Transmitter ID code cannot be reprogrammed
DESCRIPTION
•  Malfunction in transmitter battery, transmitter, PJB circuit, or keyless control module circuit.
POSSIBLE CAUSE
•  Malfunction in transmitter battery, transmitter, PJB, or keyless control module.

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 (normal type), CR1620 (retractable type)
Yes
Go to the next step.
No
Properly install the battery or replace the battery with the specified battery (CR2025 (normal type), CR1620 (retractable type)), and 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 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.
5
INSPECT IF MALFUNCTION IS IN TRANSMITTER OR PJB
•  Reprogram the transmitter 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.
6
INSPECT POWER SUPPLY FUSE
•  Is the keyless control module power supply fuse normal?
Yes
Go to the next step.
No
Install an appropriate amperage fuse, then go to Step 11.
7
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 control module terminal:
―  Power supply signal (terminal A)
•  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.
8
INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN KEYLESS CONTROL MODULE AND GROUND) OR ELSEWHERE
•  Is there continuity between keyless control module terminal E 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.
9
INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN KEYLESS CONTROL MODULE AND PJB) OR ELSEWHERE
•  Disconnect the keyless control module connector and PJB connector.
•  Is there continuity between the following terminals?
―  J-04-F (PJB connector)—C (keyless control module connector)
Yes
Go to the next step.
No
Repair the wiring harness between the keyless control module and PJB, then go to Step 11.
10
INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN KEYLESS CONTROL MODULE AND PJB) OR PJB
•  Measure the voltage at PJB terminal C.
―  When transmitter operated:
•  Any transmitter button is operated without key in steering lock (key reminder switch off): 5 V
•  Key is in steering lock (key reminder switch on): Below 0.5 V
•  Is the voltage normal?
Yes
Replace the PJB, then go to the next step.
No
Replace the keyless control module, then go to the next step.
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.
