After 3 days at a Holden dealer - with them not having any idea, I’d appreciate any help to find a solution, as it’s driving me crazy!
Some background:
Coming out of lockdown (during which my ‘16 SSV-RR was rarely driven) I’m getting a lot of “Service ESP” messages on the dash. I also get “Service Brake Assist” (and other similar messages) and my gauges (speedo, tacho, etc.) sometimes “drop out”.
Click here for a short (15s) video showing the problems. (Filmed by my daughter whilst I’m driving - in case anyone is wondering!)
So, I’ve been researching. Battery and Injectors seem to come up frequently. Since the car still runs perfectly well, I don’t think it’s the injectors. I measured resistance, and all were ~12.3Ω. Perfectly in-spec.
Given I was on the original battery, and a prior service mentioned it was looking weak, I thought it’s definitely time to replace. So I did. Charged before fitting, and left the terminals disconnected overnight to clear any codes. Also checked as many fuses and ground wires as I could. (Car has done < 40K km’s and still looks brand new inside and out.)
Anyway, obviously the problem did not go away.
So, I’ve been playing around with GDS2 (still figuring it out), and first thing I did is check the codes, and sure enough there’s lots, but they’re all “Communication lost” with various modules. (Click here for Report.)
I’ve noticed that it always seems to start playing up when I”m braking, but not until warmed up. Had my son keep an eye on brake module parameters to try identify anything unusual whilst I drove. Turns out I can review the data, and here’s what it looks like:
I’ve noticed that when I start-up, Battery Voltage starts out 14V+. (Green line.) After a few minutes, it drops down to low 12’s. At the point circled “1” I get an error (brown line). I’ve noticed that after braking (gaps in blue line) I often get a voltage drop (2a, 2b, 2c). The error happens on the first brake application after the voltage has dropped to the 12’s. Although it doesn’t show, I’m wondering if I had a drop like in the earlier observations, but the system has become too low to operate normally and hence the error?
Sorry for the long post, but I’d welcome any thoughts/suggestions at this point!
