DTC B2462 RHD Navigation
Diagnostic Instructions
DTC Descriptor
DTC B2462 00: Global Positioning System Sensor Receiver Failure
DTC B2462 08: Global Positioning System Sensor Signal Invalid
Circuit Description
The navigation antenna is connected to the navigation module with a coax cable. The navigation module polls the data from the navigation antenna once every second.
Conditions for Running the DTC
| • | The system voltage is at least 9.5 volts and no more than 15.5 volts. |
Conditions for Setting the DTC
| • | GPS antenna output above threshold. |
| • | General GPS receiver error during test. |
Conditions for Clearing the DTC
| • | The navigation module detects a proper signal from the GPS antenna. |
| • | A history DTC clears after 50 fault-free ignition cycles. |

Circuit/System Testing
- Ignition OFF, disconnect the GPS coaxial cable from the navigation module.
- Ignition ON, test for 4-5.5 volts between the center conductor and the shield of the coaxial cable.
| ⇒ | If not within the specified range, replace the navigation module. |
- If all circuits test normal, replace the GPS antenna.

Circuit Description
The Global Positioning System (GPS) antenna is connected to the telematics module
with a coax cable. The telematics module polls the data from the GPS antenna once
every second.
Conditions for Running the DTC
| • | System voltage is between 9-16 volts. |
| • | Ignition switch is in the ON position. |
Conditions for Setting the DTC
| • | GPS antenna output above threshold. |
| • | General GPS receiver error during test. |
Conditions for Clearing the DTC
A history DTC clears after 50 fault-free ignition cycles.
Diagnostic Aids
An intermittent condition may be caused by the following:
| • | Rubbed through wire insulation |
| • | Broken wire inside the insulation |

Circuit/System Testing
- Ignition ON, disconnect the GPS coaxial cable from the GPS antenna. Verify
there is 4 to 5.5 volts between the centre conductor and the shield of the coaxial
cable.
| ⇒ | If 4 to 5.5 volts are present, replace the GPS antenna. |
- Ignition OFF, disconnect the GPS coaxial cable from the telematics module.
Test the resistance of the GPS coaxial cable centre conductor from end to end. Verify
the resistance is less than 5 ohms.
| ⇒ | If the resistance greater than 5 ohms, replace the GPS coaxial cable |
- Test the resistance of the GPS coaxial cable between the centre conductor
and the outer conductor. Verify there is infinite resistance between both conductors.
| ⇒ | If there is less than infinite resistance between the inner conductor and the
outer conductor of the GPS coaxial cable, replace the GPS coaxial cable. If the GPS
coaxial cable tests normal, replace the telematics module. |
