Thanks mate. I've checked and it's definitely plugged in, so I guess next step is to get the multimeter out and check at the connection to the solenoid when the clutch pedal is depressed? Do you happen to know what the most likely faulty component is?

I haven't had a chance to get the multimeter onto it yet, but just in case someone else ever has this problem. It seems that changing into 5th before moving over to reverse, leaving the clutch in, lets it go into reverse without issue for some reason.

Yes, there is a solenoid that locks out reverse unless you are below 4kph. The PCM powers up the solenoid to allow reverse to be selected. You can force past it (as you have found but obviously not ideal)

Solenoid get power from the wiring to the reverse light switch and is earthed via the pcm. The pcm sees the clutch pedal switch input and if below 4kph earth's the solenoid.

1.check the clutch pedal switch wiring

2.check the solenoid is plugged in.

3.if the car has been tuned,the tuner hasn't recycled an auto/5spd manual tune file.

I got the multimeter onto the cable that plugs into the solenoid. It's around 12v when ignition is on, and changes by about 0.3volts when the clutch is pressed. Does this confirm that things are working otherwise and it's a faulty solenoid, or should I be checking something else?

Thanks.
