Starter Relay C Control Circuit Low

Where it lives

For P2AF3, the circuit described runs through the relay. The description of P2AF3 reports a fault at the relay.

Check these first

• A short to ground on the starter relay C control wire
• A failed starter relay C coil
• A chafed starter relay C harness grounded on the engine
• A control module driver fault on the starter relay C output

What to do next

1. Scan all modules and read the starter relay C command state
2. Inspect the starter relay C harness for chafing or a pinched section
3. Test the starter relay C control wire for a short to ground
4. Measure starter relay C coil resistance against a known good relay
5. Replace starter relay C if the control circuit tests clean
6. Clear the code and retest
