Kia Sedona (2008 year). Manual - part 186

DDM is a node of CAN communication system which consists of IPM. FAM, RAM, ADM, IMS. Main 
function of DDM is lock/unlock of door and window, adjusting position and fold/unfold of outside mirror. 
outside mirror folding control is performed by IPS. IPS is semiconductor which performs function of pre-
existing fuse and relay, IPS is located in DDM and send current to motor for mirror fold/unfold control 
according to switch signal. 

DTC DESCRIPTION 

The ECM sets DTC B2429 if there's short circuit in Mirror folding circuit harness. 

DTC DETECTING CONDITION 

DTC DETECTING CONDITION 

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 B2429 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 

1. Many malfunctions in the electrical system are caused by poor harness and terminals. 

Faults can also be caused by interference from other electrical systems, and mechanical or chemical 
damage.
