Possible reason
•
Check that all supply voltages on
D1 are present, refer to page 110**.

If CAL 28 occurs again or remains
displayed: the ROM containing the
program may be defective.
Replace the software (IC's I72, I66
and I74) on D1 ; refer to page
110**.
•
If the error remains after replacing
the software, D1 should be
replaced.
•
Enter the cause and the error
message "CAL 28" in the service
protocol.
•
The single tank is missing or the
cable harness is 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).
