Diagnostic Codes or Event Codes
2. If no active codes are present, the
problem does NOT exist at this
time. Resume normal operation.
2. Remove rear floor plate (WP
0231).
3. Disconnect platform harness left
brake solenoid connector MA-C12
(WP 0018, Figure 67) from left
brake solenoid (WP 0018,
Figure 68).
4. Install a jumper wire between pins
1 and 2 on platform harness left
brake solenoid connector MA-C12
(WP 0018, Figure 67).
5. Check for Diagnostic Codes or

Replace left brake solenoid (WP
0147). Ensure all harness connec-
tors are reconnected. Verify cor-
