DIAGNOSTIC
XR25
If a bar does no appear in the first section, check
all connections for good contact. If a bar appears
in one of the other three sections, a fault is
indicated. On "Type 1" and "Type 2", this test
monitors solenoid valve and road speed sensor
circuits. On "Type 2" only, continuity through the
potentiometer circuit is also checked.

Reading the display
This test appears in the lower window of the
XR25. For this, the engine should be stopped and
the ignition switched on. This checks the
multi-purpose switch and the kickdown circuit.
With the shift selector in the first gear hold
position, the bars in section 4 and 5 of the display
should appear. Move the selector to the second
gear hold position and only 4 should appear.
When the selector lever is moved to drive,
neutral, reverse or park, no bars should appear.
Check the kickdown switch by pressing the
accelerator pedal to the floor. A bar must appear
in section 6; if not, the switch is defective and
must be replaced. Be certain the floor mat does
not interfere with accelerator travel.
