COMPONENT TESTING
Before testing any of the components, perform
the following checks:
• Control failure can be the result of corrosion
on connectors. Therefore, disconnecting and
reconnecting wires will be necessary through-
out test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
• Unless stated otherwise, make all resis-
tance checks by disconnecting the compo-
nent connector at the electronic control.
