LENZE DRIVE WE HAVE LENZE DRIVE BUT PROBLEM IS DRIVE GIVE US ERROR UNDER VOLTAGE SO I WANT TO TAKE HELP YOU SO I HOPE YOU HELP US I DONT KNOW WHAT I CAN DO IF YOU HELP SO I WILL BE THANKFULL TO YOU. I M WAITING FOR YOUR E-MAIL PLEASE SEND US DETAILS VERY SOON BEST REGARD KAMRAN SAHAB THANKS MY FRIEND

This is an internal PCM failure code . The only test is to clear the code and if it resets to replace the PCM. this is covered by warranty for 8 years or 80,000 miles . So if you are under this its a free repair under warranty.

P0685 error - ECM/PCM Power Relay Control Circuit open

Hope helps.

your selector switch is bad i hope this helps please give good rating thank you

under the hood in your fuse box there is a fuel relay, it should click when the ignition is turned on, is it getting spark, or is it fuel. Hope this helped

THAT SOUNDS LIKE LOW VOLTAGE. PUT A VOLTMETER ON THE BATTERY WHILE TURNING THE KEY IN THE START POSITION. IF THE VOLTAGE DROPS BELOW 8 VOLTS, THAT IS TOO LOW. BATTERY NEEDS TO BE CHARGED OR REPLACED & TERMINALS CLEANED. IF IT STARTS CHECK THE CHARGING SYSTEM. MOTOR RUNNING, VOLTAGE AT THE BATTERY SHOULD READ 13.90 TO 14.90. IF IT IS TOO LOW GET THE ALTERNATOR TESTED.

the newer gms have kind of a curcuit borad type lenz assembly,i took mine apart and put screws in it to make it thighter and it worked ,check make sure you getting voltage to the connector put on 4 way flashers and tail light on ,you can buy cheapper assembly at surefit aftermarket if you dont want to try to fix it i wish you could fit the old type lense ,they were fine for many years

Does the car have DRL ? daytime running lamps Do you know how to test automotive electrical circuits using voltage drop testing . Do you know how to use a DMM - digital multimeter ? How to read an use a wiring diagram to find testing points in an electrical circuit ? IF not you probably won't be able to find the problem .

You will need wiring diagrams http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on lighting ,then under subsystem click on headlamps . Click the search button then the blue links . Check B+ voltage to the fuse's ,check the headlamp relay in the left insturment panel junction block . Do you know where that is ? Your owners manual should say .

check in your owner manaul to see which fuse it is i know its all on one fuse for horn interior light check in your book under fuses then find out which one it is and the fuse panel is under the dash or in engine area on fire wall

u have to pull the front bumper assembly off the sit in bracket assembly behind the front clip

I would have generator checked for output.If that checkes good check for tight battery cable connections.Also there is a ground under the rear speaker carpet that may be loose or broken that would cause that concern.Hope this helps

have you checked the voltage at the battery terminals while the car is running,it should be about 13-15volts, 15volts absolute maximum and no lower than 13volts minimum. ideally voltage at battery should be 14.8 maximum when cold. when the car is at operating temperature it should be roughly 13.8volts at battery. try doing a simple load test ,turn on headlights with high beam on,turn on air con or heater,internal light, even hazards.if you have under 13.8 volts at battery give it a rev to about 2000 rpm and watch for increase in voltage at battery terminals using a multimeter. if voltage is lower then you must have voltage drop somewhere in your wiring,eg; wiring harness to all your sensors,relays etc. check all fuses,fusible links(usually braided looking wire about 100mm long) also check the back of the alternator with multimeter( positive point on alternator and negative on multimeter to a good earth on body or motor eg; a nut or bolt nearby.if you dont have a multimeter and or dont know how to use one, you can buy them pretty cheap from a spare parts joint with instructions for under $20:00,you can find tutorials on internet for free. hopefully this has been some help,by the way make sure you dont flatten ur battery too often,discharging a battery too much can kill it,cheers and good luck!
