Always inspect harness connectors that are involved in the circuit. Poor
Current Above Normal
connections can often be the cause of a problem in an electrical circuit.
Verify that all connections in the circuit are clean and secure and that all
connections are in good condition. If a problem with the connection is
found, correct the problem and verify that this malfunction or diagnostic
code is active before performing this procedure.
Perform open or short-circuit test at each harness connection to identify
the correct harness to replace.
Tag all wiring harnesses to aid in installation.
Perform this test only if condition is active.
DIAGNOSTIC CODE SET CONDITION
Transmission/Chassis ECM Detects Above Normal Current on Upshift Solenoid
Circuit 703.
POSSIBLE CAUSE
Upshift Solenoid.
Transmission Wiring Harness Shorted.
Chassis Wiring Harness Shorted.
Main Cab Wiring Harness Shorted.
Transmission/Chassis ECM.
Test Step 1. Test for Shorted Upshift
Solenoid.
1. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-296-10).
2. Disconnect connector A-C7
(WP 0012, Figure 114) from
upshift solenoid connector
(WP 0012, Figure 113).
3. Turn battery disconnect switch and
ignition switch to ON position
(TM 5-3805-296-10).
4. At MSD, check for active
