414-03A-51 414-03A-51 High Voltage/Traction Battery
DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST B: DTC C1837 BATTERY HEATER CIRCUIT FAILURE
TEST STEP ACTION TO TAKE
B10 CHECK LOWER BATTERY HEATER FOR OPEN
•
Remove the traction battery and connect Traction Battery High-Voltage Yes = GO to B12.
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin
C3994M.
No = GO to B11.
WARNING: The traction battery contains high-voltage
components and wiring. High-voltage insulated safety gloves and face
shield must be worn when performing the following steps. Failure to
follow this warning may result in severe personal injury or death.
•
Disconnect contactor box C1864 and measure the resistance between pin
B (BK wire) and pin A (DB/W wire) on contactor box C1864.
•
Is the resistance between 135 and 165 ohms?
B11 CHECK CIRCUITS 1201 (DB/W) AND 57 (BK) FOR OPEN(S)
•
With key OFF, disconnect lower battery heater C1862 and measure the Yes = REPLACE the lower battery
resistance of the DB/W wire between pin A on contactor box C1864 and heater.
lower battery heater C1862.
•
With key OFF, disconnect lower battery heater C1863 and measure the No = REPLACE high-voltage
resistance of the BK wire between pin B on contactor box C1864 and harness 10B700.
lower battery heater C1863.
•
Are the resistances less than 5 ohms?
B12 CHECK BATTERY HEATER #2 CONTROL (CLOSE SIGNAL)
•
Connect Traction Battery High-Voltage Service Cord to traction battery Yes = GO to B14.
support tray in-line C1935F and in-line C1935M.
•
Connect Traction Battery Low-Voltage Service Cord to traction battery No = GO to B13.
support tray in-line C1939F and in-line C1939M.
•
Connect 104-Pin Breakout Box (BOB) to BCM and BCM C1986, C1987
using the BCM/TIM BOB Adapter Cable and Overlay.
•
Enter BCM active command mode BCM PACKETED COMMAND, set
the active command BAT HTR 2 to ENABLE, and measure the voltage
between BOB pin A3 and ground (BOB pin A33).
•
Is the voltage greater than 10 volts?
B13 CHECK CIRCUIT 3000 (P) FOR SHORT TO GROUND
•
With key OFF, disconnect BOB from BCM; leave BOB connected to Yes = REPLACE the BCM.
BCM C1986 and C1987.
•
With key OFF, disconnect contactor box C1982 and measure the No = REPAIR the P wire.
resistance between BOB pin A3 and ground (BOB pin A33).
•
Is the resistance greater than 10,000 ohms?
B14 CHECK CIRCUIT 3000 (P) FOR OPEN
•
With key OFF, disconnect contactor box C1982 and measure the Yes = REPLACE the contactor
resistance of the P wire between pin 10 on contactor box C1982 and box.
BOB pin A3.
•
Is the resistance less than 5 ohms?
No = REPAIR the P wire.
PINPOINT TEST C: DTC C1838 CHARGER SYSTEM FAULT
TEST STEP ACTION TO TAKE
C1 CHECK FOR CHARGING SYSTEM FAULT
NOTE: Record all DTCs from the BCM. including PREV_OP State code
Yes = GO to C2.
then clear the DTCs from the battery control module (BCM) continuous
memory before connecting the vehicle to a power control station (PCS).
The vehicle may need to be left on charge for up to five minutes to set a
charging system fault (DTC C1838).
•
Connect the vehicle to the PCS and press the START button to begin
charging.
