DTC Event Comment Latched
211 Power Cycle • This Help Message is issued at each power-up. This
serves to indicate which messages have been recorded
in Logged Help since the last power-up event.
No
33427 Anti-Stall Valve
—Open Circuit
• Anti-stall digital output was open-circuit. This fault
may be caused by improper wiring or a control
module issue.
• The desired current is greater than 250mA, but the
actual current is less than 75mA
• Normal operation will resume when issue is resolved
Yes
33426 Anti-Stall Valve
—Short to Battery
• The anti-stall digital output was shorted to battery. This
fault may be caused by improper wiring or a control
module issue.
• The desired current is 0mA and the digital output
driver’s diagnostic feedback is low
• Normal operation will resume when the issue is
resolved
Yes
33428 Anti-Stall Valve
—Short to Ground
• The anti-stall digital output was shorted to ground. This
fault may be caused by improper wiring or a control
module issue.
• The actual current is greater than 200mA, PWM is 95%,
and the digital output driver’s diagnostic feedback is low
• Normal operation will resume when issue is resolved
Yes
441 Battery Voltage Too Low
—System Shutdown
• Battery voltage is less than 8.0V. The control module
may be unable to regulate proper output current.
• The CM will continue to regulate the Anti-Stall Valve,
but higher currents may not be possible
No
442 Battery Voltage Too High
—System Shutdown
• Battery voltage is greater than 16.0V.
• The CM will continue operation, but extended periods of
time above this threshold may cause thermal shutdown
of the CM’s primary regulator
Yes
998 EEPROM Failure • The control module detected an issue with the non-
volatile memory used to adjustments. Verify all settings
using the JLG Analyzer.
• Since no critical settings are maintained in EEPROM,
the CM will continue operation
Yes
