F 350 2WD Super Duty V10-6.8L (2009)
-
Is the voltage between 4.5 and 5.5 volts?
Yes
CONNECT C147 and attempt to recreate the DTC by flexing the wire harness at the brake pressure transducer. If the DTC returns, REPAIR circuit
LCA16 (GN). CLEAR the DTCs. REPEAT the self-test. If the DTC does not return, CHECK the brake pressure transducer connector for corrosion,
pushed-out pins and spread terminals. REPAIR the brake pressure transducer connector as necessary. CLEAR the DTCs. REPEAT the self-test.
No
If the voltage is greater than 5.5 volts, GO to C3.
If the voltage is less than 4.5 volts, GO to C4.

Measure the voltage between brake pressure transducer C147-3, circuit LCA16 (GN), harness side and ground.
-
Is any voltage present?
Yes
REPAIR circuit LCA16 (GN). CLEAR the DTCs. REPEAT the self-test.
No
CONNECT C147 and C2142, ATTEMPT to recreate the DTC by flexing the wire harness at the brake pressure transducer. If the DTC returns,
REPAIR circuit LCA16 (GN). CLEAR the DTCs. REPEAT the self-test. If the DTC does not return, CHECK the brake pressure transducer connector
for corrosion, pushed-out pins and spread terminals. REPAIR the brake pressure transducer connector as necessary. CLEAR the DTCs. REPEAT the
self-test.
If the connectors are OK, GO to C7.
