ok kev
you're gonna make me direct quote the complete paragraph and this comes straight from hyster online in the H45-65 XM (H177 prefix serial) manual.
and i quote:
Using a Diagnostic Jumper to Diagnose the ECI System
If you do not have access to a laptop computer, it is still possible to access the diagnostic trouble codes stored in the memory of the Spectrum system ECM using a diagnostic jumper and the malfunction indicator lamp. With the key OFF, connect the diagnostic jumper to the DLC located near the ECM. The jumper will connect diagnostic pins A and D. Turn the ignition ON but do not start the vehicle. The malfunction indicator lamp (MIL) will begin to flash.
The MIL displays three digit codes by flashing the first digit, pausing, then flashing the second digit, pausing, and then flashing the third digit. There will be a long pause between codes. For example, a code 143 would be one flash followed by four flashes followed by three flashes.
The MIL will first display a 166 three times. Code 166 indicates that the ECM based diagnostic routines are functioning. Then, any Diagnostic Trouble Codes stored in memory will display three times each. The MIL will then start over with the code 166. If the vehicle is started while the diagnostic jumper is in place, the MIL will flash rapidly.
Diagnostic Trouble Codes may be cleared from the system ECM memory by moving the ignition key to the OFF position and removing the (F2) system battery fuse for at least 15 seconds.
NOTE: This will erase all of the memory in the computer including the adaptive learn.
not sure what manual you're looking at
enlighten me please? where are you seeing this 116 at?
but the part that is really confusing is he says it has a GM engine in it and in the GM section there is no option that i can find for a diagnostic jumper, it only shows the 8 prong plug for the OBD scanner and that diagnostic initiate check code is a 12 that flashes up. And the only DTC codes showing are 2 digit codes.
At this point i'm as stumped as he is but i'll keep checking service grams etc to see if i can find anything.
am i missing something here?
