Diagnostic procedure

STEP

INSPECTION

ACTION
1
INSPECT TRANSMITTER BATTERY INSTALLATION AND TYPE
•  Visually inspect the transmitter battery.
•  Are the below items correct?
―  Transmitter battery installation (correct polarity)
―  Battery type (CR2025)
Yes
Go to the next step.
No
Install the transmitter battery properly or replace with the specified transmitter battery (CR2025), then go to Step 11.
2
INSPECT TRANSMITTER BATTERY TERMINALS FOR RUST AND POOR CONNECTION
•  Visually inspect the transmitter.
―  Is there rust on the transmitter battery terminals (positive or negative)?
―  Is there poor connection between the terminals and battery?
Yes
Replace the transmitter battery or repair the transmitter battery terminal, then go to Step 11.
No
Go to the next step.
3
INSPECT TRANSMITTER BATTERY
•  Inspect the transmitter battery.
•  Is the battery voltage normal?
Yes
Go to the next step.
No
Replace the transmitter battery, then go to Step 11.
4
INSPECT KEYLESS RECEIVE BRACKET INSTALLATION
•  Is the keyless control module bracket installed securely?
Yes
Go to the next step.
No
Install bracket securely, then go back to Step 6 of KEYLESS ENTRY SYSTEM PRELIMINARY inspection.
5
INSPECT GROUND SCREW INSTALLATION BETWEEN KEYLESS RECEIVE AND KEYLESS RECEIVE BRACKET
•  Are the keyless receive and keyless receive bracket connected securely to the ground screw?
Yes
Go to the next step.
No
Install the screw securely, then go back to Step 6 of KEYLESS ENTRY SYSTEM PRELIMINARY inspection.
6
INSPECT IF MALFUNCTION IS IN TRANSMITTER BATTERY OR ELSEWHERE
•  Replace with a transmitter battery known to be good.
•  Does the keyless entry system operate properly?
Yes
Replace the transmitter battery, then go to Step 11.
No
Go to the next step.
7
INSPECT IF MALFUNCTION IS IN TRANSMITTER OR KEYLESS CONTROL MODULE
•  Reprogram the keyless control module ID code using another known good transmitter.
•  Does the keyless entry system operate properly?
Yes
Replace the transmitter and reprogram the transmitter ID code, then go to Step 11.
No
Go to the next step.
8
INSPECT POWER SUPPLY FUSE
•  Is the keyless receiver power supply fuse normal?
Yes
Go to the next step.
No
Inspect for a short to ground in circuit of blown fuse. Repair or replace if necessary.
Install an appropriate amperage fuse, then go to Step 11.
9
INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN FUSE BLOCK AND KEYLESS CONTROL MODULE) OR ELSEWHERE
•  Measure the voltage at the following keyless receiver terminal:
―  Power supply signal (terminal 1A)
•  Is the voltage B+?
Yes
Go to the next step.
No
Repair the wiring harness between the fuse block and keyless control module, then go to Step 11.
10
INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN KEYLESS CONTROL MODULE AND GROUND) OR ELSEWHERE
•  Is there continuity between keyless control module connector terminal 1E and ground?
Yes
Go to the next step.
No
Repair the wiring harness between the keyless control module and ground, then go to Step 11.
11
REINSPECT MALFUNCTION SYMPTOM AFTER REPAIR
•  Does the keyless entry system operate properly?
Yes
Troubleshooting completed.
Explain repairs to the customer.
No
Reinspect the malfunction symptoms, then repeat from Step 1 if the malfunction recurs.
