Proportional output P7, which controls the starter interlock relay K52, takes
current which exceeds or goes below the given limits. Short circ uit or

Supply voltage of clutch and gas pedal position sensors is not within given
limits (4,5…5,5 VDC). Probably wires in short citrcuit.

A326 A1A1/1
A1A1/2
Control unit supply voltage not within limits 10,5…17,0 VDC. Battery damaged
or poor contacts or short circuit in wires. Check the alternator.
Low battery voltage causes the oil pressure drop and damages the multi---
disc clutches of the tractor shuttle and DPS.

A351 A1A7/1 Signal from rear clutch pedal position sensor B1W below 0,3 VDC or over 4,7
VDC. Sensor wrongly fitted or sensor/wire damages. This fault code appears
only when the seat is turned backwards.

d116 A1A5/9
A1A5/10
DPS up--down push buttons (S23) are active simultaneously. Push buttons in the
lever knobs may be in short circuit. The fault code can also appear, when the service
modes (FI--F III) are activated.

d117 A1A8/1
A1A8/2
Forward (S40) and reverse drive direction (S41) are active simultaneously. Shuttle
lever switches may be in short circuit.

d118 A1A8/4
A1A8/5
Both PTO speeds are engaged simultaneously. PTO lever switches (S28/S29) may
be in short circuit.

d123 A1A8/8
A1A8/1
A1A8/2
Front parking brake and one or both shuttle directions engaged simul-

PTO start switches (S25, S1A, S2A) in the cab and in the rear mudguard are simultaneously
active. Probably short circuit or switches have been stuck.

d152 A1A2/8
A1A2/7
In the reverse drive controls F and R directions active simultaniously. Shuttle
lever switches probably in short circuit. This fault code appears only when the
seat is turned backwards.

A1A2/6
Front and rear clutch pedal limit switches S9 and S2W active simultaneously . Probably short
circuit in the switches or switches have been stuck.
