Modern Renaults use on the brake pedal:
| Cause | Check | Repair | |-------|-------|--------| | | Cranking voltage <9.6V | Replace battery / charge | | Loose steering column connector | 6-pin connector at EPS module (under dash, on column) | Reseat, clean with contact cleaner | | CAN bus termination | Measure resistance between CAN H & L (disconnected battery): should be 60Ω (ends: 120Ω each) | Locate open termination resistor (in EPS or ABS unit) | | Corroded ground | Ground G03 or G07 (near left strut tower or under dash) | Remove, sand, reattach with dielectric grease | | Water ingress | Check UCH (under glovebox) or EPS module for corrosion | Dry, repair tracks, replace module if needed |
| Cause Category | Specific Issue | |----------------|----------------| | | Short to ground / short to battery / open circuit in solenoid wiring inside TCU | | Mechanical | Solenoid valve stuck due to metal debris or degraded transmission fluid | | Hydraulic | Low hydraulic pressure due to worn pump or fluid leak (affects solenoid operation) | | TCU Hardware | Failed driver chip (MOSFET) inside the TCU – common in early 6DCT250 units | | Battery/Charging | Low voltage (<11V) or unstable voltage causes solenoid driver misbehavior | | Water ingress | Corrosion in TCU connector (especially after pressure washing engine bay) | renault dtc f00316 work
: Check the oxygen sensor for any signs of damage or wear. Consider replacing it if necessary.
…it sets and may trigger limp mode.
Before replacing any parts, perform this structured diagnostic work.
The engine may fail to engage or turn over slowly, even if the ignition lights come on. Modern Renaults use on the brake pedal: |
In some early Renault Megane IV and Kadjar models, a software bug caused false F00316 codes. A simple ECU reflash solves it.
