  P0694 00


Cooling Fan 2 Control Circuit, Short to B+

Fault symptom

Radiator fan malfunction.

No A/C function.

Torque Reduction

On-board diagnosis

Type of diagnosis:

Continuous

Enable criteria:

Battery voltage must be between 11 - 16 V.
Engine running.
Output is active.

Fault criteria:

When voltage on the output exceeds 2.0 V for more than 1 s.

Dependent:

None

System reaction to a fault:

Switches off output to A/C relay.
Engine torque limitation (which is a function of vehicle speed, intake air temperature and number of incorrect fan stages).

OK report:

Fault criteria NOT fulfilled for 5 s.

Fault handling:

Type III without Check Engine.
(See section Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness

Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
