Trouble Diagnosis Summary of Multi-Remote Control System
ALL FUNCTION OF MULTI-REMOTE CONTROL SYSTEM DO NOT OPERATESystem Description
Remote controller signal is inputted to smart entrance control unit. (The antenna of the system is combined with smart entrance control unit.)
The multi-remote control system controls operation of the power door lock, interior lamp, panic alarm, trunk lid opener and hazard and horn reminder.
Smart entrance control unit receives a LOCK signal from remote controller. Smart entrance control unit locks all doors with input of LOCK signal from remote controller. When an UNLOCK signal is sent from remote controller once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from remote controller again within five seconds, all other doors will be unlocked.
When smart entrance control unit receives LOCK or UNLOCK signal from remote controller with all doors closed, hazard warning lamp flashes and horn sounds as a reminder. (Horn can be activated or deactivated.) When interior lamp switch is set to DOOR position, all doors are closed and driver's door is locked; multi-remote control system turns on interior lamp for 30 seconds with input of UNLOCK signal from remote controller.
When ignition key is not inserted into key cylinder, multi-remote control system turns on and off horn and headlamp intermittently with input of PANIC ALARM signal from remote controller.
The alarm automatically turns off after 25 seconds or when smart entrance control unit receives any signal from remote controller.
When a TRUNK OPEN signal is sent from remote controller, trunk lid opener actuator opens trunk lid.
Possible Cause
- Remote controller battery
- Remote controller
- Circuit open or short
Diagnostic Repair Procedure (for confirmed incidents)
1. Check remote controller battery: Proper installation and voltage spec = 3 Vor more.
