** SEE NEW POST FOR UPDATED ISSUE **
Hey all,
Recently bought my 2nd jza70, pps was working fine, the dash was severely cracked, so i changed the dash, whilst i was there i replaced all the leds on the cluster with regular bulbs since it lit up poorly (and lightly polished the plastic due to scratches, apart from that, didnt touch the cluster) reassembled everything and now the power steering is set to hercules.
Have done some quick TS using the TRSM/TEWD, theres a good +B, a good ground, and a good solenoid (no continuity to earth on either pin and measuring roughly 8.4ohms, within spec)
which leaves me with 'is the pps ecu getting a signal,' evidently not, i plan on pulling the cluster out tomorrow, i am going to test for continuity from the cluster wire to the pps ecu connector, pink wire, blue cluster connector (pin 7), if that checks out ok, where do i go from there? (if the wire is broke I am happy to run my own wiring, but thats assuming the wire is broke.)
Is the speed sensor in the cluster removable? fixable? (does anyone have a pic of it?????) i know daddio (off supraforums australia) was saying the a80 suffers from dead tracks/poor joints, is this common on the a70 too (iam handy with an iron, would just like to know before ripping into it)
as quoted below, i can bridge red/blue & pink wires on the a80, can i do the same on the a70, using the wire on the other side of the speed sensor? (which i believe is the brown wire on the same blue connector)
Failing all this Ill probably make an adjustable power supply and feed it X volts until I am happy with the feel, but would like to fix the stock system if possible.
Its the only thing thats stopped functioning post dash changed, so I doubt ive left a connector unplugged, but will be checking all those connectors also.
Yes I've searched, theres no real info on the speed sensor itself.
this is a JDM jza70 running a r154 from factory, RHD model being JDM (I am in australia, hello!)
cheers for any insight.
And heres the quote from supraforums australia

PPS ECU gets a speed signal from the odo (pink wire) Odo pass through is known to occasionally fail on the A80 (solder joints on the odo PCB and dead tracks)
As a test, try bridging the red/blue and pink wires behind the odometer with a temporary Scotchblock connector to see if this fixes your PPS issue...takes maybe 15 mins, and is fully reversible.
