1. Remove the power window master switch (A).
2. Disconnect the 13P connector (B) from the powermirror switch.
3. Choose the appropriate test based on the symptom:
 Both mirrors don’t work, go to step 4.
 Leftmirrordoesn’twork,gotostep6.
 Right mirror doesn’t work, go to step 7.
4. Measure the voltage between terminal No. 2 and body ground with the ignition switch turned to ON
(II).
There should be battery voltage.
 If there is no voltage, check for: – Blown No. 36 (10 A) fuse in the under-dash fuse/relay box.
– AnopenintheBRNwire.
 If there is battery voltage, go to step 5.
5. Check for continuity between terminal No. 6 and body ground. There should be continuity.
 If there is no continuity, check for: – AnopenintheBLKwire.
– Poor ground (G 503).
 If there is continuity, check both mirrors individually as described in the next steps. 6. Connect terminals No. 2 and No. 10, and terminals
No. 5 (or No. 12) and No. 6 with jumper wires.
The left mirror should tilt down (or swing left) with
the ignition switch to ON (II).
 If the left mirror does not tilt down (or does not swing left), check for an open in the PUR (or PNK)
wire between the left mirror and the 13P
connector.
If the wire is OK, check the left mirror actuator.
 If the mirror neither tilts down nor swings left, repair the GRN wire.
 If the mirror works properly, check the mirror switch.
7. Connect terminals No. 2 and No. 11, and terminals No. 5 (or No. 13) and No. 6 with jumper wires. The
right mirror should tilt down (or swing left) with the
ignition switch to ON (II).
 If the mirror does not tilt down (or does not swing left), check for an open in the PUR (or BLU) wire
between the right mirror and the 13P connector.
If the wire is OK, check the right mirror actuator.
 If the mirror neither tilts down nor swings left, repair the WHT wire.
 If the mirror works properly, check the mirror switch.
8. Connect the power mirror defogger relay terminals No. 1 and No. 2 in the under-hood fuse/relay box
with a jumper wire, and measure the voltage
between mirror connectors terminal No. 1 and
body ground. There should be battery voltage and
both mirrors should warm up with the ignition
switch to ON (II). If there is no voltage or neither warms up, check for:
– AnopenintheORNwire.
– Blown No. 36 (10 A) fuse in the under-dash fuse/relay box.
 If only one fails to warm up, check: – Its defogger.
– Poor ground (G 503).
 If both warm up, check the defogger switch.

NOTE:
 Be careful not to scratch or damage the defogger wires with the tester probe.
 Before testing, check the No. 8 (30 A) fuse in the under-hood fuse/relay box and the No. 36 (10 A) fuse
in the under-dash fuse/relay box.
1. Measure the voltage between the positive terminal (A) and body ground with the ignition switch turned
to ON (II) and the defogger switch ON.
There should be battery voltage.
 If there is no voltage, check for: – Faulty rear window defogger relay.
– Faulty climate control unit.
– An open in the RED wire to the positive terminal.
 If there is voltage, go to step 2. 2. Disconnect the negative terminal (B) from the rear
window defogger.
3. Check for continuity between the negative terminal and body ground.
If there is no continuity, check for an open in the
wire or poor ground (G 801). If there is continuity,
go to step 4.
4. Reconnect the negative terminal to the rear window defogger.
5. Turn the ignition switch to ON (II) and the rear window defogger switch ON.
6. Touch the voltmeter positive probe to each point on each defogger wire, and the negative probe to
the negative terminal.
 If the voltage is as specified, the defogger wire up to that point is OK.
 If the voltage is not as specified, repair the defogger wire.
– If it is more than specified at one of the points, there is a break in the negative half of the wire.
– If it is less than specified at one of the points, there is a break in the positive half of the wire.

Symptom Troubleshooting by the Immobilizer Indicator Lighting Pattern
General Check before Troubleshooting
Normal operation
Immobilizer code is not identified
Immobilizer indicator does not come on
Immobilizer indicator does not go off
22-321
Symptom Troubleshooting Information
Immobilizer system condition can be checked by the immobilizer indicator lighting pattern.
If the immobilizer code is identified, the immobilizer indicator comes on for 2 seconds, then goes off after turning the
ignition switch to ON (II).
The immobilizer indicator does not come on when the ignition switch is turned to LOCK (0).
If the immobilizer code is not identified, the immobilizer indicator comes on for 2 seconds, then blinks after turning the
ignition switch to ON (II).
The immobilizer indicator blinks ten times, then goes off when the ignition switch is turned to LOCK (0).
If the immobilizer indicator does not come on after turning the ignition switch to ON (II), there may be an open or short
in the F-CAN lines between the ECM/PCM and the gauge control module (tach). Watch the malfunction indicator lamp
(MIL). If the MIL stays on, go to the PGM-FI system troubleshooting (see page 11- 203).
If the immobilizer indicator does not go off after turning the ignition switch to ON (II), do the gauge control m odule
(tach) self-diagnostic function (see page 22- 241). If the indicator drive circuit is OK, verify the SYSTEM CHECK with the
HDS.
Before troubleshooting the immobilizer system, check the following general points and solve any if applicable.
 Battery is low; charge the battery fully, then troubleshoot the immob ilizer system.
 Ignition key is not a genuine Honda part; use the Acura-approved key blank, register the key, then troubleshoot the immobilizer system.
 Key ring, or keys, or a key case is used; remove the key from it, and troubleshoot the immob ilizer system with a key
only.
 Aftermarket electrical part is attached; remove it, then troubleshoot the immob ilizer system.

NOTE: If the HDS does not communicate with the vehicle, troubleshoot the DLC circuit (see page 11-
204).
1. Do the PGM-FI system DTCs check. If there are any DTCs, troubleshoot the indicated DTC.
2. Do the Body Electrical DTCs check. If there are any DTC, troubleshoot the indicated DTC.
3. Do the system check using the HDS. If there is a system check number, do the troubleshooting for the item indicated (see page 22-326).
4. Check the status log using the HDS. Troubleshoot the line with the highest counts (see page 22-328). If all the lines are ‘‘0’’ zero, the problem may not be caused by the immobilizer system, check for ignition or fuel problems.
NOTE: Once repaired, clear the status log by removing the back up power fuse, or disconnecting the battery.
If a malfunction occurs in the immobilizer circuit for the VBU, IG1 and GND (LG) lines, identify the lines to check with
this table.
