Circuit/System Testing

1. Ignition OFF, disconnect the KR27 starter relay.

2. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 10 Ohms between the relay

ground circuit terminal 85 and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify a test lamp illuminates between the B+ circuit terminal 30 and ground.

瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

瀚慖f the circuit tests normal and the B+ circuit fuse is open, test the control circuit terminal 87 for a short to ground.

4. Ignition ON, verify that a test lamp does not illuminate between the control circuit terminal 87 and ground.

瀚慖f the test lamp illuminates, test the control circuit for a short to voltage.

5. Parking brake applied and the transmission is in NEUTRAL or PARK. Momentarily install a 30 A fused jumper wire between the B+ circuit

terminal 30 and the control circuit terminal 87. Verify the starter is activated.

瀚慖f the starter does not activate, test the control circuit for an open/high resistance. If the circuit tests normal, test or replace the starter.

6. Ignition OFF, connect a test lamp between the control circuit terminal 86 and the ground circuit terminal 85.
