DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST J: CHARGER OVER CURRENT FAULT
• 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 performing 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 than 1 volt?
PINPOINT TEST K: CHARGER OVER VOLTAGE FAULT
K1 CHECK TRACTION BATTERY POSITIVE (+) SENSE LINE
CIRCUIT BETWEEN IN-LINE C1885F AND BATTERY MODULE 39
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 performing 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 39
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 PIK/BK wire on in-line C1882F and battery
module 1 negative (-) post.
• Is the resistance between 28,000 and 34,000 ohms?
PINPOINT TEST M: CHARGER LINE CAPACITY FAULT
M1 VERIFY POWER CONTROL STATION (PCS) OPERATION
• Perform Power Control Station (PCS) Operation Verification Test. Refer
to Pinpoint Test S.
• Is the PCS OK?
M2 CHECK FOR CHARGING SYSTEM FAULT
