RVM warning indicator light does not illuminate under illumination conditions |
|---|---|
|
DESCRIPTION
|
• RVM warning indicator light flashes/does not illuminate despite satisfying the conditions to illuminate RVM warning indicator light (vehicle speed above 60 km/h {37 mph}, turn signals off, and vehicle in detection area).
|
|
POSSIBLE CAUSES
|
• Rear vehicle monitoring control modules false-detect that a vehicle is outside detection area when it is actually inside of it, or cannot determine that no vehicle is entering blind-spot area.
• Rear vehicle monitoring control modules do not detect vehicle speed correctly (false-detects vehicle speed as being within 55 km/h {34 mph} constantly)
• Rear vehicle monitoring control modules false-detect that vehicle is traveling on gentle curve (small curvature).
• Rear vehicle monitoring control modules do not detect selector lever position correctly (selector lever in reverse (MTX)/R position (ATX)).
• RVM warning indicator light illumination related malfunction
• Rear vehicle monitoring control modules false-detect that turn signals are on.

Diagnostic Procedure
|
Step |
Inspection |
Action |
|
|---|---|---|---|
|
1
|
VERIFY DTCs
• Retrieve DTCs from the rear vehicle monitoring system, PCM, TCM (ATX), BCM (MTX), DSC, and instrument cluster using the M-MDS.
(See DTC INSPECTION [BCM].)
• Are any DTCs displayed?
|
Yes
|
Go to the applicable DTC inspection.
(See DTC TABLE [ZY, Z6].)
(See DTC TABLE [LF, L5].)
(See DTC TABLE [L3 Turbo].)
(See DTC TABLE [MZR-CD 2.2].)
(See DTC TABLE [BCM].)
|
|
No
|
Go to the next step.

|
DETERMINE IF MALFUNCTION CAUSE IS RVM WARNING LIGHT (AMBER) OR RVM WARNING INDICATOR LIGHT ILLUMINATION CIRCUIT
• Switch the ignition to ON.
• Turn on and off the RVM warning indicator light using the following rear vehicle monitoring system active commands by the M-MDS:
• Does the RVM warning indicator light turn on and off according to active command?
|
Yes
|
Go to Step 4.
|
|
No
|
Go to the next step.
|
||
|
3
|
DETERMINE IF MALFUNCTION CAUSE IS REAR VEHICLE MONITORING CONTROL MODULES OR RVM WARNING INDICATOR LIGHTS
• Inspect the following:
RVM warning indicator light (RH) related:
RVM warning indicator light (LH) related:
• Is any malfunction verified?
|
Yes
|
Repair or replace the malfunctioning part.
|
|
No
|
Replace the rear vehicle monitoring control module (LH).
|
||
|
4
|
DETERMINE IF MALFUNCTION CAUSE IS INPUT SIGNAL OR REAR VEHICLE MONITORING CONTROL MODULES RELATED
• Monitor the following rear vehicle monitoring system and BCM (MTX)/TCM (ATX) PIDs using the M-MDS:
Rear vehicle monitoring system PIDs:
BCM PID (MTX):
TCM PID (ATX):
• Are the monitoring values normal?
|
Yes
|
Go to Step 10.
|
|
No
|
• If the VSPD monitoring value is not normal, go to the next step.
• If the YAW_RATE monitoring value is not normal:
• If the R_GEAR_SW monitoring value is not normal, go to Step 8.
• If the TR monitoring value is not normal, go to Step 9.
|
||
|
5
|
INSPECT VEHICLE SPEED SIGNAL
• Monitor the PID VSS for the PCM using the M-MDS.
• Are the monitoring values normal?
|
Yes
|
Replace the rear vehicle monitoring control module (RH).
|
|
No
|
Inspect the ABS wheel speed sensor related parts.
|
||
|
6
|
INSPECT YAW RATE SENSOR
• Inspect the yaw rate sensor (combined sensor).
(See COMBINED SENSOR INSPECTION.)
• Is the yaw rate sensor normal?
|
Yes
|
Replace the rear vehicle monitoring control module (RH).
|
|
No
|
Replace the combined sensor.
|
||
|
7
|
INSPECT YAW RATE SENSOR
• Inspect the DTC for the SAS control module ON-BOARD DIAGNOSTIC SYSTEM.
(See DTC INSPECTION [TYPE B].)
• Have DTCs C1280 been recorded in memory?
|
Yes
|
Inspect the DTC C1280 for the SAS control module.
|
|
No
|
Replace the rear vehicle monitoring control module (RH).
|
||
|
8
|
INSPECT BACK-UP LIGHT SWITCH
• Inspect the back-up light switch.
• Is the back-up light switch normal?
|
Yes
|
Inspect the back-up light switch related wiring harness.
If normal, replace the rear vehicle monitoring control module (RH).
|
|
No
|
Replace the back-up light switch.
|
||
|
9
|
INSPECT TR SWITCH
• Inspect the TR switch.
• Is the TR switch normal?
|
Yes
|
Inspect the TR switch related wiring harness.
If normal, replace the rear vehicle monitoring control module (RH).
|
|
No
|
Replace the TR switch.
|
||
|
10
|
VERIFY REAR BUMPER CONDITION
• Inspect the rear bumper at the rear vehicle monitoring control modules installation areas for the following:
• Is the rear bumper condition normal?
|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace the malfunctioning part, or replace the rear bumper.
|
||
|
11
|
VERIFY INSTALLATION CONDITION OF REAR VEHICLE MONITORING CONTROL MODULES
• Remove the rear bumper.
• Inspect the installation condition of the rear vehicle monitoring control modules for the following:
• Is the rear vehicle monitoring control modules installation condition normal?
|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace the malfunctioning part.
|
||
|
12
|
VERIFY IF MALFUNCTION CAUSE IS AFTER-MARKET ELECTRONIC DEVICE INSTALLATION
• Disconnect the non-genuine, after-market electronic device connectors.
• Verify if the malfunction symptom recurs as stated by the customer.
• Does the malfunction recur?
|
Yes
|
Go to the next step.
|
|
No
|
Explain to the customer that the malfunction occurred due to the after-market electronic device installation.
|
||
|
13
|
INSPECT REAR VEHICLE MONITORING CONTROL MODULES
• Inspect the malfunctioning rear vehicle monitoring control module.
• Is the rear vehicle monitoring control module normal?
|
Yes
|
Temporary malfunction with the radar echo-back.
If the same symptom recurs repeatedly, replace the rear vehicle monitoring control module.
|
|
No
|
Replace the rear vehicle monitoring control module.
