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 ).
Scheme 14
- 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 36P connector and under-dash fuse/relay box connector Q (16P). If the connections are good, check the battery condition (see «BATTERY TEST»(ref-371357-S38076907072010091000000) ) and the charging system.
- Check for DTCs with the HDS. Is DTC B1008 indicated with DTC B1036? YES -Go to «DTC B1008 TROUBLESHOOTING»(ref-371394-S22795464472010091000000) . NO -Go to step 6.
- Turn the ignition switch to LOCK (0).
- Turn the ignition switch to ON (II).
- Measure voltage between the gauge control module 36P connector terminal No. 36 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 (see «REMOVAL AND INSTALLATION»(ref-371395-S18403628942010091000000) ) and recheck. NO -Check the No. 10 (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.
