P0693 Saturn Code - Cooling Fan 2 Control Circuit Low

Quick Answer

The Engine Control Module (ECM) grounds the low-speed relay, which is the Fan Low relay, and the high-speed relay, which is the Fan High relay, control circuits through an internal solid-state device called a driver. Common causes include Faulty Cooling Fan 2 Relay, Cooling Fan 2 Relay harness is open or shorted, Cooling Fan 2 Relay circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What it means: P0693 Saturn indicates Cooling Fan 2 Control Circuit Low.
Common causes: Common causes include Faulty Cooling Fan 2 Relay, Cooling Fan 2 Relay harness is open or shorted, Cooling Fan 2 Relay circuit poor electrical connection.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0693 Saturn Description

The Engine Control Module (ECM) grounds the low-speed relay, which is the Fan Low relay, and the high-speed relay, which is the Fan High relay, control circuits through an internal solid-state device called a driver. The primary function of the driver is to supply the ground for the component being controlled. Each driver has a fault line that is monitored by the ECM. When the ECM is commanding a component ON, the voltage potential of the control circuit should be low, near 0 volts. When the ECM is commanding the control circuit to a component OFF, the voltage potential of the circuit should be high, near battery voltage. If the ECM detects that the actual state of the control circuit does not match the expected state, a Diagnostic Trouble Code (DTC) will set.
