Code 65 - Adjuster Assembly (1 Of 2): Notes
Power and ground are supplied to adjuster assembly which controls engine torque during ASR operation.
Code 65 will set if circuits No. 1685 or No. 1686 are both open or if they are shorted to ground, shorted to battery voltage or shorted to each other. SERVICE ASR indicator light will come on and ASR system will be disabled for the remainder of the ignition cycle.
NOTE:
Test numbers refer to circled numbers on diagnostic chart.
- Measures resistance in adjuster assembly motor windings. Rotating and releasing adjuster before measuring resistance, allows motor to reach home position.
- Checks for open in circuits No. 1685B and No. 1685C.
- Checks for open in circuits No. 1686B and No. 1686C.
- Checks for short between circuits No. 1685A and No. 1686A.
- Checks for short to battery voltage in circuits No. 1685A, No. 1685B and No. 1685C.
- Repeats rotate and release procedure from step 1). Adjuster assembly resistance should be .5-10 ohms at least once after this procedure.
- Checks for code reset by moving throttle valve position to enable one of the EBCM's adjuster assembly monitoring systems to check for a code reset.
- Checks for wiring or connection problem which could cause intermittent condition.
