senger Memory Mirror system’s circuits and components. Select only that which applies to the system you
are diagnosing.
Diagnostic Test
1.
TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTCs.
Operate the Mirror Switch in all directions several times.
Cycle the ignition from on to off 3 times.
Turn the ignition on.
With the scan tool, read DTCs.
Does the scan tool display: B1D24 or B1D30 MIRROR HORIZONTAL MOTOR CONTROL CIRCUIT HIGH?
Yes
>> Go To 2
No
>> The conditions that caused this code to set are not present at this time. Using the wiring diagram/sche-
matic as a guide, inspect the wiring and connectors.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES - STANDARD PROCEDURE).
