Manual trigger ok module trigger not

I have already accomodated for resistor.  Ground testing verifies that a 1.5K resistor works, However daniel2002p you say that a 1k works for you.

In either case I cannot see how this helps me.  Manual ground testing the (external) rely trigger wires functions but the command modules (-) 200ma output on the trigger does not work properly.  In either case I can hear and feel the relay switch.

Could the command module (-) 200ma pulse be too short?

basic relay setup.  #87 ground (car chasis), #85 12V,  #86 trigger (ground testing works , or Module signal not work) #30 to unlock through 1.5K resistor.  Just as the wiring diagram tells you. (2001 Malibu)

Same for trunk except for the resistor. Lock already works.

I can hear and feel both the relays switch when using both the module triggers and ground test trigger,  but the desired function does not work for the module trigger.  The module is supposed to provide a 1 sec. 200mA ground pulse for both unlock, lock and trunk acording to the install manual.  AND YES IT SAYS GROUND in the manual.

I have even checked function with a multimeter and with both types of signals the voltage drops are virtualy identical, except one works the other doesn't.

I am wondering if the pulse from the module is not long enough or strong enough to provide good contact in the relay switch.  This seems odd because in many cases, simply the module signal can sink enough current without even using a relay in many cars.

I'm calling Commando to get to the bottom of this.

NOTE: After the first sign of problems I replaced the Module system ground with a heavier gauge wire with no change.

ALL ground are directly to car chasis and each has a seperate lead.
