Suspension Fault

[Lockee]

05 HSE v6 270k shortened rods. No history only had for 10k

Air leak at rear. Discovered hose out of compressor had a hole. Fixed

Compressor is only 2 years old. Win

No leak but after starting car. Fault comes back up. Relay is ok.

Have I missed a reset or where to look next?

Thanks

Yeah may need a reset, i think i read than disconnecting both + and - leads from the battery and touching leads together will clear the faults.

If you do that reset I am pretty sure you have to wait till the car has gone to sleep. You need to wait till the P light has gone out on the dash.

Anyone close by that has a code reader to check and clear the fault ?


Cheers Ean

Hard reset done but no change. Suspension fault and car on bumpstops

[Graeme]

It may help if you describe what happens from when the engine is started giving an indication of the time intervals between activity.

Car starts no lights on after 15 seconds suspension fault comes on. Pump doesn’t appear to start

[Graeme]

The pump not starting will definitely cause a fault.

Did you remove the pump?
Is the electrical connector at the pump firmly fitted to its mating connector?
Is the 5A suspension system fuse in the engine bay fuse box OK?
Can you determine if the pump relay is operating for the 15 seconds then detect it dropping out?

Thanks Graeme

Pump was working but shutting off when first gust of air was released on start up. Didn’t disconnect compressor. Checked underbonnet relay

[Lockee]

Will check the fuse now. Sounds like relay clicks in. Fully on bump stops now

[Graeme]

The suspension will be dropped to the bump-stops if the vehicle can't be raised to normal height quickly enough but 15 seconds indicates something else wrong such as a totally blocked dryer causing the motor to draw excessive current. If the pipes at the rear are disconnected then the pump should run for longer than 15 seconds if the dryer is not blocked.

Found it 60 amp relay had a 50 amp relay that had burnt out

[Lockee]

Suspect dryer as stated above.

Lots of wrong rated fuses from previous owner

[Graeme]

So is the suspension up now?

[Lockee]

Nope even hard reset keeps the red suspension warning light on. Will replace fuses and reset again tomorrow

[Lockee]

Burnt out compressor
