Rearview Monitor Mirror Input Test/Replacement
NOTE:
The normal operating temperature range of rearview monitor mirror is -22 °F to 176 °F(-30 °C to 80 °C). Allow the inside temperature of the vehicle to stabilize within the normal operating range before testing.
- Turn the ignition switch to ON (II).
- Check the auto dimming inside mirror indicator. If the indicator flashes two times, and then turns on, there is a malfunction in the mirror. Replace it.
- Remove the roof console. (seeHEADLINER REMOVAL/INSTALLATION )
- Disconnect the 12P connector (A) from the roof wire harness (B).
- Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 6.
- Reconnect the 12P connector to the roof harness at the rearview mirror. Remove the tailgate lower trim panel (see TRIM REMOVAL/INSTALLATION - TAILGATE AREA ) to access the rearview camera 6P connector.
- With the connector still disconnected, make these input tests at the connector.NOTE: Make sure the connector is connected while testing terminals 12, 5 and 6. Make sure the connector is disconnected while testing terminals 3,8,2,1, and 7.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK. Substitute and connect a known-good rearview camera and check the monitor image in reverse. If the symptom is gone, the rearview camera is faulty; replace it. If the symptom is still present, the rearview mirror is faulty; replace it.
WIRE CAVITY CHARTCavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 12 BLK Under all conditions Measure the voltage between the No. 12 terminal and body ground:
There should be less than 0.5 V.- An open in the wire
- Poor ground (G601)
5 BLK/YEL Ignition switch ON (II) Measure the voltage between No. 5 terminal and body ground:
There should be battery voltage.- An open in the wire
- Blown No. 30 (10 A) fuse in the driver's under-dash fuse/relay box
- Faulty passenger's under-dash fuse/relay box
6 GRN Ignition switch ON (II) and the transmission shift lever in reverse Measure the voltage between to ground:
There should be battery voltage.- An open in the wire
- Faulty driver's under-dash fuse/relay box (MICU)
- Blown No. 21 (7.5 A) fuse in the driver's under - dash fuse/relay box
- Faulty transmission range switch
- Poor ground (G101)
