Pinpoint Test B: DTC B1483 - BRAKE PEDAL INPUT CIRCUIT FAILURE
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.
- B1 CHECK CIRCUIT 7-CF65 (YE/VT) FOR AN OPEN
- Key in OFF position.
- Disconnect: ABS Module C155.
- Measure the voltage between ABS module C155-26, circuit 7-CF65 (YE/VT), harness side and ground.
- Is the voltage greater than 10 volts?
- Yes : GO to B2.
- No : REPAIR the circuit in question 7-CF65 (YE/VT). CLEAR the DTC. REPEAT the self-test.
- B2 CHECK CIRCUIT 8-CF65 (WH/VT)
- Measure the voltage between ABS module C155-40, circuit 8-CF65 (WH/VT), harness side and ground, while applying and releasing the brake pedal.
- Is the voltage greater than 10 volts with the brake pedal applied, and 0 volts with the brake pedal released?
- Yes : INSTALL a new pedal travel switch (PTS). REFER to EXTERIOR LIGHTING . CLEAR the DTC. REPEAT the self-test.
- No : GO to B3.
- B3 CHECK CIRCUIT 8-CF65 (WH/VT) FOR A SHORT TO GROUND
- Measure the resistance between ABS module C155-40, circuit 8-CF65 (WH/VT), harness side and ground.
- Is the resistance greater than 10,000 ohms?
- Yes : GO to B4.
- No : REPAIR the circuit in question 8-CF65 (WH/VT). CLEAR the DTC. REPEAT the self-test.
- B4 CHECK CIRCUIT 9-CF65 (BN/WH) FOR A SHORT TO VOLTAGE
- Measure the voltage between ABS module C155-24, circuit 9-CF65 (BN/WH), harness side and ground.
- Is voltage present?
- Yes : REPAIR the circuit. CLEAR the DTC. REPEAT the self-test.
- No : INSTALL a new pedal travel switch (PTS) switch. REFER to EXTERIOR LIGHTING . CLEAR the DTC. REPEAT the self-test.
