Component Tests and General Diagnostics


Start fault diagnosis by checking:
1 Fuses.
2 Power supply (+54 circuit).
3 Grounding.
4 The pins of the control module connector for possible slide-out.

Fault diagnosis is carried out in the self-diagnostics mode. To enter the diagnostics mode, consult the table below.

To leave the diagnostics mode, increase speed to above 32 km/h (20 mph) or switch off the ignition.

If you make a mistake while in diagnostics mode you will be returned automatically to point 5 and will have to start again from there.
