2010 Liberty Trac and ABS lights

Post by luznit » Thu Dec 14, 2017 11:37 am

I recently installed a Pioneer Avh-4201NEX with a Maestro RR into a 2010 Liberty( non amplified). After the install the Trac, ABS, and ESP lights come on interminently. I have disconnected the CAN wires at the OBD2 and it cleared the problem.

Generally, the only time we see errors like that is if the OBD2 connections are not solid. If there is additional resistance on the line due to a poor connection, t-tap, etc, that will cause error lights to show up on the cluster.

The connections are soldered, I redid the connections as well. The only thing I haven't tried is cutting out the 2 pin connector and hardwiring those connections. Ill give that a shot

Any update on a cause for this?
I just installed a Pioneer AVIC-W8400NEX in my 2010 Liberty Sport, non-amplified and an having the same issue.. I used the HRN-RR-CH1 plug and play harness that plugs directly into the OBDII socket. My ABS, ESP, BRAKE lights will come on randomly. I connected an ABS scanner, which required unplugging the maestro, to scan the ABS computer for the error codes and when I did all of the warning lights went off and the scanner says no DTC's found. It all started after the install, I've double checked my wiring and everything seems ok.

When this happens, I recommend hardwiring to the back of the OBD2 connector and making a solid, soldered connection. As I stated above, a poor connection at the OBD2 is really the only thing that causes behavior like that.

I forgot to update, on my Pioneer head unit I changed the setting under ODBII communication to Enable on demand and I haven't had any further issue
