2001 Toyota Highlander tach signal problem

0 votes
I just installed an evo one in a 2001 Highlander. Vehicle runs for about 8 seconds then shuts down and flashes the parking lights four times which means no tach signal. I have programmed the module to tachless. I set tachless sensitivity -3 because starter did grind with default setting. I have reflashed the module a couple of times and double triple checked all my wiring what am i missing. Why would it flash no tach signal if I have it set to tachless mode option 20 selection 2.  Please help I have no idea where to go from here

Hello,

 

Tachless is based on the charging system. i would meter the battery when remote starting and observe the voltage.

If it does not climb to roughly 14 then stabilize I would verify how the ignition switch is wired. A ignition circuit is missing.

 

Best regards.
