P26F1Starter Relay A Stuck Off
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P26F1 is the opposite case to P26F0: the module commands starter relay A on, but the expected reaction never arrives, so the starter receives no power. Possible reasons are burnt or contaminated contacts, a coil that no longer pulls in, or a missing feed on the load side, for example a blown fuse or a loose battery cable at the relay. No maker documents P26F1 publicly. As reference points remain FCA, whose Jeep bulletins treat its two starter relays as separately monitored outputs and describe intermittent no-crank conditions, and GM, whose 2018 tables monitor the starter relay A driver. Because a dead relay looks like a dead starter, check whether the starter terminal receives voltage during cranking before replacing the motor.
