Ignition Control Module: Testing and Inspection
1993 Honda Accord L4-2156cc 2.2L SOHCSECTION Testing and Inspection
NOTE:
- See Computers and Control Systems" when MIL blinks.
- Perform an input test for the igniter unit after finishing the fundamental tests for the ignition system and emission system.
- The tachometer should operate normally if the igntion control module (Igniter) is ok.
1. Remove the distributor cap, the rotor and the inner cover.
2. Disconnect the BLK/YEL, LT GRN, YEL/GRN and BLU wires from the igniter unit.
3. Turn the ignition switch ON and check for battery voltage between the BLK/YEL wire and body ground. If there is no battery voltage, check the BLK/YEL (YEL) wire between the ignition switch and the igniter unit. If there is battery voltage proceed to step 4.
4. Turn the ignition switch ON and check for battery voltage between the LT GRN wire and body ground. If there is no battery voltage check the ignition coil for proper operation or for an open circuit on the LT GRN (BLK/WHT) wire between the ignition coil and the igniter unit. If there is battery voltage proceed to step 5.
5. Check the YEL/GRN wire between the PGM-FI ECU and the igniter unit.
6. Check the BLU wire between the tachometer and the igniter unit.
7. Using an ohmmeter, measure the resistance between the terminals which connect to the BLU and LT GRN wires.
Resistance: 1.1 - 3.3 kohms
8. If all tests are normal, replace the igniter unit.
RENDER: 1.0x

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
