DIAGNOSTIC CODE 3-5 (ELECTRICAL)

Test 1

Checking for an open or short in the solenoid

Test 2

Checking for a short to ground in the solenoid

1.Turn the ignition key to the OFF position.

2.Disconnect the timing solenoid from the harness.

3.Measure the resistance across the leads of the solenoid.

If the resistance is between 1 and 3 ohms, proceed to Test 2.

If the resistance is not between 1 and 3 ohms, repair the connector or replace the solenoid. Retest to be sure the problem has been corrected.

1.Check for continuity from either solenoid lead (pin A or B) to a good ground.

If there is continuity, replace the solenoid. Retest to be sure the problem has been corrected.

If there is no continuity, proceed to Test 4.

DIAGNOSTIC CODE 3-5 (ELECTRICAL) Test 4

Checking for a short to voltage in the harness

1.Disconnect the J1A and J1B connectors from the V-MAC II module.

2.Connect the serial link jumper into the serial communication port.

3.Measure the voltage from J1A connector pin A1 (the timing solenoid PLUS [+] line) to a good ground.

4.Measure the voltage from J1A connector pin A3 (the solenoid MINUS [ ] line) to a good ground.

If the voltage on either line is greater than 0.5 volts, that line is shorted to another line in the harness. Locate and repair the short. Retest to be sure the problem has been corrected.

If the voltage on both lines is less than 0.5 volts, proceed to Test 8.
