Checking the Shift Lock

Checking the shift lock

Checking fuses




- Ignition off.
Check that fuse 11C/24 (10A) is intact.
Replace the fuse if it is damaged.

Other information
- For further information about the fuses and relays, see the Wiring Diagram.

Is the fuse intact?

Yes - Checking the ground lead

No - Checking the cable

-------------------------------------------------

Checking the ground lead




- Ignition off
- Remove connector from Shift Lock module 3/156.
Check the cable between Shift Lock connector terminal #6 and ground terminal 31/6. Check for an open-circuit.
Remedy as necessary.

Is the cable OK?

Yes - Checking the power supply

No - Fault Found

-------------------------------------------------

Checking the power supply




- Ignition off
- Remove relay 2/29 from the central electronic module (CEM) relay holder
- Ignition on.
Check the voltage between relay holder 2/29 terminal #3 and ground.
