DTC C0625





Test 1-4





Test 5-13

Circuit Description
The Automatic Level Control (ALC) suspension position sensor is a potentiometer. The RIM determines the height of the rear of the vehicle based on the voltage from the suspension position sensor. The RIM raises or lowers the rear of the vehicle in order to keep the vehicle level.

Conditions for Running the DTC
The RIM is powered up and DTC B1327 is not set.

Conditions for Setting the DTC
^ The ALC position sensor signal voltage is less that 0.3 Volts or greater than 4.8 Volts.
^ The above conditions are present for greater than 10 seconds.

Action Taken When the DTC Sets
The automatic level control suspension will be inoperative. Conditions for Clearing the DTC
The RIM does not detect a voltage above or below the predetermined value during the diagnostic self test.

Diagnostic Aids
^ Inspect for the addition of any aftermarket components.
^ Inspect all wiring carefully for chaffing and proper routing.
Test Description
The numbers below refer to the step numbers on the diagnostic table.
4. Tests for the proper operation of the circuit in the high range. If the fuse in the jumper opens when you perform the test, the signal circuit is shorted to ground.
5. Tests for a short to voltage in the 5 volts reference circuit.
