Wht/red = 12.3v
Green = 5.01v
Blk/grn = 0.01v
Vio/wht = 5.01
Blk/org = 0.03v
Org = 0.03
No current to the secondary circuit.
Computer plugs 22pins 26pins
Wht/red = 12.19v
Green = 0.41v
Blk/grn = 0.01v
Vio/wht = 0.73
Blk/org = 0.00v
Org = 0.75v
Observation:
There are variation on the reading of pins.
Check grounds: i'm going to check the grounds again.
Positive cable from battery to inside of the passengers cabin, passing through the firewall by a hole on metal without protection. The cable is damaged and have contact with the metal of the firewall. I repair it
The relays are working properly.
At this time the check engine show only two codes #35 and #41. I make the repair for the other two #4 and #9.
I'm going to change the coil, because for me is strange that there's no spark at the spark plugs.
I'm going to repair the other two codes, but i'm going to change the coil.
It's that or for the readings of voltage I made there something wrong with the ecu, ecm?
Is the same diagram for the manual transmission engine?
If you have any other suggestions, i'm open to receive it. My mind is open for other points of views. I'm learning.
Thanks.
