SCC Trip Computer

FAULT DIAGNOSIS HINTS
The trip computer is activated by turning the ignition switch to the Drive position.
1. Check that fuses 13 and 19 are intact and supplied with current.
2. Check that current is supplied to pin 1 of the trip computer, via clock 49 and pin 6.
3. Check that current is supplied to terminal 1 of vehicle speed sensor 132 and then from terminal 2 of the vehicle speed sensor to terminal 9 of the EDU trip computer.
4. Check that current is supplied from the EDU to the SCC.
5. Check that the contact surfaces of the connectors are undamaged and clean. This is important as the currents involved are weak.
6. Check the wiring harness and ground connections.
