DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST J: CHARGER OVER CURRENT FAULT
J1 CHECK CONTACTOR BOX AUXILIARY CURRENT SENSOR
FOR IN-RANGE FAILURE
• With key ON, monitor BCM PID AUX CNT.
• Turn the A/C on and turn the steering wheel back and forth.
• Does the amperage for the AUX CNT PID increase and decrease?
J2 CHECK AUXILIARY CURRENT SENSOR VOLTAGE STATUS
• 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.
• With key OFF, disconnect contactor box C1982.
• With key ON, monitor BCM PID AUX SEN.
• Does the AUX SEN PID indicate greater then 1 volt?
PINPOINT TEST K: CHARGER OVER VOLTAGE FAULT
K1 CHECK TRACTION BATTERY POSITIVE (+) SENSE LINE
CIRCUIT BETWEEN IN-LINE C1885F AND BATTERY MODULE 25
FOR SHORTED RESISTOR
• 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.
• With key OFF, disconnect in-line C1885 (label W) and measure the
resistance between the LB wire on in-line C1885F and battery module 25
positive (+) post.
• Is the resistance between 28,000 and 34,000 ohms?
K2 CHECK TRACTION BATTERY NEGATIVE (-) SENSE LINE
CIRCUIT BETWEEN IN-LINE C1882F AND BATTERY MODULE 1
FOR OPEN
• With key OFF, disconnect in-line C1882 (label R) and measure the
resistance between the PK/BK wire on in-line C1882F and battery
module 1 positive (+) post.
• Is the resistance between 28,000 and 34,000 ohms?
PINPOINT TEST L: CHARGER OVER AMP-HOURS FAULT
L1 CHECK STATUS OF TRACTION BATTERY MODULES BY
CARRYING OUT THE BATTERY MODULE DIAGNOSTIC TEST
• With key ON, carry out the Battery Module Diagnostic Test. Refer to the Yes =
procedure in Traction Battery System.
