Troubleshooting Section

Intermittent electrical problems often disappear

by disconnecting and reconnecting connectors.

It is very important to check for diagnostic codes

immediately before disconnecting a connector. Also

check for diagnostic codes after reconnecting any

connectors. If the status of a diagnostic code is

changed due to disconnecting and reconnecting a

connector, there are several possible reasons. The

likely problems are loose or improperly crimped

terminals, moisture, corrosion, or connectors not

mated securely.

ALWAYS crimp the terminals on the wires with the

1U-5804 Crimp Tool. Do not solder the terminals.
