The Toyota service manager, Andrew, rang while we were out. He'd asked about Elmer's after market immobiliser system. Nick and I answered as best we could.
Andrew confirmed Nick's thought regarding Elmer's problem but at that stage the solution was still not clear.
We were only back at the cabin a few minutes when we received another call from Andrew. Elmer was fixed and ready to be collected! Even better the repair was only $154!
Understandably, there was huge relief all round!
Nick and I walked across to the NRMA depot. Andrew greeted us. He handed over a small part - a fusible link - which was the cause of Elmer's problems. The link is designed to short if there is a wiring issue. Elmer's hadn't fused but the connection wire had worn through and that had shut-down everything.
