414-03B-73 414-03B-73 High Voltage/Traction Battery — Nickel Metal Hydride
DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST B: BATTERY PACK/MODULE(S) VOLTAGE OUT OF RANGE
TEST STEP ACTION TO TAKE
•
Does DTC C1864 Battery Module Fault occur?
No = GO to B2.
If DTC B1676 Battery Pack
Voltage Out of Range
occurs, GO to B8.
B2 CARRY OUT THE BATTERY MODULE DIAGNOSTIC TEST
•
With key ON, carry out the Battery Module Diagnostic Test. Refer to the Yes = If the B integer value is 1 or
procedure in Traction Battery System. 2, GO to B7.
If the Battery Module
Diagnostic Test integer
value is 4 or 5, GO to B3.
If the Battery Module
Diagnostic Test integer
value is 3, REFER to the
Lead-Acid Traction Battery,
Battery Module Diagnostic
Test Integer Values Chart to
determine the required
action.
•
Does the Battery Module Diagnostic Test Function Test indicate to
No = System OK.
replace any battery modules or to correct any other concerns?
B3 CHECK BATTERY MODULE FAULT STATUS
•
With key ON, monitor BCM PIDs BTM 1FT thru BTM25FT. Yes = GO to B4.
•
Do any of the battery module fault PIDs indicate YES?
No = GO to B7.
B4 CHECK VOLTAGE SENSE LINE CIRCUIT BETWEEN BCM AND
IN-LINE CONNECTOR FOR OPEN
•
Remove the traction battery and connect Traction Battery High-Voltage Yes = GO to B5.
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin
C3994M.
No = REPLACE high-voltage
harness (10B694). GO to
B6.
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 high-voltage C1865, C1866 and the
appropriate in-line connector for the battery module(s) in question.
NOTE: If a single battery module fault PID (with the exception of
BTM 1FT and BTM25FT) indicates YES, check the battery module in
question for reverse cable polarity. Reinstall (correctly) if necessary. If the
cable polarity is OK, GO to B7.
•
Measure the resistance of the wire between the BCM high-voltage
connector and in-line connector for the indicated battery module fault(s).
Use the following information:
Battery Module Faults
— 1: circuit 3089 (LB/W) between in-line C1750M (label A) and pin 4
on BCM C1865
— 1, 2: circuit 3072 (PK/Y) between in-line C1752M (label C) and pin
10 on BCM C1865
— 2, 3: circuit 3073 (R/W) between in-line C1751M (label B) and pin
16 on BCM C1865
