Speedometer and odometer (MIU 1)


Fault symptoms

Speedometer needle does not move Odometer and trip meter stationary.

Diagnostic procedure



1. Jack up LH rear wheel.

2. Unplug the main instrument display panel's three connectors and connect the Scan Tool's test leads to pin 7 (black 12-pin connector) and ground. First select "TEST" and then "PULSE". Spin the rear wheel by hand and check whether pulses are generated. About 30 Hz when the wheel is rotated 1 revolution per second. If pulses are generated, proceed to point 5.

3. If no pulses are generated, check the wiring by connecting a BOB to the ABS control module's connector. The main instrument display panel and ABS control module should not be connected.


4. Check the wiring for continuity/shorting between pin 7 (black 12-pin connector) of the main instrument display panel connector and pin 22 of the ABS control module.

If the lead is OK, continue fault diagnosis as described in "Brakes, ABS" .

5. Check the conductive foil on the rear of the main instrument display panel for an open circuit between pin 7 (black 12-pin connector) and the screw marked "SEN". If the conductive foil is intact and the speedometer and odometer do not work, the fault is probably in these instruments. The complete main instrument display panel will have to be changed. If there is an open circuit in the conductive foil, change the foil.
