DTC P0D26: BATT. Charger System (Precharge)
DESCRIPTIONS OF MONITOR METHODS
On-board charger (OBC) capacitor voltage increases at the beginning of each charge cycle.
On-board charger (OBC) capacitor voltage is monitored in the following sequential stages.
From charge permission is received by OBC until the capacitor voltage increases to V1.
note
V1: 120 volts (100 volts input) or 240 volts (200 volts input)
MONITOR EXECUTION
Continuous
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
Battery charger control module (OBC) monitor
Sensor (The sensor below is determined to be normal)
Not applicable
DTC SET CONDITIONS
Logic Flow Chart
Check Conditions
Charge permission from PHEV-ECU is on.
Charger voltage command value is more than 0 volt.
Input voltage is 80 volts to 120 volts.
Judgment Criterion
Change of the charger capacitor voltage is less than 240 volts (200 volts input) or 120 volts (100 volts input) for 45 seconds.
OBD-II DRIVE CYCLE PATTERN
Refer to OBD-II Drive Cycle - Pattern 3
.
FAIL-SAFE AND BACKUP FUNCTION
The charge is stopped.
PROBABLE CAUSE
The on board charger/DC-DC converter is failed.
DIAGNOSIS
STEP 1. Test the OBD-II drive cycle.
(1)
Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 3
.
(2)
Check the DTC.
Is the DTC set?
Replace the on board charger/DC-DC converter (Refer to
). Then go to Step 2
.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions
).
STEP 2. Test the OBD-II drive cycle.
(1)
Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 3
.
(2)
Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The inspection is complete.
