Signal Missing

Signal missing

Checking wiring and terminals
Check the connector between the road traffic information (RTI) control module and the GPS antenna. Check for contact resistance and oxidation.
Check the wiring between the GPS antenna and road traffic information (RTI) control module terminals #G1 and #G2. Check for a short-circuit to ground. Check for an open-circuit.

Hint: If the GPS antenna is using more than 100 mA, the current is "shut off" in the control module and drops to 0 mA.

Remedy as necessary.

Was a fault detected?

Yes - Verification

No - Replacing the component

-------------------------------------------------

Replacing the component
Fault-tracing indicates an internal fault in the GPS antenna. Replace according to Antenna, GPS, replacing Service and Repair.

Select "Continue" when corrective action has been carried out.

Continue - Verification

Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.

Hint: Leave the car outside in an open place until the road traffic information (RTI) control module has found at least 3 satellites.
This can take up to 15 minutes.

Is the system in contact with enough satellites?

Yes - Fault Found

No - Fault-tracing information

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.

Do you want to exit fault-tracing?
