414-03B-59 414-03B-59 High Voltage/Traction Battery — Nickel Metal Hydride
DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST Q: IOM TO BCM DIAGNOSTIC INPUT STUCK LOW FAULT
TEST STEP ACTION TO TAKE
•
Is the resistance greater than 10,000 ohms?
No = REPAIR the R/BK wire.
Q3 CHECK BCM TO IOM DIAGNOSTIC OUTPUT CIRCUIT 4007
(Y/LG) FOR SHORT TO POWER
•
Connect Traction Battery Low-Voltage Service Cord to traction battery Yes = REPAIR the Y/LG wire.
support tray in-line C1939F and in-line C1939M.
•
Connect Traction Battery High-Voltage Service Cord to traction battery No = REPLACE the IOM.
support tray in-line C1935F and in-line C1935M.
•
With key ON, measure the voltage between BOB pin B11 and ground
(BOB pin A33).
•
Is the voltage greater than 0 volt?
PINPOINT TEST R: DTC C1859 PRNDL INPUT #2 CIRCUIT FAILURE
TEST STEP ACTION TO TAKE
R1 CHECK STATUS OF DIGITAL TRANSMISSION RANGE (DTR)
SENSOR SIGNAL TR2 TO BATTERY CONTROL MODULE (BCM)
NOTE: Verify the transmission range selector lever is in the Park (P)
Yes = System OK. CHECK wiring
position.
for intermittent connections.
•
With key ON, monitor BCM PID TRANSGR.
•
Does the TRANSGR PID indicate D6 PRK?
No = GO to R2.
R2 CHECK CIRCUIT 3501 (DB) (OUTSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
•
With key OFF, disconnect traction battery support tray in-line C1939 and Yes = GO to R3.
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, disconnect digital transmission range (DTR) sensor No = REPAIR the DB wire.
C4996 and measure the resistance of the DB wire between pin 5 on DTR
sensor C4996 and BOB pin 40.
•
Is the resistance less than 5 ohms?
R3 CHECK CIRCUIT 3501 (DB) (INSIDE OF TRACTION BATTERY
SUPPORT TRAY) FOR OPEN
•
Disconnect the BOB from in-line C1939M, remove the traction battery, Yes = GO to R4.
and connect Traction Battery High-Voltage Lockout and Diagnostic Tool
to the traction battery high-voltage two-pin C3994M.
No = REPAIR the DB 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 and in-line C1939M using Traction Battery Low-Voltage
Service Cord.
•
With key OFF, disconnect BCM C1987 and measure the resistance of the
DB wire between pin 17 on BCM C1987 and BOB pin 40.
•
Is the resistance less than 5 ohms?
R4 CHECK FOR INTERMITTENT CONCERN(S)
•
With key OFF, reconnect DTR sensor C4996 and BCM C1987. Yes = REPLACE the BCM.
•
Carry out the on-demand self-test for the BCM. No = System OK. CHECK wiring
•
Does DTC C1859 PRNDL Input #2 Circuit Failure occur?
for intermittent connections.
