tion.
4. Using digital multimeter, measure
Voltage OK (7.2 - 8.8 Volts) - 8 Volt
voltage between P-C48 (WP

Step 3.
5. Using digital multimeter, measure
Voltage OK (7.2 - 8.8 Volts) - Sensor
voltage between P-C48 terminal 1
signal circuit, transmission and imple-
(WP 0009, Figure 116) and termi-

between 7.2 and 8.8 volts.
Proceed to step 6.
Voltage Not OK - Sensor signal cir-
cuit shorted or transmission or imple-
ment ECM bad, proceed to Test Step
5.
6. Using the MSD (WP 0006), select
1473-02 Code Active - Repeat trou-
Trans/chassis 120M and verify
bleshooting code from the beginning.
1473-02 is not active.
1473-02 Code Not Active - Trouble-
shooting complete.
Test Step 3. Test for Open Rear

Power Supply.
1. Turn ignition switch and battery
disconnect switch to the OFF
position.
2. Disconnect the cab lower wiring
harness connector P-C51 (WP
0009, Figure 118) from LH joy-
stick connector J-1 (WP 0009,
Figure 117) (WP 0282).
3. Connect jumper wire between P-
C48 terminal 2 (WP 0009, Figure
116) and P-C51 terminal 3 (WP
0009, Figure 118).
