POWER MIRROR CONTROL SYSTEM (w/ Memory) - Mirror Heater does not Operate with Rear Defogger Switch
DESCRIPTION
- with Navigation System:
- When the mirror defogger switch, which is built into the multi-media module display assembly, is operated, the operation signals are transmitted to the A/C amplifier assembly through AVC-LAN and BEAN. When the A/C amplifier assembly receives the signals, it turns on the MIR HTR relay to operate the mirror defogger.
- without Navigation System:
- When the mirror defogger switch, which is built into the integration control & panel, is operated, the operation signals are transmitted to the A/C amplifier assembly through AVC-LAN and BEAN. When the A/C amplifier assembly receives the signals, it turns on the MIR HTR relay to operate the mirror defogger.

INSPECTION PROCEDURE
Select the DTC check on the intelligent tester to check for communication errors.
- Result:
| Not output DTC codes | A |
| Output DTC codes (Multiplex communication) | B |
| Output DTC codes (CAN communication) | C |
| 3.REPLACE MULTI-MEDIA MODULE DISPLAY |
Replace the multi-media module display.
| 4.CONFIRM MIRROR DEFOGGER OPERATION |
Turn the engine switch on (IG), press the defogger switch, and check that mirror heater operates.
| 11.CHECK WIRE HARNESS (MIR HTR RELAY) |
Disconnect the MIR HTR relay.
Measure the voltage according to the value(s) in the table below.
- Voltage:
| Tester Connection | Condition | Specified Condition |
| 1 - Body ground | Engine switch on (IG) | 10 to 14 V |
| | REPAIR OR REPLACE LH-IG FUSE OR HARNESS AND CONNECTOR |
|
|
| 12.CHECK WIRE HARNESS (MIR HTR RELAY - A/C AMPLIFIER ASSEMBLY) |
Disconnect the MIR HTR relay and A/C amplifier assembly connector.
Measure the resistance according to the value(s) in the table below.
- Resistance:
| Tester Connection | Condition | Specified Condition |
| 2 - J58-2 (MHTR) | Always | Below 1 Ω |
| 2 - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| OK | |
| |
| REPLACE A/C AMPLIFIER ASSEMBLY |
|
| 14.CHECK WIRE HARNESS (MIR HTR RELAY - BATTERY POSITIVE AND BODY GROUND) |
Disconnect the MIR HTR relay.
Measure the voltage according to the value(s) in the table below.
- Voltage:
| Tester Connection | Condition | Specified Condition |
| 5 - Body ground | Engine switch on (IG) | 10 to 14 V |
| | REPAIR OR REPLACE MIR HTR FUSE OR HARNESS |
|
|
| 15.CHECK WIRE HARNESS (MIR HTR RELAY - OUTER MIRROR ASSEMBLY) |
Disconnect the MIR HTR relay and outer rear view mirror assembly connectors.
Measure the resistance according to the value(s) in the table below.
(*): Outer rear view mirror assembly RH
- Resistance:
- Outer rear view mirror assembly LH:
| Tester Connection | Condition | Specified Condition |
| 3 - M15-3 (HTR+) | Always | Below 1 Ω |
| 3 - Body ground | Always | 10 kΩ or higher |
| M15-9 (HTR-) - Body ground | Always | Below 1 Ω |
- Outer rear view mirror assembly RH:
| Tester Connection | Condition | Specified Condition |
| 3 - L14-3 (HTR+) | Always | Below 1 Ω |
| 3 - Body ground | Always | 10 kΩ or higher |
| L14-9 (HTR-) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| OK | |
| |
| REPLACE OUTER REAR VIEW MIRROR ASSEMBLY |
