DIAGNOSIS AND TESTING (Continued)
ROUTINE 1: VEHICLE DOES NOT START/VEHICLE QUITS WHILE DRIVING (LEAD ACID VEHICLES)
• 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 Traction Battery High Voltage Service Cord to traction battery
support tray in-line C1935F and in-line C1935M.
• Connect Traction Battery Low Voltage Service Cord to traction battery
support tray in-line C1939F and in-line C1939M.
• With key OFF, disconnect the battery temperature sensor in question and
one of the other temperature sensors.
• Connect jumper wires between the connector for the temperature sensor
in question and the known good temperature sensor that was
disconnected.
• With key ON, monitor BCM PIDs TMPSEN1, TMPSEN2, TMPSEN3,
and TMPSEN4.
• Does the TMPSEN PID that indicated less than -20°C (-4°F) still
indicate -20°C (-4°F)?
1-10 CHECK STATUS OF KEY START SIGNAL TO TRACTION
INVERTER MODULE (TIM)
• With key ON, monitor TIM PID IGN S.
• Turn the ignition key to the START position.
• Does the IGN S PID indicate YES when the ignition key is turned
to the START position?
1-11 CHECK FUSE (HOT IN START) TO TIM
• Check 7.5A fuse 24, 10A fuse 9 and 7.5A fuse 11 in the I/P fuse panel.
• Is the fuse OK?
1-12 CHECK KEY START SIGNAL TO TIM
• Connect 104-Pin Breakout Box (BOB) to TIM C4998, C4999 using the
BCM/TIM BOB Adapter Cable & Overlay; leave the TIM disconnected.
• Connect a multimeter between BOB pins B8 and A29.
• Turn the ignition key to the START position.
• Is the voltage greater than 10 volts when the ignition key is turned to
the key START position?
1-13 CHECK EMERGENCY POWER OFF (EPO) STATUS TO TIM
• With key ON, monitor TIM PID EMG PO.
• Does the EMG PO PID indicate ENABLE?
1-14 CHECK EPO SIGNAL TO TIM
• Connect 104-Pin Breakout Box (BOB) to TIM and TIM C4998, C4999
using the BCM/TIM BOB Adapter Cable & Overlay.
• With key ON, monitor TIM PID EMG PO.
• Connect a jumper wire between BOB pins A19 and A35.
• Does the EMG PO PID indicate DISABLE?
1-15 CHECK CIRCUIT 3997 (DG) (OUTSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
• With key OFF, disconnect BOB from TIM and TIM C4998, C4999.

Powertrain Diagnostic Routines Identification
TEST STEP ACTION TO TAKE
Yes = REPLACE the BCM.
REFER to Section
414-03A.
No = REPLACE the battery
temperature sensor in
question.
Yes = GO to 1-13.
GO to 1-11.
No =
GO to 1-12.
Yes =
No = REPLACE the fuse. If the
fuse fails again,
CHECK/REPAIR for a short
to ground, or TIM internal
failure.
Yes = REPLACE the TIM. REFER
to Section 303-14.
No = REPAIR the W/BK wire
between pin 8 on TIM
C4999 and the I/P fuse
panel.
Yes = GO to 1-14.
GO to 1-19.
No =
Yes = GO to 1-15.
No = GO to 1-17.
GO to 1-16.
Yes =
