Vehicle Speed Fault
- The vehicle speed signal through
CAN communication is faulty.
- Check the CAN communication line
for open and short.
- Check the ABS/ESP and TCU
communication lines.
- Check the ECU wiring harness.
- Replace the ECU if required.
P1501
Faulty Variant Coding
(Vehicle Speed)
- If the vehicle sensor coding is set to
YES (for vehicle with ABS), the
vehicle speed input is faulty when
the vehicle speed is below 15 km/h
with the engine running at 1,600
rpm.
- If the vehicle sensor coding is set to
NO (for vehicle with CAN and ABS/
ESP), the corresponding DTC is not
shown.
- Check the vehicle speed sensor
coding.
P1503
Faulty Vehicle Speed
Sensor Input
- If the vehicle sensor coding is set to
YES (for vehicle with ABS), the
amount of pulses of the speed
pulse ring for vehicle speed
detection is more than the specified
value.
- Specified pulse: 52 pulses/rev.
- Check the vehicle speed sensor
coding.
