DIAGNOSIS AND TESTING (Continued)
ROUTINE 1: VEHICLE DOES NOT START/VEHICLE QUITS WHILE DRIVING (LEAD ACID VEHICLES)
TEST STEP ACTION TO TAKE
•
Remove the traction battery and connect Traction Battery High-Voltage Yes = REPLACE the BCM.
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin REFER to Section
C3994M. 414-03A .
No = REPLACE the battery
WARNING: The traction battery contains high-voltage
temperature sensor in
components and wiring. High-voltage insulated safety gloves and face
question.
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. Yes = GO to 1-13.
•
Turn the ignition key to the START position. No = GO to 1-11.
•
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. Yes = GO to 1-12.
•
Is the fuse OK?
No = REPLACE the fuse. If the
fuse fails again,
CHECK/REPAIR for a short
to ground, or TIM internal
failure.
1-12 CHECK KEY START SIGNAL TO TIM
•
Connect 104-Pin Breakout Box (BOB) to TIM C4998, C4999 using the Yes = REPLACE the TIM. REFER
BCM/TIM BOB Adapter Cable & Overlay; leave the TIM disconnected. to Section 303-14 .
•
Connect a multimeter between BOB pins B8 and A29. No = REPAIR the W/BK wire
•
Turn the ignition key to the START position. between pin 8 on TIM
•
Is the voltage greater than 10 volts when the ignition key is turned to
C4999 and the I/P fuse
the key START position?
panel.
1-13 CHECK EMERGENCY POWER OFF (EPO) STATUS TO TIM
•
With key ON, monitor TIM PID EMG PO. Yes = GO to 1-14.
•
Does the EMG PO PID indicate ENABLE?
No = GO to 1-19.
1-14 CHECK EPO SIGNAL TO TIM
•
Connect 104-Pin Breakout Box (BOB) to TIM and TIM C4998, C4999 Yes = GO to 1-15.
using the BCM/TIM BOB Adapter Cable & Overlay.
•
With key ON, monitor TIM PID EMG PO. No = GO to 1-17.
•
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. Yes = GO to 1-16.
