KEYLESS UNIT INSPECTION

1. Measure the voltage at the keyless unit terminals (other than terminal L) as indicated below.

3. Disconnect the keyless unit connector (L.H.D.) /short cord connector (R.H.D.) and inspect for continuity between terminal L and the bracket.

5. If the parts and wiring harnesses are okay but the system still does not work properly, perform the troubleshooting.
