CARRYING OUT THE BATTERY MODULE DIAGNOSTIC TEST
NOTE: If DTC B1671 Battery Module Voltage Out of Range occurs along
with DTC B2236, do NOT carry out this test step. Go to Pinpoint Test B.
• With key ON, perform Battery Module Diagnostic Test. Refer to the
procedure in Traction Battery System.
• Does the Battery Module Diagnostic Test indicate to replace any

NOTE: Verify the power control station (PCS) charger cord is not plugged
into the charger inlet before carrying out this test step.
NOTE:
Disregard traction inverter module (TIM) DTC C1862 Contactor Circuit
Failure when carrying out the Diagnostic Process for this test step. DTC
C1862 occurs due to the connection of the Traction Battery High-Voltage
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin
connector C3994M.
• Carry out the Diagnostic Process. Refer to Section 100-07.
• Do any DTCs occur?
E2 CHECK INSTRUMENT CLUSTER INDICATORS
• With key ON, check to see if the following instrument cluster indicators

• Wait approximately 30 seconds and reconnect the auxiliary battery
negative cable.
• Connect the vehicle to the PCS and press the START button to begin
