F 350 2WD Super Duty V10-6.8L (2009)
GO to F6.
-------------------------------------------------
F6 CHECK THE TBC MODULE PWM OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE
-
Ignition OFF.
-
Disconnect: TBC module C2142.
-
Ignition ON.
-
Measure the voltage between C4099-3, circuit CAT19, (BU), harness side and ground while operating the following lamps in turn:
-
Parking lamps
-
Stop lamps
-
Reversing lamps
-
Is any voltage present?
Yes
REPAIR circuit CAT19 (BU). CLEAR the DTCs. REPEAT the self-test.
No
The system is operating correctly at this time. INSPECT the 7-pin trailer tow connector for evidence of water intrusion or corrosion. INSPECT the trailer
tow C4099 harness for evidence of chaffed wiring or improper wire repair. REPAIR wiring as necessary. CLEAR the DTCs. REPEAT the self-test.
-------------------------------------------------
F7 CHECK THE TBC MODULE FOR MAXIMUM OUTPUT
NOTE: Battery voltage must be greater than 10 volts.
-
Ignition OFF.
-
Connect: TBC Module C2142.
-
Ignition ON.
-
NOTE: If the manual slider switch is held to the full left position for more than 5 minutes, the TBC module will automatically shut down.
-
Have an assistant press the manual slider switch fully to the left with a gain of 10 on the TBC module.
-
Measure voltage between C4099-3, circuit CAT19 (BU), harness side and ground.
-
Is the voltage greater than 10-12 volts?
Yes
The system is operating correctly at this time. INSPECT the 7-pin trailer tow connector for evidence of water intrusion or corrosion. INSPECT the trailer
tow C4099 harness for evidence of chaffed wiring or improper wire repair. REPAIR wiring as necessary. CLEAR the DTCs. REPEAT the self-test.
No
GO to F8.
-------------------------------------------------
F8 CHECK THE TBC MODULE PWM OUTPUT CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: TBC Module C2142.
-
Measure resistance between C4099-3, circuit CAT19 (BU), harness side and TBC module C2142-14, circuit CAT19 (BU), harness side.
