Ignition Coil Relay Circuit Troubleshooting
Ignition Coil Relay Circuit Troubleshooting
1. Check the No. 2 (15 A) fuse in the driver's under-dash fuse/relay box.
Is the fuse OK?
YES - Go to step 2.
NO- Replace the fuse.
2. Remove the ignition coil relay from the driver's under-dash fuse/relay box, and test it.
Is the relay OK?
YES - Go to step 3.
NO- Replace the ignition coil relay.
3. Measure the voltage between ignition coil relay 4P socket terminal No. 1 and body ground, then terminal No. 4 and body ground.
Is there battery voltage?
YES - Go to step 4.
NO- Replace the driver's under-dash fuse/relay box.
4. Check for continuity between ignition coil relay 4P socket terminal No. 2 and the No. 1 ignition coil 3P connector terminal No. 3.
Is there continuity?
YES - Go to step 5.
NO- Repair an open in the wire between ignition coil relay 4P socket terminal No. 2 and No. 1 ignition coil 3P connector terminal No. 3.
5. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC). Turn the ignition switch ON (II), and jump the SCS line with the
HDS, then turn the ignition switch OFF.
NOTE: This step must be done to protect the powertrain control module (PCM) from damage.
