Default AHC light blinking 1999 Lexus LX 470

How do you stop the AHC light from blinking when the system is converted to non hydraulic system (Strutmasters/Landcruiser shocks and coil)?
Also, is it possible to replace only the front AHC shocks with standard shocks and leave the rear AHC shocks in place?

No idea on how to kill the lights...but it's doable. I'd call sleeoffroad.com and ask.

AHC will report trouble codes for both front shocks and only God knows what else. If you already have Cruiser bars and shocks in the front, I'd add Cruiser springs and shocks to the rear and you're done.

Disconnect the connectors off the AHC ECU and you can pull the 50A AHC pump fuse under the hood and the AHC B fuse in the drivers side footwell. Leave the AHC IG fuse installed or you'll get steering angle sensor problems. All four AHC Shock actuators must be replaced (they aren't shocks but throttled actuators with the damping controlled remotely at their respective damper assemblies) as do the AHC torsion bars and coils. AHC torsion bars and coils are rated at approximately 60% of conventional LC 100 torsion bars and coils and therefore aren't fit for purpose without the systems hydraulics.

Thanks for the reply. I have read horror stories about getting the warning light off (pulling fuses and such) but I will research that more before I do it.
