Table 2
Warning Codes    
Display     Warning     Corrective Action    
Wire Pitch X (X is a number from 0 to 9)     Wire nut is installed too loose by X pitch. X can be a positive or negative number. Turn clockwise.     Tighten the accelerator cable by the displayed pitch. Perform the calibration again.    
Wire Pitch X (X is number from -9 to 0)     Wire nut is installed too tight by X pitch. X can be a positive or negative number. Turn clockwise.     Loosen the accelerator cable by the displayed pitch. Perform the calibration again.    
01     Insufficient high idle     High idle is less than the specified value due to malfunction of the engine, incorrect installation of the governor cable, poor fuel, etc. After the engine has been inspected for a malfunction, reinstall the cable and perform the calibration again.    
02     Incorrect installation of cable     Reinstall the cable and perform the calibration again.    
03     Excessive low idle     Low idle is more than the value specified due to a malfunction in the engine, an incorrectly installed governor cable, etc. After the engine has been inspected, reinstall the cable and perform the calibration again.    
04     Excessive hysteresis     Ensure that the cable is adjusted correctly. Reinstall the cable and perform the calibration again.    
05     Unstable high idle     High idle is unstable due to a malfunction in the engine, an incorrect installation of the governor cable, etc. After the engine has been inspected, reinstall the cable and perform the calibration again.    
06     Unstable dial speed     The speed for the dial setting is unstable due to a malfunction in the engine, an incorrectly installed cable, etc. After the engine has been inspected, reinstall the cable and perform the calibration again.
