Power steering circuit 1
Check the position sensor for the power steering circuit 1 with its cable harness and connectors. The coordinator's pin for power steering circuit 1 should be grounded when the engine is off. Check that the position sensor for power steering circuit 1 is working. If not, clean the position sensor. For checking and cleaning, see Workshop manual, 13-05 Power steering gear, Dual-circuit steering using power steering gears TAS86 and TAS87. Note: The engine must be switched off so that the fault code will not be active.

Diagnostic depth
The signal from the power steering circuit 1 has been implausible in relation to the engine speed.
The signal has been inactive (24 V) at the same time as the engine speed has been lower than 100 rpm. The active signal in this case is grounding, which means that an inactive signal corresponds to 24 V. The fault may be due to the circuit being either shorted to voltage or broken.
