Test 38, Check Base Timing

Turn key off. Connect EDIS Diagnostic Cable (007-00059) to breakout box (T83L-50-EEC-IV), EDIS module and coil pack. DO NOT connect VR sensor tee. See Figure. Use EDIS No. 6 overlay. Connect EDIS diagnostic cable negative and positive leads to battery. Set EDIS diagnostic cable box switch to 4/6 CYLINDER position. Connect timing light (must be DIS/EDIS compatible).

Start engine, and bring to normal operating temperature. Check timing. If timing is 10+/-2 degrees BTDC when EDIS diagnostic cable SAW DETECTOR button is pushed, go to next test. If timing is not 10+/-2 degrees BTDC when EDIS diagnostic cable SAW DETECTOR button is pushed, go to TEST 45.
