DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST A: DTC B2513 BLOWER (FAN) CIRCUIT FAILURE
TEST STEP ACTION TO TAKE
•
Does the FANFDBK PID indicate ENABLE?
No = If fan operates, GO to A23.
If fan does not operate, GO
to A18.
A17 CHECK CIRCUIT 3605 (DB/W) FOR SHORT TO POWER
•
Remove the traction battery and connect Traction Battery High-Voltage Yes = REPAIR the DB/W wire.

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.
•
Connect Traction Battery High-Voltage Service Cord to traction battery
support tray in-line C1935F and in-line C1935M.
•
With key OFF, disconnect recirculation fan C1801.
•
With key ON, measure the voltage between BOB pin A28 and ground
(BOB pin A33).
•
Is the voltage greater than 10 volts?
A18 CHECK POWER TO RECIRCULATION FAN
•
Remove the traction battery and connect Traction Battery High-Voltage Yes = REPLACE the recirculation

•
Measure the voltage between pin 2 (Y/LG wire) and pin 1 (BK wire) on
recirculation fan C1801.
•
Is the voltage greater than 10 volts?
A19 CHECK GROUND TO RECIRCULATION FAN
•
With key OFF, measure the resistance between pin 1 (BK wire) on Yes = GO to A20.
recirculation fan C1801 and ground (BCM case).
•
Is the resistance less than 5 ohms?
No = REPAIR the BK wire.
A20 CHECK POWER TO RECIRCULATION FAN RELAY
•
Disconnect recirculation fan relay C2038 and measure the voltage Yes = GO to A21.
between pin 86 (Y/BK wire), pin 87 (Y/BK wire) on recirculation fan
relay C2038 and ground.
•
Are the voltages greater than 10 volts?
No = REPAIR the Y/BK wire(s).
A21 CHECK RECIRCULATION FAN RELAY
•
Connect 12-volts to pin 86 and ground to pin 85 on the recirculation fan Yes = GO to A22.
