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 contactor box C1982 and measure the
resistance of the DG wire between pin 16 on contactor box C1982 and
BOB pin 24.
• Is the resistance less than 5 ohms?
2-18 CHECK CIRCUIT 3997 (DG) (OUTSIDE TRACTION BATTERY
SUPPORT TRAY) FOR SHORT TO GROUND
• With key OFF, disconnect BOB from TIM and TIM C4998, C4999.
• With key OFF, disconnect in-line C1939 on the traction battery support
tray and connect BOB to in-line C1939M using Traction Battery Low
Voltage Service Cord; do not connect Traction Battery Low Voltage
Service Cord to traction battery support tray in-line C1939F.
• With key OFF, measure the resistance between BOB pin 24 and ground
(BOB pin 65).
• Is the resistance greater than 10,000 ohms?
2-19 CHECK CIRCUIT 3997 (DG) (INSIDE OF TRACTION BATTERY
SUPPORT TRAY) FOR SHORT TO GROUND
• 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 contactor box C1982 and measure the
resistance BOB pin 24 and ground (BOB pin 65).
• Is the resistance greater than 10,000 ohms?
2-20 CHECK STATUS OF TIM OPERATING STATE
• With key ON, monitor TIM PID TIM OP.
• Does the TIM OP PID indicate 20 (shutdown)?
2-21 CHECK KEY RUN/START SIGNAL TO CONTACTOR BOX AT
TRACTION BATTERY SUPPORT TRAY
• With key OFF, disconnect in-line C1939 on the traction battery support
tray.
• Connect BOB to in-line C1939M using Traction Battery Low Voltage
Service Cord; do not connect Traction Battery Low Voltage Service Cord
to traction battery support tray in-line C1939F.
• With key ON, measure the voltage between BOB pin 21 and ground
(BOB pin 65).
• Is the voltage greater than 10 volts?
2-22 CHECK CIRCUIT 295 (LB/PK) (INSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
