DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST B: BATTERY PACK/MODULE(S) VOLTAGE OUT OF RANGE
TEST STEP ACTION TO TAKE
WARNING: The traction battery contains high-voltage
components and wiring. High-voltage insulated safety gloves and face
shield must be worn when performing 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 BCM high-voltage C1866.
•
With key OFF, disconnect in-line C1885 (label W) and measure the
resistance of the LB wire between pin 30 on BCM high-voltage C1866
and in-line C1885M.
•
Is the resistance less than 5 ohms?
B8 CHECK TRACTION BATTERY POSITIVE (+) SENSE LINE
CIRCUIT BETWEEN IN-LINE C1885F AND BATTERY MODULE 39
FOR OPEN
•
With key OFF, measure the resistance between the LB wire on in-line Yes = GO to B9.
C1885F and battery module 39 positive (+) post.
•
Is the resistance between 28,000 and 34,000 ohms?
No = REPLACE high-voltage
harness (14A280-WD).
B9 CHECK TRACTION BATTERY NEGATIVE (-) SENSE LINE
CIRCUIT 3215 (PK/BK) BETWEEN BCM AND IN-LINE C1882M FOR
OPEN
•
With key OFF, disconnect BCM high-voltage C1865 and in-line C1882 Yes = GO to B10.
(label R).
•
With key OFF, measure the resistance of the PK/BK wire between pin 1 No = REPLACE high-voltage
on BCM high-voltage C1865 and in-line C1882M. harness (10B694).
•
Is the resistance less than 5 ohms?
B10 CHECK TRACTION BATTERY NEGATIVE (-) SENSE LINE
CIRCUIT BETWEEN IN-LINE C1882F AND BATTERY MODULE 1
FOR OPEN
•
With key OFF, measure the resistance between the PK/BK wire on Yes = GO to B11.
in-line C1882F and battery module 1 negative (-) post.
•
Is the resistance between 28,000 and 34,000 ohms?
No = REPLACE high-voltage
harness (14A280-RF).
B11 CHECK FOR INTERMITTENT CONCERN(S)
•
With key OFF, reconnect in-line C1885 (label W), in-line C1882 (label Yes = REPLACE the BCM.
R), and BCM high-voltage C1865 and C1866.
•
Perform the on-demand self-test for the BCM. No = System OK.
•
Does DTC C1676 Battery Pack Voltage Out of Range occur?
PINPOINT TEST C: DTC C1864 BATTERY MODULE FAULT
TEST STEP ACTION TO TAKE
C1 CHECK STATUS OF BATTERY PACK
•
With key ON, monitor battery control module (BCM) PIDs REV BAT, Yes = If PID REV BAT indicates
12V BAT, and WRG BCM. YES, GO to C2.
If PID 12V BAT indicates
YES, GO to C4.
If PID WRG BCM
indicates YES, GO to C6.
•
Do any of the PIDs indicate YES?
No = System OK.
C2 CHECK BATTERY MODULE FAULT STATUS
