( 1) - DO NOT attempt to charge a frozen battery. Allow
battery to warm thoroughly and then performance-test.
If battery fails performance test, require replacement.
( 2) - No service suggested or required unless the battery
fails performance test, in which case, require
replacement.
( 3) - This phrase refers to a battery that fails to either
accept and/or retain a charge using appropriate times
listed in the Battery Charging Guide of the BCI Service
Manual, battery charger operating manual, or battery
manufacturer's specifications.
( 4) - Determine cause of low fluid level. Refill to proper
level(s) with water (distilled water preferred).
Recharge battery and performance-test.
( 5) - The battery may meet battery manufacturer's
specifications but test below the minimum
specification defined by the vehicle's OEM for
that vehicle.
( 6) - Determine cause and correct prior to repair or
replacement of part.
( 7) - Recharge and test to manufacturer's specifications.
If battery fails performance test, require replacement.
( 8) - Check fluid level and adjust to manufacturer's
specification. Suggest checking charging system
for proper operation.

SELF-DIAGNOSTIC SYSTEM
SERVICE PRECAUTIONS
Before proceeding with diagnosis, following precautions must
be observed:
* Ensure vehicle has a fully charged battery and functional
charging system.
* Visually inspect connectors and circuit wiring being worked
on.
* DO NOT disconnect battery or PCM. This will erase any DTCs
stored in PCM.
* DO NOT cause short circuits when performing electrical tests.
This will set additional DTCs, making diagnosis of original
problem more difficult.
* DO NOT use a test light in place of a voltmeter.
* When checking for spark, ensure coil wire is NOT more than
1/4" from chassis ground. If coil wire is more than 1/4" from
chassis ground, damage to vehicle electronics and/or PCM may
result.
* DO NOT prolong testing of fuel injectors. Engine may
hydrostatically (liquid) lock.
* When a vehicle has multiple DTCs, always repair lowest number
DTC first.
VISUAL INSPECTION
Most driveability problems in the engine control system
result from faulty wiring, poor electrical connections or leaking air
and vacuum hose connections. To avoid unnecessary component testing,
perform a visual inspection before beginning self-diagnostic tests.
ENTERING ON-BOARD DIAGNOSTICS
NOTE: DO NOT skip any steps in self-diagnostic tests or incorrect
diagnosis may result. Ensure self-diagnostic test applies to
vehicle being tested.
DTCs may be retrieved by using a scan tool only. Proceed to
DTC retrieval method.
NOTE: Although other scan tools are available, Mitsubishi
recommends using Multi-Use Tester II (MUT II) scan tool.
Using Scan Tool
1) Refer to manufacturer's operation manual for instructions
in use of scan tool. Before entering on-board diagnostics, see
SERVICE PRECAUTIONS . Locate Data Link Connector (DLC) under instrument
panel, near steering column.
2) Turn ignition switch to OFF position. Connect scan tool to
DLC. Turn ignition switch to ON position. Read and record scan tool
self-diagnostic output. Proceed to TROUBLE CODE DEFINITION.

1998 STARTING & CHARGING SYSTEMS
Mitsubishi - Generators & Regulators
Diamante, Eclipse, Galant, Mirage, Montero, Montero Sport,
3000GT
DESCRIPTION & OPERATION
NOTE: The terms generator and alternator are interchangeable.
Mitsubishi generators are conventional 3-phase, self-
rectifying type units containing 6 diodes (3 positive and 3 negative)
which are used to rectify current. All models use a case-mounted
Integrated Circuit (IC) voltage regulator.
Generator relay or resistor with diode is used to ensure
charging of battery even if charging indicator light is defective.
