2. Turn the ignition switch to the ON position. The
multimeter should read battery voltage. If battery
voltage is not indicated, check the 30-amp fuse in the
PDM or the 10-amp ignition fuse, wiring harness, or
the ignition switch.
3. Remove the red tester lead and connect to the pin B.
The multimeter should read approximately 2.5 DC
volts (700) or 0.5 DC volts (500). If the specified
voltage is not indicated, check wire connections at
the ECM or substitute another ECM to verify the
test.

2. Install the needle adapters to the multimeter leads;
then select DC Voltage on the multimeter.
3. Connect the red tester lead to the blue/brown wire
(B) and the black tester lead to the black/yellow wire
(A); then turn the ignition switch ON and observe the
meter. The meter should read 0.8-3.0 DC volts (700)
or 0.3-1.5 DC volts (500).

4. Tilt the sensor 60° or more to the left and right
observing the meter. The meter should read 4.0-8.0
DC volts (700) or 3.0-7.0 DC volts (500) after
approximately one second in the tilted position. If
the meter readings are not as specified, the tilt sensor
is defective.
