From VIN # 350001

Component Description
IGNITION COIL & POWER TRANSISTOR



The power transistor switches on and off the ignition coil primary circuit according to the ECM signal. As the primary circuit is turned on and off, the proper high voltage is induced in the secondary circuit. The distributor is not repairable except for the distributor cap and rotor head.

NOTE: The rotor screw which secures the distributor rotor head to the distributor shaft must be torqued properly.

Torque : 3.6 ± 0.3 N.m (37 ± 3 kg-cm, 32 ± 3 in-lb)

Terminal No. 1 - 2:

ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and 32 (ECM ground).


DTC Confirmation Procedure

On Board Diagnosis Logic:

NOTE:
- If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.
- If DTC P1320 (0201) is displayed with P0340 (0101), perform trouble diagnosis for DTC P0340 first.

With CONSULT
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT.




3. Start engine. (If engine does not run, turn ignition switch to "START" for at least 5 seconds.)
4. If 1st trip DTC is detected, go to "Diagnostic Procedure".

With GST
1. Start engine. (If engine does not run, turn ignition switch to "START" for at least 5 seconds.)
2. Select MODE 7 with GST.
3. If 1st trip DTC is detected, go to "Diagnostic Procedure".

No Tools
1. Start engine. (If engine does not run, turn ignition switch to "START" for at least 5 seconds.)
2. Turn ignition switch "OFF" and wait at least 5 seconds, then turn "ON".
3. Perform "Diagnostic Test Mode II" (Self-diagnostic results) with ECM.
4. If 1st trip DTC is detected, go to "Diagnostic Procedure".

Component Inspection

IGNITION COIL
1. Disconnect ignition coil harness connector.










2. Check resistance as shown in the figure.
For checking secondary coil, remove distributor cap and measure resistance between coil tower metal tip 9 and terminal 7. If NG, replace distributor assembly as a unit.

POWER TRANSISTOR
1. Disconnect camshaft position sensor & power transistor harness connector and ignition coil harness connector.







2. Check power transistor resistance between terminals 2 and 8.
If NG, replace distributor assembly.

RESISTOR
1. Disconnect resistor harness connector.




2. Check resistance between terminals 1 and 2.

Resistance: Approximately 2.2 kohms [at 25°C (77°F)]
If NG, replace resistor.
