Kia Sedona (2008 year). Instruction — 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.

4. Dose left outside mirror motor work properly?

YES

Go to step 2.

NO

Substitute with a known-good left outside mirror and check for proper operation.

If the problem is corrected, replace left outside mirror and then go to "VERIFICATION OF
VEHICLE REPAIR" procedure.

2. Check Mirror folding switch

1. Ignition "ON" & engine "OFF"

2. Connect Mirror folding Motor.

3. check if mirror folding motor work properly while operating mirror folding switch.

4. Dose left mirror folding motor work properly?

YES

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.

NO
