Always inspect the harness connectorsthat are involved in the circuit.
Poor 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 a
connection is found, correct the problem and verify that this diagnostic
code is active before performing this procedure.
Perform open or short circuit test ateach harness connection to identify
correct harness to replace.
Perform this test only if condition is active.
Test Step 1. Test 5-Volt Supply Cir-
cuit.
1. Connect MSD (WP 0006). Select
Trans/Chassis 120M ECM and
verify 0262-04 is active.
2. Turn ignition switch and battery

position (TM 5-3805-293-10).
3. Disconnect accumulator harness
connector FG-C2 (WP 0009, Fig-
ure 137) from accumulator pres-
sure sensor (WP 0009, Figure
138) (WP 0233).
4. Using MSD (WP 0006), select
