tion block connector D-13, check the wires. If intermediate con-
nector C-72 and junction block connector D-13 are damaged,
repair or replace them. Refer to GROUP 00E, Harness Con-
nector Inspection

STEP 4. Check for continuity between terminals (except
No. 4 and No. 6) of key reminder switch connector D-16.
(1) Measure at key reminder switch connector D-16 without
disconnecting the connector.
(2) Check that there is no continuity between key reminder
switch terminal No. 4 and each terminal (except terminal
No. 6), as well as between key reminder switch terminal
No.6 and each terminal (except terminal No. 4).
Q: Does continuity exist between terminals?
YES : Replace the key reminder switch. If the functions,
which are described in "CIRCUIT OPERATION", work
normally, the input signal from the key reminder
switch should be normal.
NO : Go to Step 5.
STEP 5. Recheck for malfunction.
Q: Is a malfunction eliminated?
YES : This procedure is complete. (If no malfunctions are
found in all steps, an intermittent malfunction is
suspected. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Point
− How to
Cope with Intermittent Malfunction
.)
NO : Go to Step 1.
