DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST A: DTC B2517 EMERGENCY POWER OFF SYSTEM FAULTED
• With key OFF, measure the voltage between BOB pin 47 and ground
(BOB pin 65).
• Is the voltage greater than 10 volts?
A15 CHECK TIM HIGH-VOLTAGE TWO-PIN CONNECTOR
INTERLOCK FOR OPEN
• With key OFF, measure the resistance between the interlock pins on TIM Yes =
high-voltage two-pin C3994F.
• Is the resistance less than 5 ohms?
A16 CHECK POWER TO CONTACTOR BOX
• Remove the traction battery and connect Traction Battery High-Voltage
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin
C3994M.
• Connect Traction Battery High-Voltage Service Cord to traction battery
support tray in-line C1935F and in-line C1935M.
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 Traction Battery Low-Voltage Service Cord to traction battery
support tray in-line C1939F and in-line C1939M.
• With key OFF, disconnect contactor box C1982 and measure the voltage
between pin 6 (Y wire) on contactor box C1982 and ground.
• Is the voltage greater than 10 volts?
PINPOINT TEST B: VEHICLE WILL NOT START (POWER RESET INDICATOR ILLUMINATED)
B1 CHECK FOR ACTIVATED INERTIA SWITCH
• Check the inertia switch.
• Is the inertia switch activated?
B2 CHECK INERTIA SWITCH
• With key OFF, disconnect inertia switch C249 and measure the
resistance between the LB/W wire terminal and W wire terminal on the
inertia switch with the inertia switch in the deactivated (depressed)
position.
• Is the resistance less than 5 ohms?
