S2000 L4-2.2L (2004)
Heated Element: Testing and Inspection
Function Test
1. Remove the driver's door panel.
2. Disconnect the 10P connector (A) from the power mirror switch (B),and inspect the terminals. If the terminals are OK, go to step 3.
3. Choose the appropriate test based on the symptom:
-
Both mirrors don't work, go to step 4.
-
Left mirror doesn't work, go to step 6.
-
Right mirror doesn't work, go to step 7.
Both mirrors
4. Reconnect the 10P connector, and check for voltage between the No.9 terminal and body ground with the ignition switch ON (II). There should be
battery voltage. Move the mirror selector switch to the left or right and hold down the mirror switch in any direction.
-
If there is no battery voltage, check for:
-
blown No.19 (7.5 A) fuse in the under-dash fuse/relay box.
-
an open in the YEL/BLK wire.
-
If there is battery voltage, go to step 5.
5. Check for continuity between the No.10 terminal and body ground.
Move the mirror selector switch to the left or right and hold down the mirror switch in any direction. There should bo less than 1 V.
-
If there is no more than 1 V, check for:
-
an open in the BLK wire.
-
poor ground (G501).
-
If there is less than 1 V, check both mirrors individually cis described in the next column.
Left mirror
6. Connect the No.9 terminal to the No.7 terminal, and the No.5 (or No.4) terminal to body ground with jumper wires. The left mirror should tilt
down (or swing left) with the ignition switch ON (II).
-
If the mirror does not tilt down (or does not swing left), check for an open in the GRN/WHT (or RED) wire between the left mirror and the
10P connector. If the wire is OK, check the left mirror actuator.
-
If the mirror neither tilts down nor swings left, repair the RED/YEL wire.
-
If the mirror works properly, check the mirror switch.
Right mirror
7. Connect the No.9 terminal to the No.6 terminal, and the No.5 (or No.3) terminal to body ground with jumper wires. The right mirror should tilt
down (or swing left) with the ignition switch ON (II).
-
If the mirror does not tilt down (or does not swing left), check for an open in the GRN/WHT (or BLU/WHT) wire between the right mirror and
the 10P connector. If the wire is OK, check the right mirror actuator.
-
If the mirror neither tilts down nor swings left, repair the RED/BLU wire.
-
If the mirror works properly, check the mirror switch.
