Signal too high
Status check
Measure the voltage on the combined instrument panel connector terminal #B4.

Does the voltmeter display a reading different from 0 volts?
Yes - Checking the wiring
No - Intermittent fault
-------------------------------------------------
Checking the wiring
Check the cable between combined instrument panel connector terminal #B4 and radio connector terminal #B7. Check for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
