The sequence will repeat as long as there is a fault present. During a
multiple-fault condition, the error codes will flash in order of fault
priority. After the first fault is corrected, the error code for the second
fault will flash and so on, until all faults are corrected.
When an error code is displayed via the red indicator light, record the
error code. Before in-depth troubleshooting, carry out the following
procedure:
7.11.1 Turn the ignition switch OFF and then back ON again. Check the
function of the steering system on all three circuits: right, side, and left.
• If the red indicator light is no longer flashing and the system is
functioning, no further action is required.
• If the red indicator light is still flashing, turn the ignition switch
OFF and continue.
7.11.2 Use a digital multimeter to check the battery voltage. It must be over
11VDC for proper operation.
• If the battery voltage is under 11VDC, charge or replace it.
• If the battery voltage is 11VDC or more, continue.
7.11.3 Check the 70A maxi-fuse for the steering control system actuators. It
is located under the seat pedestal above the relays and ignition
module cover.
• If the 70A maxi-fuse is blown, replace it.
• If the 70A maxi-fuse is not blown, continue with in-depth trouble-
shooting.
