Code 66 - Adjuster Assembly Control: Notes

Power and ground are supplied to adjuster assembly which controls engine torque during ASR operation.

During ASR operation, if EBCM delivers current greater than 16 amps to adjuster assembly for longer than 3 seconds without adjuster assembly reaching desired position, Code 66 will be set.

1. Checks for Code 65 conditions, which can affect Code 66.
2. Checks for mechanical binding of adjuster assembly, attached cables and related components. Binding would cause excessive load on adjuster assembly.
3. Because Code 66 will only set during ASR operation, vehicle is raised to force ASR operation by allowing rear wheels to spin while front wheels remain still.
