INTRODUCTION

The purpose of this quick-reference guide is to provide information
to help users in the troubleshooting routine and elimination of some
faults detected on the aircraft through rest procedure.

This guide does not cover all the messages/faults that may be
detected on the aircraft. If the message/fault is not given in the
quick-reference guide, refer to the FAULT ISOLATION MANUAL.

The guide is organized in a three-column table, disposed as
follows:
• ATA column: Gives the ATA number for the related
fault/message.
• MESSAGE/FAULT column: Gives the messages/faults,
alphabetically ordered.
• MAINTENANCE ACTION column: Gives the corrective
action (PROCEDURE). It may also inform the
EFFECTIVITY and/or FAULT CONDITION.
• “IS THE FAULT REMOVED?” column: Gives the results
of the procedure indicated in the Maintenance Action
column.

When the reset procedure does not remove the message/fault,
refer to the FAULT ISOLATION MANUAL and do as follows:

1. On the “CAS MESSAGE LIST” or “OBSERVED FAULTS
LIST”, in the front matter of the chapter, find the related
FAULT CODE (FAULT CODE column).
2. Go to the “FAULT CODE INDEX”, and use the related
FAULT CODE to do a check for correlated CMC
messages:
(a) If there are correlated CMC messages, in the
“CORRELATED MAINTENANCE MESSAGE
CODE” column, look for the correlated
maintenance messages on the CMC (AMM
TASK 45-45-00-970-803-A/200) to find the task
that you must do.

Page 8 May 10

(b) If there are no correlated CMC messages go
directly to the task given in the “GO TO FIM
TASK” column.

If you have any doubts about how to use the FIM, refer to FAULT
ISOLATION MANUAL USAGE section.

Every effort has been made to ensure that the information
presented in the Quick-Reference Reset Guide is in accordance
with the Fault Isolation Manual. However, in the event of conflict
between them, the Fault Isolation Manual shall prevail.

NOTE: The Quick-Reference Reset Guide will be reissued on all
revisions.

MAU and SPDA RESET SAFETY PROCEDURES

MAU - MAINTENANCE SAFETY PROCEDURES

(1) EFFECTIVITY: PRE-MOD SB 170-24-0017 (ON ACFT
WITH SPDA BLOCK 6.1)

If the aircraft is energized with APU and you need to do
the reset of the MAU 1 and MAU 3, you must open the
following SSPC to avoid the RAT deployment:

•RAT DEPLOY-SPDA1 (CBMENU/CB BY SYS/ELEC)

(2) If the aircraft is energized with APU and you open the
circuit breaker MAU 3 PWR 1, the APU will shutdown.

NOTE: To avoid power interruption, you must energize
the aircraft with an AC external power supply.

(3) Before you reset MAU 1 or MAU 3 power supplies, make
sure that all switches on the HYDRAULIC CONTROL
PANEL are set at the OFF position.

(4) If you do the MAU reset procedure with the engines in
operation, engine related messages can show on the
EICAS. We recommend that you stop the engines before
the power-supply circuit-breaker cycling procedure.

(5) If it is necessary to open the MAU 1 and/or MAU 3 circuit
breakers, the message “SPOILER FAULT” “and “A-I
WING FAIL” will show on the EICAS.

(6) EFFECTIVITY: ON ACFT WITH ‘MAU2 PWR2 PRI’
CIRCUIT BREAKER ON DC ESS BUS 2

If it is necessary to open the MAU 2 PWR 2 PRI-RHCBP
(DC ESS BUS 2) circuit breaker, the message “RAT
FAIL” will show on the EICAS.

Page 10 May 10

(7) This procedure must be done to prevent the integrated
pitot/static/AOA and TAT system heating in any of these
situations:

- If you open one of these MAU 1 circuit breakers:

• MAU 1 PWR 2-LHCBP (DC ESS BUS 1)
• MAU 1 PWR 3-LHCBP (DC BUS 1)

- If you open one of these MAU 3 circuit breakers:

• MAU 3 PWR 1-RHCBP (DC ESS BUS 2)
• MAU 3 PWR 2-RHCBP (DC BUS 2)
• MAU 3 CUST I/O 2A-RHCBP (DC ESS BUS 2)
• MAU 3 CUST I/O 2B-RHCBP (DC BUS 2)

WARNING: THE INTEGRATED PITOT/STATIC/AOA
AND TAT HEATING SYSTEMS MUST BE OFF
DURING MAINTENANCE. THIS IS BECAUSE
SYSTEMS THAT INTERFACE WITH MAU 1, MAU 3
AND SPDA 2 CAN CAUSE THE INTEGRATED
PITOT/STATIC/AOAAND TAT SENSORS TO BECOME
HOT. THESE SENSORS OPERATE AT HIGH
TEMPERATURE. IF YOU TOUCH THEM, THEY WILL
CAUSE INJURIES TO YOU.

(a) Open this circuit breaker and put a circuit breaker ring
and tag (inoperative - do not operate) on it:

• PROBE 3 HEATER PWR-RHCBP (DC ESS BUS 3
NAV).

(b) On the MCDU, use the sequence in parentheses to
open these SSPCs:

• TAT 1 HEAT-SPDA1 (CBMENU/CB BY
SYS/ICE/RAIN).
• TAT 2 HEAT-SPDA1 (CBMENU/CB BY
SYS/ICE/RAIN).

Page 11 May 10

(c) Open these circuit breakers and put a circuit breaker
ring and tag (inoperative - do not operate) on each one of
them:

• ADS PROBE 1 HTR-LICC (DC BUS 1)
• ADS PROBE 2 HTR-LICC (DC BUS1)
• ADS PROBE 4 HTR-RICC (DC BUS 2)

(8) To restore the systems affected by the MAU safety
procedures to their initial condition, do as follows:

(a) Remove the circuit breaker ring and tag (inoperative -
do not operate) from this circuit breaker, and close it:

NAV)

(b) On the MCDU, use the sequence in parentheses to
close these SSPCs:
• TAT 1 HEAT-SPDA1 (CBMENU/CB BY SYS/ICE/RAIN)

(c) Remove the circuit breaker ring and tag (inoperative -
do not operate) from each of these circuit breakers, and
close them:


Page 12 May 10

SPDA - MAINTENANCE SAFETY PROCEDURES

(1) Before you reset SPDA 1 or SPDA 2 power supplies,
make sure that all switches on the HYDRAULIC
CONTROL PANEL are set at the OFF position.

(2) This procedure must be done to prevent the integrated
pitot/static/AOA and TAT system heating if you open one
of these SPDA 2 circuit breakers:

• SPDA2 PWR SPLY 1-RICC (DC BUS 2)
• SPDA2 PWR SPLY 3-EICC (DC ESS BUS 1)
• SPDA2 PWR SPLY 2-RICC (DC ESS BUS 2)
• SPDA2 PWR SPLY 4-LICC (DC GND SVC BUS)
• SPDA2 I-O MOD 11-RICC (DC ESS BUS 2)

WARNING: OBEY ALL THE SPDA SAFETY
PROCEDURES. IF YOU DO NOT OBEY THESE
PROCEDURES, INJURY TO PERSONS AND/OR
DAMAGE TO EQUIPMENT CAN OCCUR.

WARNING: THE INTEGRATED PITOT/STATIC/AOA
AND TAT HEATING SYSTEMS MUST BE OFF DURING
MAINTENANCE. THIS IS BECAUSE SYSTEMS THAT
INTERFACE WITH MAU 1, MAU 3 AND SPDA 2 CAN
CAUSE THE INTEGRATED PITOT/STATIC/AOA AND
AT SENSORS TO BECOME HOT. THESE SENSORS
OPERATE AT HIGH TEMPERATURE. IF YOU TOUCH
THEM, THEY WILL CAUSE INJURIES TO YOU.

(a) On the MCDU, use the sequence in parentheses to
open these SSPCs:

(b) Open these circuit breakers and put a circuit breaker
ring and tag (inoperative - do not operate) on each one of
them:

Page 13 May 10

NAV)

(3) To restore the systems affected by the SPDA safety
procedures, do as follows:

(a) On the MCDU, use the sequence in parentheses to
close these SSPCs:

(b) Remove the circuit breaker ring and tag (inoperative -
do not operate) from these circuit breakers, and close
them:
NAV)

General Information

The purpose of this section is to provide some standard procedures
and general information.

(1) The Quick-Reference Reset Guide must be used only
with the aircraft on the ground.

(2) To perform the procedures that follow, refer to AMM
TASK 45-45-00-970-805-A:
• MAU module reset test;
• Initiated BIT;
• PBIT;
• Clear Inhibit.

(3) To open and/or close a SSPC on the MCDU, refer to SDS
34-61-00.
