Power Supply Circuit
- Measure voltage between fuse box connector (B158) terminal No. 8 and chassis ground. See Fig 1
. If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair wiring harness between fuse box and battery.
- Disconnect connector from keyless entry control module. Measure voltage between connector terminal No. 3 and chassis ground. See Figure
. If voltage is greater than 10 volts, check ground circuit. See GROUND CIRCUIT
. If voltage is less than 10 volts, repair wiring harness between keyless entry control module and fuse box.
