so i was washing my car the other day i went to go start it and when i turned the key nothing turned on the clock wasnt even working so i thought no big deal i charge the battery it started up sounded crapier than normal but it worked so then i come out the next day and its completley dead again ive had a code 26 for a while now so im thinkin it has something to do with that quad driver code can some one help

 

code 26 (quad driver output fault) is almost never the actual quad driver within the PCM itself; it is almost always something hanging off that circuit. This circuit is used to simultaneously monitor the status of

SES circuit
cooling fan relay
A/C clutch
Canister purge solenoid
EGR solenoid
Coolant Hot light
Upshift/Shift to D2 light
Speedometer Cutout

If any one (or more) of these have an issue, you'll get a code 26. EGR solenoid and cooling fan relay are most likely and easiest to check.

As for dead battery symptoms -- check battery cables (connections and integrity) at the battery, the hot lead to the starter, and the ground off the battery to the frame.

It also may just be time for a new battery.....
