Kia Sedona (2008 year). Manual - part 192

4. Is the DTC B2521 present? 

YES  

Go to TERMINAL AND CONNECTOR INSPECTION procedure. 

NO  

Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was repaired and 
ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, 
corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to 
"VERIFICATION OF VEHICLE REPAIR" procedure. 

TERMINAL AND CONNECTOR INSPECTION 

Refer to DTC B2119. 

COMPONENT INSPECTION 

1. Check FUSE 

1. Ignition "ON" & engine "OFF".  

2. Disconnect stop lamp fuse of FAM and check its state.  

3. Is fuse OK? 

YES  

Go to step 2. 

NO  

Replacing the fuse with `stop lamp fuse for test', if normal operating condition is confirmed, 
Replace `stop lamp fuse for test' with `new stop lamp' and go to "VERIFICATION OF 
VEHICLE REPAIR". 

2. Check FAM 

1. Connect scan tool to Data Link Connector (DLC).  

2. Ignition "ON" & engine "OFF", FAM: ON.  

3. Measure the voltage between stop lamp power circuit of FAM (BCM-FE-34) and chassis ground. 

Specification: 12V

4. Is the measured voltage within the specification? 

YES  

Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, 
or damage. 

Repair or replace if necessary and then go to "VERIFICATION OF VEHICLE REPAIR" 
procedure. 

NO  

Replacing the FAM with `FAM for test', if normal operating condition is confirmed, Replace `FAM 
for test' with `new FAM' and go to "VERIFICATION OF VEHICLE REPAIR".

GENERAL DESCRIPTION 

RAM is a component of BCM that consists of DDM, ADM, IPM, FAM, IMS and cluster module. Each part of 
BCM is connected to one another through CAN communication line for efficient communication. Those 
modules control front/rear, driver/passenger seat, cluster with electrical signal and they share information with 
other modules. RAM (Rear Area Module) set up at rear-left of passenger room controls various rear lamps (tail 
lamp, rear turn signal lamp, backup lamp, stop lamp, cabin lamp), window (sliding door power window, quarter 
glass, rear defogger), rear wiper and oil cap door, the power of stop lamp is supplied from the power line 
through FAM-->stop lamp-->RAM-->lamp in sequence. Controlling stop lamp is performed at FAM and RAM. 
FAM transfers power from "HOT AT ALL TIMES power circuit" to stop lamp switch and via RAM, this power 
is supplied to stop lamp. Furthermore, RAM senses stop temp circuit error as well. 

DTC DESCRIPTION 

B2524 is set when open in RAM or stop lamp circuit is detected. 

DTC DETECTING CONDITION 

Refer to DTC B2115. 

MONITOR DTC STATUS 

1. Connect scan tool to Data Link Connector (DLC).  

2. Ignition "ON" & engine "OFF".  

3. Select "Diagnostic Trouble Codes (DTCs)" mode and monitor "DTC Status" parameter.

4. Is the DTC B2524 set? 

YES  

Go to TERMINAL AND CONNECTOR INSPECTION. 

NO  

Fault is intermittent caused by poor contact in the sensor's and/or ECM's connector or was repaired and 
ECM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, 
corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to

TERMINAL AND CONNECTOR INSPECTION 

Refer to DTC B2441. 

POWER SUPPLY CIRCUIT INSPECTION 

1. Check open in power circuit 

1. Ignition "ON" & engine "OFF"  

2. Measure the resistance between stop lamp power circuit connector terminal at RAM side (BEC-

RF1-33,43, BEC-RR-14) and stop lamp (F18,F19-2,R03-1). 

Specification: 0 ohms
