Possible reasons and advice
•
Check that all supply voltages on
D1 are present (see page 110**).
•
If CAL 28 reoccurs or remains
displayed, the ROM containing the
program may be defective.
Replace the software (IC's I72, I66
and I74) on D1 (see page 110**).
•
If the error remains after replacing
the software, replace D1.
•
Enter the cause and the error
message "CAL 28" in the service
protocol.
•
The single tank is missing or the
cable harness has been incorrectly
connected.
•
Check that connection K9 on D1 is
connected.
•
Check for possible damage in the
main cable harness between D1
and the single tank. Measure K9:
13-4 and move the arm and single
tank while the connections are
being measured (see page 140**).
If damage is detected, replace the
main cable harness (both cables)
(see section "Replacement of the
arm cable harness").
