Entry Lock Switch Circuit
Circuit diagnosis
DESCRIPTION
The entry lock switches (trigger switch) are built into the outside handles of the LH/RH door. The certification ECU detects the conditions of the each lock switch.WIRING DIAGRAM
INSPECTION PROCEDURE
| 1. INSPECT ENTRY LOCK SWITCH |
Remove the outside handle.
Disconnect the connectors.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester Connection (Symbols)
Condition
Specified Condition
o1-1 (TRG-) - o1-3 (TRG+)
Lock switch not pushed
10 kΩ or higher
Lock switch pushed
Below 1 Ω
n1-1 (TRG-) - n1-3 (TRG+)
Lock switch not pushed
10 kΩ or higher
Lock switch pushed
Below 1 Ω

| OK | |
|
| 4. CHECK AND REPLACE ELECTRICAL KEY OSCILLATOR |
Replace the electrical key oscillator.
Check that the entry LOCK / UNLOCK function operates normally.
- OK:
- Entry LOCK / UNLOCK function operates normally.
