C0735Electric Power Steering Module Internal Fault
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- No known public source uses C0735; it is absent from the published J2012 lists, from NHTSA bulletins and from maker indexes. Carmakers report an internal EPS controller fault under other codes. GM uses C056D as a general hardware fault and asks technicians to reprogram the module first when symptom 39 is set (PIT5213B, 2014-15 trucks and SUVs). Stellantis uses C2217-00; on the 2023 Wagoneer and Grand Wagoneer it came with loss of assist and a steering lamp and was improved by new software (08-147-23), while on the 2019 Cherokee bulletin 08-034-20 excludes cases where C2217 is active and assist is gone with the engine running. Nexteer stresses redundant hardware and parallel software paths so that a single internal fault does not remove all assist at once.
