DTC B1036: IG1 Power Supply Circuit Malfunction

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).

Clear the DTCs with the HDS.
Turn the ignition switch to LOCK (0) and then back to ON (II).
Wait for at least 6 seconds.
Check for DTCs with the HDS.
Is DTC B1036 indicated?

YES -Go to step 5.

NO -Intermittent failure, the system is OK at this time. Check for loose or poor connections at the gauge control module 32P connector and at under-dash fuse/relay box connector Q (16P). If the connections are good, check the 12 volt battery condition (see 12 VOLT BATTERY TEST ) and the charging system.
Measure the voltage between gauge control module 32P connector terminal No. 15 and body ground.

Is there battery voltage?

YES -Faulty MICU or an open in the under-dash fuse/relay box internal circuit. Substitute a known-good under-dash fuse/relay box, and recheck.

NO -Check the No. 22 (7.5 A) fuse in the under-dash fuse/relay box. If the fuse is OK, check for an open in the wire between the under-dash fuse/relay box and the gauge control module, or repair a short in the wire between the under-dash fuse/relay box and the gauge control module.
