2000 TOYOTA CAMRY wiring diagram

Remove glove compartment.
(See page EG1±234)
Measure voltage between terminal BATT of en±
gine control module connector and body ground.
Voltage: 9 ±14 V
Check voltage between terminal BATT of engine control module
connector and body ground.
Are the diagnostic trouble codes still in the memory when the
ignition switch is turned OFF?
Check and repair harness or connector
between engine control module and EN
fuse, EFI fuse and battery. Remove EFI fuse from J/B No.2.
Check continuity of EFI fuse.
Continuity
Check for short in all the harness and
components connected to EFI fuse
(See attached wiring diagram).
Proceed to next circuit inspection shown on
matrix chart (See page EG1±327).Check and replace engine control module.
INSPECTION PROCEDURE
Check EFI fuse.

CIRCUIT DESCRIPTION
This circuit cuts air conditioning operation during vehicle acceleration in order to increase accelera±
tion performance. During acceleration with the vehicle speed at 16 mph (25 km/h) or less, engine
speed at 1,200 rpm or less and throttle valve opening angle at 60or more, the A/C magnet switch
is turned OFF for several seconds.
Air Conditioning Cut Control Circuit
Check for open and short in harness and
connector between ECM and A/C amplifier.

Repair or replace harness or connector.
DIAGNOSTIC CHART
Check and replace A/C amplifier.Check voltage terminal ACT.
Check and replace ECM.

DIAGNOSTIC CHART
HINT: If terminals TE1 and TE2 are connected with terminal E1, diagnostic trouble code is not
output or test mode is not activated.
Even though terminal TE1 is not connected with terminal E1, the malfunction indicator lamp
blinks.
For the above phenomenon, the likely cause is an open or short in the wire harness, or
malfunction inside the ECM.
CIRCUIT DESCRIPTION
Terminals TE1 and TE2 are located in the data link connector 1 and 2.
The data link connector 1 located in the engine compartment and the data link connector 2 located
in the cabin. When these terminals are connected with the E1 terminal, diagnostic trouble codes in
normal mode or test mode can be read from the malfunction indicator lamp on the combination meter.
Check for open and short in harness and
connector between data link connector 1, 2
and ECM.Check continuity between terminal E1 and body
ground.
TE1 TE2 Terminal Circuit
Repair or replace harness or connector.Repair or replace harness or connector. Check voltage of terminals TE1, TE2.
