BHE090369000W06

3 | Transmitter ID code cannot be reprogrammed
DESCRIPTION | • Malfunction in transmitter battery, transmitter, keyless receive bracket, keyless receive bracket ground screw, or keyless unit circuit. keyless receive circuit.
POSSIBLE CAUSE | • Malfunction in transmitter battery, transmitter, keyless receive bracket, keyless receive bracket ground screw, or keyless unit, or keyless receive.

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 13.
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 13.
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 13.
4 | INSPECT KEYLESS RECEIVE BRACKET INSTALLATION • Is the keyless receive 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 13.
No | Go to the next step.
7 | INSPECT IF MALFUNCTION IS IN TRANSMITTER OR KEYLESS UNIT • Reprogram the keyless unit 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 13.
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 13.
9 | INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN FUSE BLOCK AND KEYLESS RECEIVER) 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 receiver, then go to Step 13.
10 | INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN KEYLESS RECEIVER AND GROUND) OR ELSEWHERE • Is there continuity between keyless receiver connector terminal 1E and ground? | Yes | Go to the next step.
No | Repair the wiring harness between the keyless receiver and ground, then go to Step 13.
11 | INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN KEYLESS RECEIVER AND KEYLESS UNIT) OR ELSEWHERE • Disconnect the keyless receiver connector and keyless unit. • Is there continuity between the following terminals? – Terminal 1B-terminal 2N – Terminal 1C-terminal 2P | Yes | Go to the next step.
No | Repair the wiring harness between the keyless receiver and keyless unit, then go to Step 13.
12 | INSPECT IF MALFUNCTION IS IN WIRING HARNESS (NO CONTINUITY BETWEEN KEYLESS RECEIVER AND KEYLESS UNIT) OR KEYLESS UNIT • Measure the voltage at keyless unit terminal 2N. – When transmitter operated: • Any transmitter button is operated without key in steering lock (key reminder switch off): 5 V→1.0 V or less • Key is in steering lock (key reminder switch on): 5 V • Is the voltage normal? | Yes | Replace the keyless unit, then go to the next step.
No | Replace the keyless receiver, then go to the next step.
13 | 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.
