B2850 PDM(POWER DELIVERY MODULE)

Description

INFOID:0000000010121264

Two temperature sensors are integrated in the PDM (Power Delivery Module), and monitor the charging circuit

temperature and control circuit board temperature.

The PDM (Power Delivery Module) also detects sensor accuracy malfunctions by comparing the signals from

each sensor.

TYPE A : Diagnosis Procedure

INFOID:0000000010121268

1.

CHECK QUICK CHARGE RELAY OPERATION

With CONSULT

1. Turn power switch ON.

2. Select “Q/CHG RELAY +” in “ACTIVE TEST” mode of “CHARGER/PD MODULE” using CONSULT. 

3. Switch the quick charge relay between ON and OFF to check operating noise.

NOTE:

If operating noise is hard to hear, use a sound scope to check noise.

4. Check “Q/CHG RELAY 

−” in same manner.

Can operating sound be heard?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

PERFORM DTC CONFIRMATION PROCEDURE AGAIN

With CONSULT

2. Turn power switch OFF.

3. Perform DTC confirmation procedure again. Refer to 

VC-81, "DTC Logic"

.

Is the DTC detected again?

YES

>> Replace PDM (Power delivery module). Refer to  

VC-112, "Removal and Installation"

.

NO

>> INSPECTION END

3.

4. Select “F/S CHG RLY” in “ACTIVE TEST” mode of “EV/HEV”

using CONSULT.

5. Turn ON the F/S CHG relay.

6. Check the voltage between PDM (Power Delivery Module) har-

ness connector and ground.

Is the inspection result normal?

YES

>> Replace PDM (Power Delivery Module). Refer to 

VC-112, "Removal and Installation"

.

NO

>> GO TO 5

5.

CHECK F/S CHG RELAY SIGNAL CIRCUIT

1. Turn power switch OFF.

2. Remove F/S CHG relay.

3. Check the continuity between PDM (Power Delivery Module) harness connector and F/S CHG relay har-

ness connector.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Repair or replace error-detected parts.

6.
