DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST A: DIGITAL TRANSMISSION RANGE (DTR) SENSOR CIRCUIT FAILURE
• Remove the traction battery and connect Traction Battery High-Voltage
Lockout and Diagnostic Tool to the traction battery high-voltage 2-pin
C3994M.
• Connect Traction Battery Low Voltage Service Cord to traction battery
support tray in-line C1939F and in-line C1939M.
• 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.
• With key OFF, disconnect BCM C1987.
• With key ON, measure the voltage between BOB pin B13 and ground
(BOB pin A29).
• Is the voltage greater than 0 volts?
A24 CHECK CIRCUIT 3503 (Y) (OUTSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR SHORT TO GROUND
• With key OFF, disconnect DTR sensor C4996 and traction battery
support tray in-line C1939.
• With key OFF, measure the resistance between BOB pin B13 and ground No =
(BOB pin A29).
• Is the resistance greater than 10,000 ohms?
A25 CHECK TR4 SIGNAL LINE TO BATTERY CONTROL MODULE
(BCM) (INSIDE OF TRACTION BATTERY SUPPORT TRAY) FOR
SHORT TO GROUND
• With key OFF, remove BOB from TIM C4998 and C4999.
• 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, measure the resistance between BOB pin 52 and ground
(BOB pin 65).
• Is the resistance greater than 10,000 ohms?
A26 CHECK CIRCUIT 3503 (Y) (INSIDE OF TRACTION BATTERY
SUPPORT TRAY) FOR SHORT TO GROUND
• Remove the traction battery and connect Traction Battery High-Voltage
Lockout and Diagnostic Tool to the traction battery high-voltage 2-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 C1987 and measure the resistance
between BOB pin 52 and ground (BOB pin 65).
• Is the resistance greater than 10,000 ohms?
