Operation CHARM: Car repair manuals for everyone.
Manuals through 2025 now available!

Our trusted friends have launched a new website named LEMON, which has newer manuals. It also contains all the CHARM manuals.

LEMON is the spiritual successor to CHARM, I recommend you try it!

Non-Trouble Code Procedures

INPUT SPEED SENSOR CHECK
1. Disconnect the input speed sensor connector.





2. Measure the resistance between the input speed sensor side connector terminals 1 and 2.
Standard value: 0.3 - 1.2 Ohms
3. If the resistance is outside the standard value, replace the input speed sensor.

OUTPUT SPEED SENSOR CHECK
1. Disconnect the output speed sensor connector.





2. Measure the resistance between the input speed sensor side connector terminals 1 and 2.
Standard value: 0.3 - 1.2 Ohms
3. If the resistance is outside the standard value, replace the output speed sensor.

EATX RELAY CHECK
1. Remove the EATX relay.





2. Check the continuity between the EATX relay terminals 4 and 6.





3. Use jumper leads to connect EATX relay terminal 4 to the battery (+) terminal and terminal 6 to the battery terminal.
4. Check the continuity between EATX relay terminals 2 and 8 while connecting and disconnecting the jumper lead at the battery (-) terminal.





5. If there is a defect, replace the EATX relay.

LR SOLENOID CHECK
1. Disconnect the solenoid & pressure switch assembly connector.





2. Measure the resistance between the solenoid & pressure switch assembly side connector terminals 4 and 6.
Standard value: Approximately 1 Ohms [at 20°C (68°F)]
3. If the resistance is outside the standard value, replace the solenoid & pressure switch assembly.

2/4 SOLENOID CHECK
1. Disconnect the solenoid & pressure switch assembly connector.





2. Measure the resistance between the solenoid & pressure switch assembly side connector terminals 3 and 6.
Standard value: Approximately 1 Ohms [at 20°C (68°F)]
3. If the resistance is outside the standard value, replace the solenoid & pressure switch assembly.

OD SOLENOID CHECK
1. Disconnect the solenoid & pressure switch assembly connector.





2. Measure the resistance between the solenoid & pressure switch assembly side connector terminals 6 and 8.
Standard value: Approximately 1 Ohm [at 20°C (68°F)]
3. If the resistance is outside the standard value, replace the solenoid & pressure switch assembly.

UD SOLENOID CHECK
1. Disconnect the solenoid & pressure switch assembly connector.





2. Measure the resistance between the solenoid & pressure switch assembly side connector terminals 6 and 7.
Standard value: Approximately 1 Ohm [at 20°C (68°F)]
3. If the resistance is outside the standard value, replace the solenoid & pressure switch assembly.
