FAULT CODE
FAULT
CONDITION DESCRIPTION
*NOTE: See Table 4.00-4 for cylinder identification.
IMPORTANT! The following critical ESDs (shown in bold in table above) will prevent post-shutdown func-tionality from occurring:
• ESD222 CUST ESD
• ESD223 LOW OIL PRESS
• ESD313 LOCKOUT/IGNITION
• ESD532 COOLANT PRESS LOW
To clear a critical ESD (to allow a restart or enable recirculation), you must cycle either of the E-Stop switches at the engine.

SHUTDOWN
CONDITION DESCRIPTION
ESD212 CRANK MAG PICKUP ECU detects fewer crankshaft pulses between camshaft pulses than it was expecting
ESD214 CAM MAG PICKUP Too many crankshaft pulses are identified between cam magnetic pickup pulses (or no cam magnetic pickup pulses are detected) ESD221 OVERSPEED ENGINE Engine overspeed; engine reached ESM upper limit
ESD222 CUST ESD Critical ESD – Shutdown has been triggered by an external action; by customer equipment
ESD223 LOW OIL PRESS Critical ESD – Oil pressure below lower shutdown limit ESD224 KNOCK ### CYL Cylinder was at its maximum retard timing due to knock *
ESD231 OVERCRANK Time the engine has been cranking has exceeded a maximum
crank time
ESD232 ENGINE STALL Engine stopped rotating independent of ECU which did not receive a signal to stop
ESD251 OVERSPEED DRIVE EQUIP Customer-set overspeed limit exceeded
ESD312 OVERLOAD Engine was overloaded
ESD313 LOCKOUT/IGNITION
Critical ESD – Lockout or E-Stop (emergency stop) button on the engine is “ON” or there is a power problem with the IPM-D module (either it is not powered up or the internal fuse is blown)
ESD315 HIGH IMAT Intake manifold air temperature above upper shutdown limit ESD333 HIGH COOLANT TEMP Engine coolant temperature above upper shutdown limit ESD335 KNOCK ABS THRESHOLD A knock sensor output value exceeded an absolute threshold
programmed to ECU
ESD424 HIGH OIL TEMP Oil temperature above upper shutdown limit

ESD551 UPDATE ERROR/FAULT Update error/fault
ESD553 SECURITY VIOLATION Engine type that is factory-coded in the ECU does not match with the downloaded calibration
ESD555 INTERNAL FAULT
Serious internal error in ECU; call the factory; do not attempt to restart engine. Contact your local Waukesha Distributor for technical support.
