0A-16 GENERAL INFORMATION
PRECAUTION FOR INSTALLING MOBILE
COMMUNICATION EQUIPMENT
When installing mobile communication equipment such as CB (Citi-
zens-Band)-radio or cellular-telephone, be sure to observe the fol-
lowing precautions.
Failure to follow cautions may adversely affect electronic control
system.

Keep the antenna as far away as possible from the vehicle’s elec-
tronic control unit.

Keep the antenna feeder more than 20 cm (7.9 in.) away from
electronic control unit and its wire harnesses.

Do not run the antenna feeder parallel with other wire harnesses.

Confirm that the antenna and feeder are correctly adjusted.

“LAMP”
DTC P1510 ECM (PCM) BACK-UP POWER SUPPLY MALFUNCTION
CIRCUIT DESCRIPTION
Battery voltage is supplied so that diagnostic trouble code memory, values for engine control learned by ECM
(PCM), etc. are kept in ECM (PCM) even when the ignition switch is turned OFF.
DTC DETECTING CONDITION
POSSIBLE CAUSE

Low voltage at terminal C02-7 after starting engine.
“W” circuit open

ECM (PCM) malfunction
DTC CONFIRMATION PROCEDURE
1) Clear DTC, start engine and run it at idle for 1 min.
2) Select “DTC” mode on scan tool and check DTC.
INSPECTION
STEPACTIONYESNO
1Check for voltage at terminal C02-7 of ECM
(PCM)connector connected, under each
condition, ignition switch OFF and engine
running.
Is it 10 – 14 V at each condition?Poor C02-7 connection
or intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection”
in Section 0A.
If wire and connections
are OK, substitute a
known- good ECM
(PCM) and recheck.“W” circuit open.

TYPE 1 TYPE 2
BODY ELECTRICAL SYSTEM 8-3
KEYLESS ENTRY SYSTEM (IF EQUIPPED)
The keyless entry system uses radio wave. When the button on the transmitter is pressed, a signal is transmitted
in the form of radio wave to the receiver. Then the signal causes the door lock controller to lock and unlock the door.
The door locks can not operated with the transmitter when either of the following conditions applies.

For 2 seconds after the ignition switch is turned from ON to OFF position.

The ignition switch is at ON or START position.

Any door is open.

NOTE:

The operation distance of this system varies depending on the position where the transmitter is oper-
ated, at the front side, the rear side or the lateral side. The distance can be affected by radio noises from
a TV station, a power plant, a broadcasting station and so forth.

ECT SENSOR
INSPECTION
1) Warm up ECT sensor (1) observing resistance between sensor
terminal (2) and sensor unit (1). Resistance should be de-
creased with increase of its temperature.
2) Check resistance between sensor terminal (2) and sensor unit
(1). If check result is not as specified below, replace sensor.
