Code 0201

Ignition coil & power transistor
The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit.







DIAGNOSTIC CHART




DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

NOTE:
- If both DTC 0201 (P1320) and DTC 0101 (P0340), 0407 (P1335), 0802 (P0335) or 0905 (P1336) are displayed, perform TROUBLE DIAGNOSIS FOR DTC 0101, 0407, 0802 or 0905 first.

CONSULT
1) Turn ignition switch "ON".
2) Select "DATA MONITOR" mode with CONSULT.
3) Start engine. (It engine does not run, turn ignition switch to "START"for at least 5 seconds.)

OR

GST
1) Turn ignition switch "ON".
2) Start engine. (If engine does not run, turn ignition switch to "START"for at least 5 seconds.)
3) Select MODE 3 with GST.

OR

NO TOOLS
1) Turn ignition switch "ON".
2) Start engine. (If engine does not run, turn ignition switch to "START" for at least 5 seconds.)
3) Turn ignition switch "OFF", wait for at least 5 seconds and then turn "ON".
4) Perform diagnostic test mode II (Self-diagnostic results) with ECM.

COMPONENT TEST







Ignition coil with power transistor
1. Disconnect ignition coil with power transistor harness connector.
2. Check ignition coil with power transistor for resistance between terminals (1) and (2).




Condenser
1. Disconnect condenser harness connector.
2. Check condenser continuity between terminals (1) and (2).

Resistance: Above 1 M Ohms at 25°C (77°F)
