High Voltage/Traction Battery — Nickel Metal Hydride
DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST A: DTC C1862 CONTACTOR CIRCUIT FAILURE
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 carrying out the following steps. Failure to
follow this warning may result in severe personal injury or death.
•
Connect Traction Battery High-Voltage Service Cord to traction battery
support tray in-line C1935F and in-line C1935M.
•
Connect 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 contactor box C1982.
•
With key ON, measure the voltage between BOB pin 17 and ground
(BOB pin 65).
•
Is the voltage greater than 0 volts?
A13 CHECK AUXILIARY CONTACTOR RELAY FEEDBACK
STATUS
•
With key ON, monitor IAA module AUXCN I.
Yes =
REPLACE the IAA module.
•
Does the AUXCN I PID indicate ENABLED?
No =
System OK. CHECK wiring
for intermittent connections.
A14 CHECK AUXILIARY CONTACTOR RELAY STATUS SIGNAL
(OPEN FAULT)
•
Connect 104-Pin Breakout Box (BOB) to IAA module and IAA module
Yes =
System OK. CHECK wiring
C1945.
for intermittent connections.
•
Enter IAA module active command mode AUXILIARY SYSTEM
No =
GO to A15.
CONTROL, set the active command AUX CONT to CLOSE, and
measure the voltage between BOB pin 26 and ground (BOB pin 80).
•
Is the voltage greater than 10 volts?
A15 CHECK AUXILIARY CONTACTOR RELAY CONTROL SIGNAL
(OPEN FAULT)
•
Enter IAA module active command mode AUXILIARY SYSTEM
Yes =
GO to A18.
CONTROL, set the active command AUX CONT to CLOSE, and
measure the voltage between BOB pin 42 and ground (BOB pin 80).
•
Is the voltage greater than 10 volts?
No =
GO to A16.
A16 CHECK CIRCUIT 3998 (GY) FOR SHORT TO GROUND
•
Disconnect BOB from IAA module; leave BOB connected to IAA
Yes =
REPLACE the IAA module.
module C1945.
•
With key OFF, measure the resistance between BOB pin 42 and ground
No =
GO to A17.
(BOB pin 80).
•
Is the resistance greater than 10,000 ohms?
A17 CHECK CIRCUIT 3998 (GY) BETWEEN IAA MODULE AND
TRACTION BATTERY SUPPORT TRAY FOR SHORT TO GROUND
•
With key OFF, disconnect traction battery support tray in-line C1939.
Yes =
REMOVE the traction
battery and REPAIR the GY
wire between the contactor
box and in-line C1939F.
•
With key OFF, measure the resistance between BOB pin 42 and ground
No =
REPAIR the GY wire
(BOB pin 80).
between the IAA module
•
Is the resistance greater than 10,000 ohms?
and in-line C1939M.
A18 CHECK CIRCUITS 3998 (GY) AND 3999 (DB/LG) BETWEEN
IAA MODULE AND TRACTION BATTERY SUPPORT TRAY FOR
OPEN(S)
