Shift lock system not working, need help to locate the problem


Recommended Posts

Hi guys!

 

i had several years with the shift lock system not working properly, some times unlock when i depress the brake pedal; often does nothing and then i have to manually unlock it (pressing the button)

 

but now, i just decide... i wan tot pursuit the problem and fix it! (with your help, of course)

 

i just disassembled the shift lock plastics.. and i used my multimeter to figure it out that there is no voltage at the solenoid when i press depress the break pedal

 

so following back the chain.. i guess I should now test the solenoid relay.. am i right?

 

Where can i locate it?

These are old cars. I'm not sure of the wiring, but I would start with the switch on the brake pedal. Maybe it's wired to the brake light switch?

Hi!

 

the brake pedal wiring is ok, there is only one switch, so i guess any info/action the ecu need which involve the brake pedal would come from that switch, and brake light is working, so i assume brake pedal switch is oke.

I would maybe start by checking the signal from the switch on the appropriate wires, or from lock out back to the switch.

 

Or convert to a manual transmission. ;)
