DIAGNOSIS AND TESTING (Continued)
ROUTINE 8: VEHICLE DOES NOT CHARGE (LEAD ACID VEHICLES)
• With key OFF, disconnect traction battery support tray in-line C1939 and Yes =
connect 104-Pin Breakout Box (BOB) to in-line C1939M using Traction
Battery Low Voltage Service Cord; do not connect Traction Battery Low
Voltage Service Cord to in-line C1939F.
• With key OFF, disconnect traction battery charger C1993.
• With key OFF, measure the resistance of the O/R wire between pin 7 on
traction battery charger C1993 and BOB pin 56.
• Is the resistance less than 5 ohms?
8-25 CHECK CIRCUIT 3009 (O/R) (OUTSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR SHORT TO GROUND
• With key OFF, measure the resistance between BOB pins 56 and ground
(BOB pin 65).
• Is the resistance greater than 10,000 ohms?
8-26 CHECK CIRCUIT 3009 (O/R) (INSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
• Disconnect BOB from in-line C1939M, remove the traction battery, and
connect Traction Battery High-Voltage Lockout and Diagnostic Tool to
the traction battery high-voltage two-pin C3994M.
WARNING: The traction battery contains high-voltage
components and wiring. High-voltage insulated safety gloves and face
shield must be worn when carrying out the following steps. Failure to
follow this warning may result in severe personal injury or death.
• Connect BOB to traction battery support tray in-line C1939F using
Traction Battery Low Voltage Service Cord; do not connect Traction
Battery Low Voltage Service Cord to in-line C1939M.
• With key OFF, disconnect BCM C1986.
• Measure the resistance of the O/R wire between pin 6 on BCM C1986
and BOB pin 56.
• Is the resistance less than 5 ohms?
8-27 CHECK CIRCUIT 3009 (O/R) (INSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR SHORT TO GROUND
• With key OFF, measure the resistance between BOB pins 56 and ground
(BOB pin 65).
• Is the resistance greater than 10,000 ohms?
8-28 CHECK CHARGER CORD INPUT STATUS
NOTE: Verify the power control station (PCS) charger cord is connected
to the charger inlet before carrying out this test step.
• With key OFF, connect the PCS to the charger inlet connector and
monitor BCM PID CHGCORD.
• Does the CHGCORD PID indicate IN?
8-29 CHECK CHARGER INLET
• With key OFF, disconnect in-line C1969 (located on the chassis next to
the right headlamp inside the underhood compartment).
• With key OFF, connect the PCS to the charger inlet connector and
measure the resistance between the Y wire and BK wire on in-line
C1969F.
• Is the resistance less than 5 ohms?
8-30 CHECK CIRCUIT 3404 (Y) (OUTSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
