DIAGNOSIS AND TESTING (Continued)
ROUTINE 9: VEHICLE DOES NOT CHARGE (NIMH VEHICLES)
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 Traction Battery Low Voltage Service Cord to traction battery
support tray in-line C1939F and in-line C1939M.
• With key OFF, disconnect the battery temperature sensor in question and
one of the other temperature sensors.
• Connect jumper wires between the connector for the temperature sensor
in question and the known good temperature sensor that was
disconnected.
• With key ON, monitor BCM PIDs TMPSEN1, TMPSEN2, and
TMPSEN3.
• Does the TMPSEN PID that indicated less than -25°C (-13°F) still
indicate the same value?
9-10 CHECK BATTERY TEMPERATURE SENSOR (HIGH
TEMPERATURE DELTA CONDITION)
• Remove the traction battery and connect Traction Battery High-Voltage
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin
C3994M.
• Connect Traction Battery High Voltage Service Cord to traction battery
support tray in-line C1935F and in-line C1935M.
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 Low Voltage Service Cord to traction battery
support tray in-line C1939F and in-line C1939M.
• With key OFF, disconnect the battery temperature sensor in question and
one of the other temperature sensors.
• Connect jumper wires between the connector for the temperature sensor
in question and the known good temperature sensor that was
disconnected.
• With key ON, monitor battery control module (BCM) PIDs TMPSEN1,
TMPSEN2, and TMPSEN3.
• Does the TMPSEN PID that indicated a greater than 20°C (36°F)
difference from the other TMPSEN PIDs still indicate a greater than
20°C (36°F) difference?
9-11 CHARGE TRACTION BATTERY TO FULL STATE OF
CHARGE (SOC)
• Disconnect and reconnect the 12-volt auxiliary battery negative cable.
NOTE: If the EMG PO indicates ENABLE after pressing the START
button on the power control station (PCS), GO to 9-13.
• Charge the traction battery to full SOC.
• With key OFF and vehicle on-charge, monitor BCM PIDs EMG PO
and BCM OP.
• Does the BCM OP PID still indicate 96 (no charge-EPO detected)?

Powertrain Diagnostic Routines Identification
TEST STEP ACTION TO TAKE
No = REPLACE the battery
temperature sensor in
question.
Yes = REPLACE the BCM.
REFER to Section
414-03B.
No = REPLACE the battery
temperature sensor in
question.
Yes = REPEAT this test step. The
traction battery has not
reached full SOC.
No = System OK.
