1.60 CHASSIS SENSOR SUPPLY OUT OF RANGE HIGH

Flash Code: 9-9
Chassis sensor supply out of range high. The supply voltage for steer angle sensors is above the expected range. A power
cycle is required.
Note Pretest Instructions
1.60.1 Cycle power
1-60
Test
Is there continuity between terminal 1 of the 2
position chassis power connector [X263.1]
and the ground bus connector [X009]?
Do the faults BOOM ANGLE SENSOR #1
COMMUNICATIONS FAULT and BOOM ANGLE
SENSOR #2 COMMUNICATIONS FAULT both
show in the fault log before a power cycle?
Is there a short to ground on socket 5 of chas-
sis module J1 connector [X229.5.soc]?
Is there a short between pin 4 and pin 5 of the
chassis module J1 connector [X229.4.pin
X229.5.pin]?
Is there a short between pin 4 and pin 5 of the

Upper Swivel connector [X083.4.pin
X083.5.pin]?
Is there a short between socket 87 of the
Chassis Power Relay connector
[X266.87.soc] and socket 85 of the Chassis
Power Relay connector [X266.85.soc] or the
negative side of the battery [X117]?
Is there a short between socket 30 of the
Chassis Power Relay connector
[X266.30.soc] and socket 85 of the Chassis
Power Relay connector [X266.85.soc] or the
negative side of the battery [X117]?
Test
Does fault clear?
