MONITOR DESCRIPTION
The battery supplies electricity to the ECM even when the ignition switch is off. This power allows the ECM to store data such as DTC history, freeze frame data and fuel trim values. If the battery voltage falls below a minimum level, these memories are cleared and the ECM determines that there is a malfunction in the power supply circuit. When the engine is next started, the ECM illuminates the MIL and sets the DTC.
HINT:
If DTC P0560 is set, the ECM does not store other DTCs.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
1 CHECK FUSE (EFI NO. 1 FUSE)
(a) Remove the EFI No. 1 fuse from the engine room junction block.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance: Below 1 Ω
(c) Reinstall the EFI No. 1 fuse.
2 INSPECT ECM (BATT VOLTAGE)
(a) Measure the voltage according to the value(s) in the table below.
Standard voltage
REPLACE ECM (See page ES-498)
3 CHECK HARNESS AND CONNECTOR (ECM - EFI NO. 1 FUSE)
(a) Check the harness and the connector between the EFI No. 1 fuse and ECM.
(1) Remove the EFI No. 1 fuse from the engine room junction block.
(2) Disconnect the E4 ECM connector.
(3) Measure the resistance according to the value(s) in the table below.
Standard resistance :
(4) Reconnect the ECM connector.
(5) Reinstall the EFI No. 1 fuse.
4 CHECK HARNESS AND CONNECTOR (EFI NO. 1 FUSE - BATTERY)
(a) Check the harness and the connector between the EFI No. 1 fuse and battery.
(1) Remove the EFI No. 1 fuse from the engine room junction block.
(2) Disconnect the negative battery cable.
(3) Measure the resistance according to the value(s) in the table below.
Standard resistance:
(4) Reconnect the negative battery cable.
(5) Reinstall the EFI No. 1 fuse
5 INSPECT BATTERY
(a) Check that the battery is not depleted.
CHECK AND REPLACE ENGINE ROOM RELAY BLOCK

Calibrating the compass
The direction display deviates from the true direction determined by
the earth’s magnetic field. The amount of deviation varies according to
the geographic position of the vehicle.
If you cross over a map boundary shown in illustration, the compass will
deviate.
To obtain higher preci ...
