CONTROL, set the active command PUMP/VBC to ON, and measure
relay.
the resistance between pin 86 on the blower motor relay connector and
ground.
•
Is the resistance less than 5 ohms?
No =
GO to K12.
K12 CHECK CIRCUIT 3020 (LB) FOR OPEN
•
Connect 104-Pin Breakout Box (BOB) to IAA module C1945; leave IAA Yes =
REPLACE the IAA module.
module disconnected.
REFER to

With key OFF, measure the resistance of the LB wire between pin 86 on
No =
REPAIR the LB wire.
the blower motor relay connector and BOB pin 19.
•
Is the resistance less than 5 ohms?
PINPOINT TEST L: DTC B2514 BLOWER (FAN) CIRCUIT SHORT TO VBAT
TEST STEP
ACTION TO TAKE
L1 CHECK FOR BLOWER/FAN SYSTEM DIAGNOSTIC TROUBLE
CODES (DTCs)
•
Carry out the on-demand self-test for the interface adapter assembly Yes = GO to
(IAA) module and check for blower/fan system DTCs.
•
Do DTC B2515 Heater Blower Relay Circuit Failure and DTC B2516 No =
GO to L2.
Blower Control Circuit Failure also occur?
L2 CHECK BLOWER/FAN SENSE VOLTAGE
•
Enter IAA module active command mode CLIMATE SYSTEM
Yes =
GO to L3.
CONTROL, monitor the IAA module PID BFSV, and set the active
command PUMP/VBC to OFF.
•
Is the BFSV PID greater than 10 volts?
No =
System OK. CHECK wiring
for intermittent connections.
L3 CHECK BLOWER MOTOR RELAY
•
With key OFF, remove the blower motor relay from the electric vehicle
Yes =
REPLACE the blower motor
power distribution box (EVPDB) and measure the resistance between
relay.
terminals 30 and 87 on the blower motor relay.
•
Is the resistance less than 5 ohms?
No =
GO to L4.
L4 CHECK CIRCUIT 181 (BR/O) FOR SHORT TO POWER
•
With key OFF, disconnect blower motor C161.
Yes =
REPAIR the BR/O wire.
