Kia Sedona (2008 year). Manual - part 155

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

4. Is the DTC B1605 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 B1102. 

SIGNAL CIRCUIT INSPECTION 

1. Check CAN high communication circuit 

1. Ignition "ON" and Engine "OFF".  

2. Connect scan tool and select VEHICLE SCOPEMETER function.  

3. Measure waveform between terminal "BCM-IF-30" of IPM and chassis ground. 

Specification: CAN communication waveform is displayed

4. Is the measured waveform within specifications? 

The existence of CAN communication waveform itself shows there's no trouble in CAN 
communication circuit. If there's any short in harness, no signal is detected.

YES  

Go to step 2. 

NO  

Check for short circuit in signal harness. Repair as necessary and go to "VERIFICATION 
VEHICLE REPAIR" procedure. 

2. Check CAN low communication circuit 

1. Ignition "ON" and Engine "OFF".  

2. Connect scan tool and select VEHICLE SCOPEMETER function.  

3. Measure waveform between terminal "BCM-IF-39" of BCM ECU and chassis ground. 

Specification: CAN communication waveform is displayed

4. Is the measured waveform within specifications? 

The existence of CAN communication waveform itself shows there's no trouble in CAN 
communication circuit. If there's any short in harness, no signal is detected 

YES  

Go to "COMPONENT INSPECTION" procedure. 

NO  

Check for short circuit in signal harness. Repair as necessary and go to "VERIFICATION 
VEHICLE REPAIR" procedure.

4. Is the measured voltage within specifications? 

YES  

Go to "COMPONENT INSPECTION" procedure. 

NO  

Check for open or short in power harness. Repair as necessary and go to "VERIFICATION OF 
VEHICLE REPAIR" procedure. 

COMPONENT INSPECTION 

1. Check DDM 

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

2. Ignition "ON" & engine "OFF".  

3. Substitute with a known-good DDM and Check if the DTC is erased.  

4. Is the DTC erased? 

YES

2. Check IPM 

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

2. Ignition "ON" & engine "OFF".  

3. Substitute with a known-good IPM and Check if the DTC is erased.  

4. Is the DTC erased? 

YES  

Substitute with a known-good IPM and check for proper operation. 

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

NO  

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