Signal Too High. Intermittent Fault

Signal too high. Intermittent fault

Checking the wiring
Check the relay coil driver circuit for an intermittent short-circuit to supply voltage: Measure the voltage between terminal #2 in the relay base and relay 2/112.
For further information about a short-circuit to supply voltage, see Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

Hint: The voltage between terminal #2 and ground should be approximately 0 V.








If the voltmeter displays an incorrect value replace the control module.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
