Mikeb......do you have an email address to post in your profile or profile signature????

thanks kevin this will help alot.I cleared the codes for now to see which one returns.I will get back to you thanks again

Code 77:

OxygenSensorInputHigh
O2 sensor SECM driver signal is shorted to power

Check if O2 sensor is shorted to +5VDC or Battery.
O2 (SIGNAL) PIN B to SECM PIN 3
(AFRTrimValveLowerDC fault should also occur)
Verify O2 sensor heater circuit is operating by measuring circuit resistance (2.1Ω +/-0.4Ω)
O2 PIN C (HEATER GND) to PIN D (HEATER PWR)

Cose 42:

EST1Low
Coil driver signal low or under- current

Check coil driver wiring and connector for shorts
SECM PIN 7(EST1) to COIL PIN A
Verify GND on COIL PIN B Verify GND on COIL PIN C Verify GND on COIL PIN D Verify +12vdc on COIL PIN E
To check the Smart Coil internal circuit disconnect the coil connector and measure the resistance from pin to pin

got two codes 77,42 do these apply

re-up
see my previous corrected post

THIS IS FROM THE BOOK FOR TWO DIGIT CODES.....
Possible you may read three digit codes.......

Displaying Fault Codes (DFC) From SECM Memory/

To enter code display mode you must turn OFF the ignition key. Now turn ON the key but do not start the engine. As soon as you turn the key to the ON position you must cycle the foot pedal by depressing it to the floor and then fully releasing the pedal (pedal maneuver). You must fully cycle the foot pedal three (3) times within five (5) seconds to enable the display codes feature of the SECM. Simply turn the key OFF to exit display mode. The code list will continue to repeat until the key is turned OFF. An automatic code display feature is activated if a foot pedal fault condition exists. This feature enables the service technician to view the fault codes by turning the key to the ON position, if a foot pedal malfunction is preventing the retrieval of the stored fault codes from the SECM.

Reading Diagnostic Fault Codes:

All MI-04 fault codes are two digit codes. When the fault codes are retrieved (displayed) the MIL will flash for each digit with a short pause (.5 seconds) between digits and a long pause (1.2 seconds) between fault codes. A code 12 is displayed at the beginning of the code list.
EXAMPLE: A code 26 has been detected (ETCSticking) and the engine has shutdown and the MIL has remained ON. When the codes are displayed the MIL will flash one time (1), pause, then flash two times (2). This identifies a twelve (12), which is the beginning of the fault list. It will then pause for 1.2 seconds (long pause) and flash two times (2), pause, then flash six times (6). This identifies a twenty-six (26), which is the ETCSticking fault. If any additional faults were stored the SECM would again have a long pause, then display the next fault by flashing each digit. Since no other faults were stored there will be a long pause then one flash (1), pause, then two flashes (2). This identifies a twelve meaning the fault list will begin again.

Clearing Fault (DFC) Codes:

To clear the stored fault codes from SECM memory you must complete the reset fault pedal maneuver.
CAUTION:
Once the fault list is cleared it cannot be restored.

First turn OFF the ignition key. Now turn ON the key but do not start the engine. As soon as you turn the key to the ON position you must cycle the foot pedal by depressing it to the floor and then fully releasing the pedal (pedal maneuver). You must fully cycle the foot pedal ten (10) times within five (5) seconds to clear the fault code list of the SECM. Simply turn the key OFF to exit the reset mode. The code list is now clear and the SECM will begin storing new fault codes as they occur.

thanks kevin will try that

AND.....To CLEAR CODES on a WOODWARD fuel system....turn the Keyswith ON....after THREE(3) SECONDS......pump the Accel pedal TEN(10) TIMES WITHIN TEN(10) SECONDS.....PEOPLE need to read previous posts to a thread!!!

This truck is a LPG Gas truck if it is a C32 series...it probably has the Woodward fuel system in it.....

i will check it out , it's hard to get the drivers off the lift to work on these things

Mike
i'm sorry i was having a major brain malfunction when i made this post, i hope i didnt TOTALLY confuse you , i was reading another post on an electric truck and got crossed up.
talk about a major brain fart....
hits himself upside the head

thanks kevin for posting that i was truely not trying to mislead mike, judging from your caps you seem a bit upset and that caught my attention ;o)

mod#c32cl ser#c232l-0631-9664-kf. I order service manual but has no computer diag. in it?

look on the dataplate
write down the FULL model and serial number
come back here and tell us what it is
otherwise nobody can help you

were can i get service manual for this

yes it is a woodward system lift runs fine.all gauges are fine

Only way anyone is going to be ale to help is if you give MORE information on what type of fuel and control system is in it...saying that it has a hydrostatic transmission dosent do any good....is why I asked if it had a Woodward regulator/Vaporizor and air mixer.......other that that everyone will be taking a WAG.....

come on know body can help me with this

not woodward it has hyperstatic forward/rev any other ways ? also how can i pull codes
