P0692 — Cooling Fan 1 Control Circuit High

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Holden

About P0692

P0692 is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Holden vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0692 is stored, the module has detected a signal or supply voltage higher than the expected operating range.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0692 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The powertrain control module (PCM) controls Cooling Fan 1 through a fan relay to manage engine and air conditioning system temperatures, and it monitors the fan relay control circuit voltage to verify correct operation. When the fan is commanded off the control circuit should not show battery voltage. DTC P0692 is set when the PCM detects a voltage exceeding normal battery potential on the control circuit, indicating a short to constant power or internally welded relay contacts, for longer than the specified time, often around 5 seconds. A fan stuck on or a shorted control circuit is the typi...
