Nickel Metal Hydride Battery Replacement
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard
if mistreated. Do not recharge, disassemble of dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regula-
tions.

Circuit
INSPECTION PROCEDURE
If the CONSULT-II cannot diagnose the system properly, check the following items.
Symptom Check item
CONSULT-II cannot access
any system.
lCONSULT-II DLC power supply circuit (Terminal 7) and ground circuit (Terminal 8)
(For detailed circuit, refer to ªMIL & Data Link Connectors Wiring Diagramº in EC section.)
lCONSULT-II DDL cable
CONSULT-II cannot access
individual system. (Other sys-
tems can be accessed.)
lCONSULT-II program card (Check the appropriate CONSULT-II program card for the system.
Refer to ªChecking Equipmentº above.)
lPower supply and ground circuit for the control unite of the system
(For detailed circuit, refer to wiring diagram for each system.)
lOpen or short circuit between the system and CONSULT-II DLC
(For detailed circuit, refer to wiring diagram for each system.)
