100-09-7 100-09-7 Powertrain Diagnostic Routines Identification
DIAGNOSIS AND TESTING (Continued)
ROUTINE 1: VEHICLE DOES NOT START/VEHICLE QUITS WHILE DRIVING (LEAD ACID VEHICLES)
TEST STEP ACTION TO TAKE
1-20 CHECK KEY RUN/START SIGNAL TO CONTACTOR BOX AT
TRACTION BATTERY SUPPORT TRAY
•
With key OFF, disconnect in-line C1939 on the traction battery support Yes = GO to 1-21.
tray.
•
Connect BOB to in-line C1939M using Traction Battery Low Voltage No = REPAIR circuit 295
Service Cord; do not connect Traction Battery Low Voltage Service Cord (LB/BK).
to traction battery support tray in-line C1939F.
•
With key ON, measure the voltage between BOB pin 21 and ground
(BOB pin 65).
•
Is the voltage greater than 10 volts?
1-21 CHECK CIRCUIT 295 (LB/PK) (INSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
•
Disconnect the BOB from in-line C1939M, remove the traction battery, Yes = REPLACE the contactor
and connect Traction Battery High-Voltage Lockout and Diagnostic Tool box. REFER to Section
to the traction battery high-voltage two-pin C3994M. 414-03A .
No = REPAIR the LB/PK 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 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 and measure the
resistance of the LB/PK wire between pin 13 on contactor box C1982
and BOB pin 21.
•
Is the resistance less than 5 ohms?
ROUTINE 2: VEHICLE DOES NOT START/VEHICLE QUITS WHILE DRIVING (NIMH VEHICLES)
TEST STEP ACTION TO TAKE
2-1 CHECK AUXILIARY BATTERY VOLTAGE
•
With key OFF, measure the voltage of the 12-volt auxiliary battery. Yes = GO to 2-2.
•
Is the voltage greater than 11.5 volts?
No = CARRY OUT the Auxiliary
Battery Capacity Test.
REFER to Section 414-02 .
2-2 CHECK STATUS OF BATTERY CONTROL MODULE (BCM)
OPERATING STATE
•
With key ON, monitor BCM PID BCM OP. Yes = If BCM OP PID indicates
48, GO to 2-3.
If BCM OP PID indicates
49, CHARGE the traction
battery. REFER to Section
100-05 .
If BCM OP PID indicates
51, GO to 2-6.
If BCM OP PID indicates
54, GO to 2-9.
•
Does the BCM OP PID indicate 48 (shutdown-low battery module
No = GO to 2-10.
voltage), 49 (shutdown-low SOC), 51 (no start-battery under
temperature), or 54 (shutdown-battery over temperature)?
2-3 CHARGE TRACTION BATTERY TO FULL STATE OF CHARGE
(SOC)
