59. INTERMEDIATE SPEED WILL NOT ENGAGE.

NOTE

Vehicle MASTER disconnect switch must be ON, ignition switch set to ON, and

clutch pedal fully depressed. Failure to do so will cause erroneous results.

Refer to wiring diagram for all wiring repair steps.

Step 1. Disconnect connector C (1) and check for +24 VDC between wire 23A (2)

and ground.

If +24 VDC is not present, repair wiring 23A between

connector C and connector J.

If +24 VDC is present, reconnect connector C and go to step 2.

Step 2. Check for +24 VDC between wire 23A (2) and ground at air shift solenoid

valve (3).

If +24 VDC is not present, repair wiring 23A between

connector C and air shift solenoid valve.

If +24 VDC is present, notify direct support maintenance.
