The module is mounted in the distributor housing next to the coil. To access it, remove the distributor cap, rotor and dust cover (on car parts).
Examination
Before removing, mark all wires on the module.
CR-V Models
1. Remove the distributor cap and rotor, mark and disconnect the wires from the module.
2. Turn on the ignition and check for battery voltage between ground and the black/yellow wire. If there is no voltage, check the circuit between the ignition switch and the black/yellow wire of the module.
3. With the ignition on, check for battery voltage between ground and the white/blue wire. If there is no voltage, check the ignition coil and the presence of a break in this wire.
4. Disconnect the connector on the engine processor unit and check the continuity between the yellow/green wire terminals on the processor unit and on the module. If there is no circuit, check for a break in this wire, check the circuit between the yellow/green wire and ground (there shouldn't be a chain).
5. On 1997-98 models, check for continuity between the blue wire on the ignition module and the tachometer connector (mounted on the wall of the engine compartment). Make sure there is no short to ground on this wire.
6. The module is considered faulty if, after troubleshooting the wires, (breaks or short circuits) the results of all tests are negative.
4-cylinder Odyssey
On 1995 models, disconnect the black/yellow (1) and blue (2) wires from the module.
On 1996-97 models, disconnect the yellow/green, black/yellow, and blue wires from the module.
On 1998 models, disconnect the yellow/green and black/white wires from the module.
1. With the ignition on, check for battery voltage between the black/yellow wire and ground. If there is no voltage, check the circuit between the ignition switch and the black/yellow wire terminal.
2. With the ignition on, check for battery voltage between the white/black wire (1996-97), or blue wire (2) wire (1995), and ground. If there is no voltage, check the ignition coil and check for an open in these wires between the coil and the module.
3. Disconnect the connector on the engine processor unit and check the continuity between the yellow/green wire terminals on the processor unit and on the module. If there is no circuit, check for a break in this wire, check the circuit between the yellow/green wire and ground (there shouldn't be a chain).
5. On 1995 models, check for continuity between the blue wire (1) on the ignition module and the corresponding terminal on the transmission control module connector (TSM - module). Make sure there is no short to ground on this wire.
6. On 1996-97 models, check the continuity between the blue wire terminal and the tachometer connector (mounted on the wall of the engine compartment on the right side). Make sure there is no short to ground on this wire.
7. The module is considered faulty if, after troubleshooting the wires, (breaks or short circuits) the results of all tests are negative.
Removal and installation
1. Remove the distributor cap and rotor, mark and disconnect the wires from the module.
2. Disconnect the wires from the module.
On CR-V models, disconnect the yellow/green, black/yellow, and white/blue wires from the module.
On 4-cylinder Odysseys:
- on the 3-pin connector, disconnect the yellow/green, black/yellow and white/black wires from the module.
- on the 4-pin connector, disconnect the harness with black/yellow, blue and yellow/green wires, disconnect the black/white or blue (1) wire and the separate blue (2) wire from the module.
3. Loosen the mounting screws and remove the module.
4. Assembly is carried out in reverse order.
