October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Electronic DISTRIBUTORLESS Ignition System (EDIS) Module
- Remove EDIS module connector. Measure resistance between module terminal No. 4 (IGND) and No. 9 (GND). See EDIS MODULE PIN IDENTIFICATION
. If resistance is less than 5 ohms go to Step 2. If resistance is more than 5 ohms, replace EDIS module and check for fault codes. See TESTS W/CODES
article.
- With key off, check resistance between EDIS module harness connector terminal No. 4 and ECA connector pin No. 16 (IGN GND) of the ECA connector. See Figure
. If resistance is less than 5 ohms, replace EDIS module and rerun test. If reading is more than 5 ohms, service open circuit, reconnect ECA and check for fault codes. See TESTS W/CODES
article.
