High Voltage/Traction Battery — Nickel Metal Hydride
DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST N: CHARGER MODE FEEDBACK FAULT
TEST STEP
ACTION TO TAKE
No =
REPAIR the BR/Y wire.
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.
•
Connect 104-Pin Breakout Box (BOB) to traction battery support tray
in-line C1939F using Traction Battery Low-Voltage Service Cord; do not
connect Traction Battery Low-Voltage Service Cord to in-line C1939M.
•
With key OFF, disconnect BCM C1986 and measure the resistance of the
BR/Y wire between pin 7 on BCM C1986 and BOB pin 49.
•
Is the resistance less than 5 ohms?
N10 CHECK CIRCUIT 3992 (BR/Y) (INSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR SHORT TO GROUND
•
With key OFF, measure the resistance between BOB pin 49 and ground
Yes =
REPLACE the traction
(BOB pin 65).
battery charger.
•
Is the resistance greater than 10,000 ohms?
No =
REPAIR the BR/Y wire.
PINPOINT TEST P: IOM TO BCM DIAGNOSTIC INPUT STUCK HIGH FAULT
TEST STEP
ACTION TO TAKE
P1 CHECK STATUS OF INDEPENDENT OBSERVER MODULE
(IOM) DIAGNOSTIC TROUBLE CODE (DTC)
NOTE: If an IOM to BCM Diagnostic Input Stuck High Fault occurs, the
Yes =
GO to P2.
12-volt auxiliary battery negative cable must be disconnected and
reconnected (power reset) to clear the latched fault from the BCM after the
concern is repaired. If the power reset is not performed, the BCM will not
allow charging.
NOTE:
If other BCM DTCs occurred along with DTC C1838 Charging System
Fault (IOM to BCM Diagnostic Input Stuck High Fault), carry out the
diagnostic procedures for those DTCs before carrying out this pinpoint test.
Refer to the BCM DTC Index in Section 100-07.
•
Disconnect and reconnect the 12-volt auxiliary battery negative cable.
•
Clear the BCM continuous DTCs.
No =
GO to P13.
•
With key OFF, monitor BCM PID IOMH F.
•
Connect the vehicle to a power control station (PCS) and press the
START button (if necessary) to begin charging.
•
Wait 30 seconds and retrieve continuous BCM DTCs.
•
Does the IOMH F PID indicate YES?
P2 CHECK POWER TO IOM AT TRACTION BATTERY SUPPORT
TRAY
•
With key OFF, disconnect traction battery support tray in-line C1939 and Yes =
GO to P3.
connect 104-Pin Breakout Box (BOB) to in-line C1939M using Traction
Battery Low-Voltage Service Cord; do not connect Traction Battery
Low-Voltage Service Cord to in-line C1939F.
•
With key OFF, measure the voltage between BOB pin 45 and ground
No =
REPAIR the PK/BK wire
(BOB pin 65).
between the electric vehicle

Is the voltage greater than 10 volts?
power distribution box
(EVPDB) and in-line
C1939M.
P3 CHECK POWER TO IOM
•
Disconnect the BOB from in-line C1939M, remove the traction battery,
Yes =
and connect Traction Battery High-Voltage Lockout and Diagnostic Tool
to the traction battery high-voltage two-pin C3994M.
