P0615Starter Relay A Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- The engine module switches the starter relay coil through its own driver – GM petrol engines with 12 V stop-start use a low-side driver, the Saab 9-4X switches 12 V to the coil. CARB requires output components to be checked for open and short circuits. GM sets the codes after two trips on stop-start engines, while GM diesels (2016) and the Saab 9-4X store them without the check engine light. At Ford an active starter code blocks stop-start. P0615 is the open or general circuit fault: GM measures the driver output with the driver off and sets the code at 200 kΩ or more after 40 of 50 samples at 50 ms. Chrysler traced no-start cases with P0615 to a harness chafed or pinched at the engine mount near the starter. Short to ground and to voltage are P0616 and P0617; the start request input is P0512.
