Reserve mode fails with 4 flashing lights

Question

EVO-ONE, 04/2022, SN: 002B04 271047

2009 Subaru Forester, manual transmission

Remote Start program: 0.44 for Omega Remote OL-RF-42-SST

Customer had a battery issue previously which lost remote programming. After resetting and reprogramming the remotes to enable reserve mode by pressing the remote start key while running in neutral with e-brake on and foot brake released, the parking lights flash 4 times and will not enter reserve mode/keep the vehicle running. I believe this relates to the tachometer signal.

This system worked for several weeks prior to the battery issue.

Is the tachometer a "taught" signal, is this a wiring issue, or some other issue? Any assistance would be appreciated.

Answer 1

4 flash sounds like valet mode. Turn ignition on, press the valet button 3 times, then turn ignition off.

Comments

The 4 flashes was while the vehicle was running, valet mode was confirmed off.

Odd behavior started happening shortly after this and the immobilizer would not give a valid code to the ECU (engine died after 2 sec of running).

After disconnecting the vehicle battery, the positive and negative leads were contacted for a minute, then replaced on the battery. Everything functioned normally after this aside from programming aftermarket remotes. Reserve mode functioned with foot brake-hand brake-release foot brake. OEM fob could remote start with lock-unlock-lock.
