UNIFIED METER AND A/C AMPPFP:27760
System DescriptionBKS001SK

For the unified meter and A/C amp., the signal required for con-
trolling the combination meter are integrated in the A/C auto
amp.

Unified meter and A/C amp. controls each operation for A/C
auto amp. For information regarding A/C control, refer to AT C -
24, "AIR CONDITIONER CONTROL" .

Unified meter and A/C amp. inputs necessary information for
combination meter from each unit by CAN communication and
so on.

And unified meter and A/C amp. outputs these signals using
communication line (TX, RX) between unified meter and A/C
amp. and combination meter.

The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (with display unit) using CAN communication.

Other input signals are also sent to the ECM, TCM, BCM and display unit (with display unit) using CAN
communication.

The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor and data monitor).

DTC P1217 ENGINE OVER TEMPERATURE

CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-10, "
Changing Engine
Coolant" . Also, replace the engine oil. Refer to LU-9, "Changing Engine Oil" .
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-15, "
Anti-Freeze Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckBBS005GA
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-224,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-224,
"Diagnostic Procedure" .
3. Turn ignition switch ON.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II.
5. If the results are NG, go to EC-224, "
Diagnostic Procedure" .
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
