U1418 - Implausible Right Wheel Distance Signal Received:
1. Set Condition: The PCM gets an implausible signal over the Can C circuit from the ABS module or the FCM (non-ABS). The circuit is continuously monitored.
2. Possible causes:
a. Vehicle speed sensor fault active in ABS module.
b. Can C bus shorted.
c. Can C bus open.
d. Faulty ABS module
e. Faulty PCM
3. Diagnosis & Repair:
a. Test vehicle speed sensor. Failure = replace.
b. Test ABS module. Failure = replace
c. Test/visually check ABS module harness connection and wiring for damage or loose connections.
d. Test/visually check ABS sensor harness connection and wiring for damage, dirt, or loose connection.
e. Check/Clean main PCM harness connection.
f. Test PCM (StarScan)
There's not much here besides checking the wiring and connections you or your bud can do. If you've replaced the right rear wheel ABS sensor, that's a good first step.
Cost at the dealer will be one hour diagnostics time (shop rate) + parts and labor to replace the faulty component. Cost will depend on what needs to be replaced. Hopefully it's an ABS module vs. the PCM!
Does he have the headlights coming on when the remote unlocking activates?
check the 10A fuse for the steering control module/steering column control module. If it has blown, check to see if you have courtesy headlights on unlocking the car is activated in the EVIC. If you have, disable that feature & replace the fuse, (because thats what seems to blow it)
I had a similar error - anything related to the indicator stalk (high beams, wipers/washers etc, indicators etc), plus cruise control, plus front windows airbags, traction control etc etc stopped working all because of that. The individual fuses for those features remained OK & unblown
more than likely its one of the front TPMS sensors in that case - we've had a rash of weird faults over here caused by them - everything from airbags to imobiliser faults. They cause a short in the canbus
