Nissan Pick-ups and Pathfinder 1989-1995
Do not operate the fuel pump when the fuel lines are empty.
Do not reuse fuel hose clamps.
Do not disengage the ECCS harness connectors before the battery ground cable has been disconnected.
Make sure all ECCS connectors are fastened securely. A poor connection can cause an extremely high voltage surge and result in damage to integrated circuits.
Keep the ECCS harness at least 6 in. (15 cm) away from adjacent harnesses to prevent an ECCS system malfunction due to external electronic "noise.''
Keep all parts and harnesses dry during service.
Before attempting to remove any parts, turn the ignition switch
and disconnect the battery ground cable.
Always use a 12 volt battery as a power source.
Do not attempt to disconnect the battery cables with the engine running.
Do not depress the accelerator pedal when starting.
Do not rev up the engine immediately after starting or just prior to shutdown.
Do not attempt to disassemble the ECCS control unit under any circumstances.
If a battery cable is disconnected, the memory will return to the ROM (programmed) values. Engine operation may vary slightly, but this is not an indication of a problem. Do not replace parts because of a slight variation.
If installing a 2-way or CB radio, keep the antenna as far away as possible from the electronic control unit. Keep the antenna feeder line at least 12 in. (30 cm) away from the ECCS harness and to not let the 2 run parallel for a long distance. Be sure to ground the radio to the vehicle body.
