DIAGNOSIS AND TESTING (Continued)
Pinpoint Tests
Special Tool(s)
104-Pin Breakout Box (BOB) 418-049 (014-00950) or
equivalent
BCM/TIM Breakout Box (BOB) Adapter Cable
418-F212
BCM/TIM Breakout Box (BOB) Overlay 418-F220

PINPOINT TEST A: DTC B1676 BATTERY PACK VOLTAGE OUT OF RANGE
A1 CHECK FOR INTERFACE ADAPTER ASSEMBLY (IAA)
MODULE DIAGNOSTIC TROUBLE CODES (DTCs)
NOTE: Make sure low voltage TIM fuse(s) #9 (10A), #11 (7.5A), and #24
(7.5A) are good before performing test A1. If fuse(s) are OK, proceed with
A1, if not, install new fuse(s) and perform test A1.
NOTE:
Using High-Voltage Insulated Safety Gloves and Face Shield, disconnect
and check the traction battery high-voltage two-pin C3994 for damage
before carrying out the following test steps. Repair as necessary. If OK,
reconnect and verify the connection is secure.
• Carry out the on-demand self-test for the IAA module.
• Do IAA module DTCs C1862 Contactor Circuit Failure and U2015
Signal Link Fault (Non SCP) occur?
A2 CHECK GROUND TO CONTACTOR BOX
• With key OFF, disconnect traction battery support tray in-line C1939 and Yes =
connect 104-Pin Breakout Box (BOB) to traction battery support tray
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, measure the resistance between BOB pin 65 and ground.
• Is the resistance less than 5 ohms?
A3 CHECK CIRCUIT 57 (BK) FOR OPEN
• Disconnect the BOB from in-line C1939M and remove the traction
battery.
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.
• With key OFF, disconnect contactor box C1982 and measure the
resistance between pin 8 (BK wire) on contactor box C1982 and BOB
pin 65.
• Is the resistance less than 5 ohms?
A4 CHECK STATUS OF HIGH-VOLTAGE POWER TO TIM
• With key ON, monitor TIM PID BAT PV.
• Turn the ignition key to the START position.
• Does the BAT PV PID indicate between 50 and 385 volts?
