Circuit/System Description
The radio receives a vehicle speed signal from the electronic
brake control module in order to correlate actual vehicle speed to
the movement of the vehicle calculated by the navigation system and
reported serial data.
Conditions for Running the DTC
| • |
Battery voltage must be
between 9-16 V. |
Conditions for Setting the DTC
| • |
Vehicle speed from serial data
is more than 5 km/h (3 mph) and vehicle speed pulse from the
electronic brake control module is 0 km/h (0 mph). |
| • |
Vehicle speed calculated from
the navigation processing software is more than 36 km/h (22 mph)
and vehicle speed pulse from the electronic brake control module is
0 km/h (0 mph) for 10 seconds continuously. |
Action Taken When the DTC Sets
| • |
Turn by turn route navigation
may be inoperative. |
| • |
Vehicle indicated location may
be inaccurate. |
Conditions for Clearing the DTC
| • |
The condition responsible for
setting the DTC no longer exists. |
| • |
A history DTC clears after 100
malfunction-free ignition cycles. |

Circuit/System Testing
Note: Diagnose any antilock
brake system (ABS) related DTCs before performing this
diagnostic.
| 1. |
Ignition OFF, disconnect the
X4 harness connector at the A11 radio. |
| 2. |
Ignition ON, operate the
vehicle drive wheels at 5 mph. Test for 3-7 Hertz between the
signal circuit terminal 20 and ground. |
| ⇒ |
If not within the specified range, test the signal
circuit terminal 20 for an open, high resistance, short to ground
or short to voltage. If the circuit tests normal replace the K17
electronic brake control module. |
| 3. |
If the circuit tests normal,
replace the A11 radio. |
Repair Instructions
