• Ignition off
• Disconnect the required connections from the relevant unit.

Check that the male and female terminals on the unit connectors are undamaged and secure (cannot be pressed in). Check that the cables to the female terminals are secured to the terminal pins.

• To access and replace the Road Traffic Information (RTI) control module, see Road Traffic Information Module (RTI), Replacing .

Different adapters are required depending on what terminal should be checked on the breakout box.

Terminals C and J must be connected to adapter 9512882 .

Terminals D, B, K and N must be connected to adapter 9511508 .

Terminal M must be connected to adapter 9511463 .

Terminals E, F, O and P must be connected to adapter 9511509 .

The breakout box is designed to facilitate reading off the control module input and output signals when the control module is connected; and the cable and component resistance when the control module is disconnected. The use of a breakout box reduces the risk of accidental short-circuited cables and damage to the connector pins.
