

Hardware safe mode is exited and the module goes back to normal mode if the internal problem disappears 
(watchdog is properly triggered again). If the problem stays, hardware safe mode is exited to enter hardware 
rescue mode. 

RESCUE MODES 

The rescue mode consists in activating some safety functions when IGN2 = ON: 



Switch on the low beams (FAM), park lamps (FAM), tail lamps (RAM) and cluster backlighting (IPM);  



Unlock of all the doors when the rescue mode is entered with IGN2 = ON  



Front wipers do not need to be turned on by software in rescue mode because wipers can be turned on by 
manually setting the MF switch to low speed. The FAM software must keep the same state as before 
entering the rescue mode.  



When IGN2 = OFF, low beams, park/tail lamps and cluster backlighting are turned off.  

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 InhibitSwSts, to detect loss of CAN connection with FAM.  



Timeout on CAN signal StopLpErrorSts, 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 ParkTailHeadLpCtrl 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 FWiperC-trl is sent with INVALID value and rescue 
mode is entered.  



CAN is in Bus Off state  

RAM 



Timeout on CAN signal InhibitSwSts, to detect loss of CAN connection with FAM.  



Timeout on CAN signal ParkTailHeadLpCtrl or FWiperCtrl, to detect loss of CAN connection with IPM. 



ParkTailHeadLpCtrl = INVALID or unknown value  



FWiperCtrl = INVALID or unknown value  



CAN is in Bus Off state  

FAM 



Timeout on CAN signal StopLpErrorSts, to detect loss of CAN connection with RAM



Timeout on CAN signal ParkTailHeadLpCtrl or FWiperCtrl, to detect loss of CAN connection with IPM  



ParkTailHeadLpCtrl = INVALID or unknown value  



FWiperCtrl = INVALID or unknown value  



CAN is in Bus Off state  

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

TROUBLE DIAGNOSTICS WHEN USING DIAGNOSIS TOOL 

1. The diagnosis tool supports quick diagnosis of supported body electrical systems through input/output 

monitoring, and actuation testing.  

2. To diagnose the BCM function, select the menu of model and body control module.
