Ignition switch
Disconnect the ignition switch (A) from the wiring loom by opening its connector and use a
multimeter to check its internal connections as follows:
turn the key to OFF and connect a multimeter to contacts (1) and (4) to check electrical continuity.
The resistance reading should be near zero and, if present, the continuity sound signal should be
emitted.
Turn the key to ON and connect the multimeter to contacts (3) and (6) and then to (2) and (5) to
check for electrical continuity. The resistance reading should be near zero and, if present, the
continuity sound signal should be emitted.
Turn the key to PARK and connect the multimeter to contacts (1) and (4) and then to (3) and (5) to
check for electrical continuity. The resistance reading should be near zero and, if present, the
continuity sound signal should be emitted.
Turn the key to LOCK and connect the multimeter to contacts (1) and (4) to check for electrical
continuity. The resistance reading should be near zero and, if present, the continuity sound signal
should be emitted.
Disconnect battery.
Disconnect the ignition switch electrical connection.
Check the continuity of the ignition switch contacts following the enclosed electrical schematic and
using a multimeter.
