ABS & TC Lights on

**ezyrama** · 8th September 2019, 11:36 AM

Morning all
I was out at Canungra delivering stuff to the fire fighters yesterday and I pulled over to take a call. I felt the ABS kick in as I stopped on loose gravel, but when I took off again, the ABS & TC lights came on and now wont extinguish. Stopped again, pulled the ABS fuse under the seat, and the handbrake light then stayed on. I put the fuse back in and drove home. Handbrake light is off today but ABS & TC lights are still on. Any ideas pls.

If you’ve got a nanocom it might tell you something ...on td5’s somtimes the sensors in the hub wiggle up out of there hole and you can clean them and firmly seat them back..worth going round with a multimeter set to ohms and unplugging each sensor and checking the resistance[it may show one lower than the others if cleaning doesn’t sort it, you may have to get the fault wiped of the ecu after or it may still light up the abs/tc lights...on a td5 it doesn’t
Worth checking and cleaning all the connectors back to the abs modulator

Thx Mark, I don’t have a “nanocom” but I have 2 different scan tools. Both are detecting no faults logged. I’ll check and clean the abs sensors and see what I can find. Don’t suppose anyone knows the resistance of the sensors?

Nah not really , I know d2 sensors are from 950 ohms to 110 ohms, though td5 defender ones are a different sensor...I get from 925 to 950 ohms on the defender, so I’d think the puma’s would be similar ....if you can’t scan the abs ecu you won’t see faults..nanocom let you scan the Waco abs box.
I’d say if you pull the 4 plugs between hub and modulator and there all similar then there fine..there a barrel shaped plug about 3 inches long..likley sitting near the guard in the engine bay and tucked up high in the rear
